Opus vs aac reddit. But after that it really isn't better.
Opus vs aac reddit AAC can offer great quality at low bitrates thanks to the fact that it is perceptually coded, but Android phones tend to have mediocre implementations. Or follow the rule that codecs are better than the generation before, 320kbps mp3 = 256kbps AAC = 192kbps Since yesterday I've been doing heavy ABX tests on 128kbps Opus vs others at 96 to 256k, It's pretty much the quality of 192 to 320kbps AAC/Vorbis/MP3. m4a, . As an audiophile and a hobbyist mixing/mastering engineer, I'm familiar with mp3 and AAC files and their differences from lossless, but not Ogg. For most use cases, yes. 1 lossy. opus is newer and supposed to be superior to mp3 and aac, transparent at lower bitrates. Get the Reddit app Scan this QR code to download the app now. You may be better going with AAC as it is more commonly accepted by most programs (if you're doing any editing for example) compared to Vorbis. Ffmpeg has a good implementation and opus works for a lot of use cases where you would otherwise use aac. MP3 was created in the mid 1990s and Opus was created in the early 2010s, so Opus is definitely more efficient and can do what you want. I only went with AAC, Google search for aac conversion shows this result. This is perplexing because YouTube Music uses 256 KBPs AAC, so there doesn't seem to be a need for transcoding if my headphones are set to use AAC. This thread was a great. Personally, the heuristics I use are based on generation loss, height channel retention, and the fact that Apple devices only support MP4 containers with up to stereo Opus, surround sound AAC or AC3, and studio-encoded AC3 Dolby Atmos: Just to add - AAC is able to achieve higher perceived quality because the algorithm allows for sections to be above 320kbps, and limits sections which do not need to be. There is only a very small difference to aac 256. exe before encoding) Now why should you still keep Loseless Music One is Opus and the other is the DTS track that's copied over for theatre use. I use both and am happy with both. We know Signal was using Opus for live calls as of 2017 so it’s surprising they’d use AAC for voice messages. What I'm not understanding is that, anecdotally speaking, music has better instrument separation and soundstage using SBC, no matter if the source material is AAC, FLAC, or MQA. bitrate, but the encoders can be relatively CPU heavy, and the minimum latency is also high, like MP3. ogg vorbis may be worse than aac. I did some codec testing with my dt770 pros. Or check it out in the app stores AAC to Opus: how to keep stereo (und): Audio: opus (libopus), 48000 Hz, stereo, flt, 96 kb/s (default) So yeah I have no idea why you got mono in the first place. I do understand without professional/paid Dolby Encoder software on a MAC, FFMPEG is limited to 5. Expand user menu Open settings menu. If your playback devices support it, you could absolutely use it. In the past I had encoded to AAC and then eventually switched to Opus for my media library because of the great space efficiency and support for up to 7. If you're starting out with a lossy track (DTS, AC3, AAC, MP3, M4A etc), don't touch it. People are more used to mp3 and aac What's happening behind the scenes at YouTube is that however people submit the audio files, YouTube first converts the original audio to the audio-only . Opus is the best lossy audio codec at the moment, and delivers significant bitrate savings over AAC and AC3, with 256kbps Opus When using ytdlp -F, you will see that YouTube presents Opus and M4A audio-only formats. Open menu Open navigation Go to Reddit Home. Most home cinema equipment will run AC3, most computer and mobile devices will run AAC. 251 opus ~128kbps 48kHz 250 opus ~64kbps 48kHz 249 opus ~48kbps 48kHz 600 opus ~32kbps 48kHz 140 aac ~128kbps 44kHz 139 aac ~48kbps 22kHz 599 aac ~32kbps 22kHz Sources: - I usually prefer 251 when downloading music and videos and 249 for audiobooks. 1ch E-AC-3 audio @ 640 kb/s Is it possible to compress in OPUS codec and gain space? if I convert to Opus, r/AppleMusic is the place to discuss Apple Music on Reddit! Members Online. You're right AAC is better. Best Efficiency. It does bother me that Opus doesn't do any sample rates other than 48. 15 years ago I made a huge listening test at ∼130 kbps: that guided me to Apple’s AAC for my portable usage. However, I recently switched to E-AC3 because it sounded better when I bitstreamed it to my receivers to decode as opposed to having the Opus tracks decoded in software on the streaming device. Opus is the best audio codec included in ffmpeg. Perhaps it could give us better internet radio in the future. That's just release date. Now I only can see HD Audio On/Off without codec name (was before AAC) - maybe bug in my language. AAC is really only good for mobile devices because home theater equipment doesn't really support it (gear has to decode it at the source into PCM) and I don't know anything that supports it in more than 2 channels. • audio·phile: a person with love for, affinity towards or obsession with high-quality playback of sound Just got the update. However, for lower bitrate while still being 99% transparent to lossless, something like opus 128kbps or Apple AAC 150 kbps VBR will meet your needs nicely. not clustering by rater). Is OPUS a better one to use than e-AC3? I see stuff converted to random things like MP3, OPUS, and AAC. And of They have none of the master files for the older stuff. so AAC shouldnt transcode, but FLAC should. it uses more of the bitrate in places where it need it. If they came from a different master, then the better-mastered copy will sound better. Spotify web actually uses AAC at the same bit rate, so that at least should be the same. Archived post. On one hand I could see Plex trying to dodge legalities, because it is Dolby's IP. No settings changed made by me. Hello Guys This is my first post here Iwonder how good EAC3 compared to AAC and opus in the same bitrate for stereo mix ?

It may still be a good choice on Android though, because of the issues with the other Which is great for a lot of services that really need that. That is transparent also. Opus is arguably superior than HE-AAC. However once you compress something you can no longer increase its quality afterwards by converting to something else. The mode I'm working on could, theoretically, allow the OS to skip mixing and encoding, and just send the Opus frames Hours in the day for a freeware project and the limitations of its current platform. m4a(aac) is more widely supported. aac files are usually an MPEG-2 container first used when AAC was released but lacked a dedicated container format. Log In / Sign Up; Opus achieves transparency at 64kbps, vorbis at 96kbps, i havent used ymusic, but if it's offering 320 kbps mp3 it is just converting from something like 160 kbps opus or 128 aac. OPUS and AAC bother are lossy codings. Log In / Sign Up; MP3 vs. Thank you for answering the question, this is great information, particularly about Spek! What I had in mind is something along the lines of taking my 128kbps AAC files and transcoding them to something like an absurd 320kbps Opus like you said, but this gives me a way to know specifically how much fidelity is lost! I made a little experimenting with the same audio file, that consisted of a song. quality can only get worse from that conversion, although the difference is potentially unnoticeable. Encoding stereo or surround FLAC to a lossy format like opus is a fairly simple process that can be done in seconds and will not lead to any desyncs. You may want to consider going straight to lossless PCM audio if you are recording. You can do it pretty quickly and easily just using ffmpeg. ) and worst of all the metadata of opus files like its tags (which I would have manually added in via MP3tag or some other software) does not show up. That's because Opus has some fancy encoding tricks that let it preserve more of the little details, especially in complex tunes. ogg supports either vorbis or flac. The main reason is that MP3 requires a license to use while Opus is free. Honestly though, for archiving purposes since you're ripping CDs I'd just rip them in a lossless format like TAK (slightly faster and better compression than FLAC), FLAC, monkey's audio etc. Though AAC is a much newer and more efficient codec compared to AC3, I think you'd struggle to hear much difference at 640kbps. m4a file an ID number of 140. It's what format is compatible with all the OPUS excels in preserving the clarity and detail of audio, making it suitable for real-time communication applications. The main issue with ffmpeg's AC3 and EAC3 encoding is that it's not official Right Click > Convert > Quickconvert > Opus > Choose Bitrate > Choose Export Directory > Done : ) PS: I will rather do 256kbps CBR AAC using iTunes Encoder (Best lossy format imo) ! (same steps just choose aac (apple) option and you need itunes installed and locate qaac. AAC encoding speed . It's been great. I'm having a hard time finding scientific tests about Apple Music vs Spotify, or AAC vs OGG Vorbis. AAC is not as good as opus, patent encumbered and higher latency lacks a voice mode so is horrible with voice compared to Opus / 32Kbs. I don't know the technical stuffs of a codec but If a file loses it's bit depth. But when I convert 24bit FLAC to AAC(16bit). ; Disadvantages of OPUS. Or Vorbis vs AAC @ 192kbps vbr . But the encoder wasn't tuned for The only thing you lose with AC3 is object-based metadata like you would have in Dolby Atmos or DTS:X tracks. Opus is even better than AAC, but it doesn’t enjoy as much support — notably, Apple’s first-party apps support stereo Opus, but not Opus with more than two channels. I would be more concerned with compatibility. Lots of music vendors offer AAC as a download option, so it's not exclusive to Apple. Don't even bother setting a bitrate, just use qaac -v100 opus 160 should technically be better, but you may not hear the difference, 128 m4a is pretty good. About audio, no doubt opus is best . AAC is a close second, and more compatible at this point. however, if you're transferring the files to a device such as a smart tv, dvd player or perhaps a vintage 2004 creative zen.

As to Eac-3, it does support more channels so you can go 6. Pure-audio opus matroskas should be . I created a script that checked the start_time and used ffmpeg with AAC has good quality vs. In terms of quality I’d go with AAC (on my LG C1 AAC plays fine up to 5. The quallity of opus is amazing and still it uses less bitrate than any other of the So are you asking about Spotify 128 kbps AAC vs. Yes AAC is a much more efficient codec but when it’s not native I think it’s better to leave it as is if you’ve got the storage space. AAC in terms of compression are a wash I'd say. I think if I converting WAV or some other uncompressed audio, I'd go with Opus now. I only have wired headphones and for Bluetooth I don't know if my Honda cars support SBC or AAC. HE-AAC stops working after 96kbit, where you want to use regular AAC instead, but I believe Opus is still competitive (and usually the winner) there. 2M subscribers in the audiophile community. I found a huge difference. 1 audio(258 aac) and ambisonic audio(338 opus) have the sample rate of 48000, including 251(best opus track). Discussion (mp3 (control)) the ogg and We're now read-only indefinitely due to Reddit Incorporated's poor AAC isn't as good as opus, but tends to be more supported. Just curious more than anything, if they've implemented Opus the browser like they have in the applications. Unless you're limited in bandwidth I wouldn't chase a low bar. Although Opus is very good at a variety of audio, it does not necessarily beat all other lossy codecs in every If you're not keeping AC3 for bitstreaming or compatibility purposes, Opus or AAC would sound excellent and save a ton of space. Opus vs HE-AAC 2018-03-29 03:06:40. Yesterday I was trying different compression codecs (MP3, AAC, Opus) against FLAC (Lossless) and while MP3 at 128 kbps and the other codecs at lower bitrates had noticeable compression degradation and artifacts, 128 kbps AAC was almost transparent, even at 96 kbps it And about av2, it is supposed to be more efficient than vvc, but it will still take 4-5 years after release to be mature enough for encodes. Question So i did a blind test One audio track from ytm and one audio track from youtube app. Get app Get the Reddit app Log In Log in to Reddit. But shouldn't the m4a file be smaller in size since it carries less information? Or is the site I'm downloading from misleading me? If anyone can clarify this for me (as well as explain a bit what the difference is between an m4a file and an opus file), it would be most There is lot of sound quality difference between the two. Note that you can put Opus in an Ogg container, though I believe it's usually in a Matroska container. Objective measures of quality can't go up by transcoding from one format to another. First off, we don't know the quality of the source audio that was uploaded to YT. m4a in fact regular aac files have more confusion in itself. OPUS resamples everything to 48kHz and back internally, so that might be a dealbreaker if your original content is at a rate other than 48kHz. The extension of OPUS is . Both 5. It’s transparent at 128kbps stereo, and things Bad software support, really (VLC, Steam, GStreamer, Firefox, Chrome, Chromecast, Android 5+). I have a series with 5. There are some newer flavors of AAC that supposedly are better at low bitrates than OPUS, but those often aren't as widely supported. Assuming your output container is MKV, encode the video on its own (or with a basic AAC encode) then use MKV Merge (part of MKVToolNix) to mux (combine) your newly encoded video track with your original Opus audio track (and any subtitles if required), giving you a new MKV exactly the way you want. It should reduce each PCM file by around 30% without any audio loss. When the opus version is better than the m4a version, even those with really good hearing report that it's only just barely better and is difficult to notice. Spotify has volume normalisation, which could change songs a tiny bit, but basically every provider does that, because old recordings can't really be -40 But when doing your own transcodes, AAC is higher-quality at the same bitrates as AC3 variants (of which EAC3 is one). On the other hand, AAC offers better sound quality compared to older audio codecs like MP3 at the same bitrate. And finally to really screw with your brain good and proper, the MPEG-4 container can contain FLAC encoded streams (or Opus, AAC, heck it can even contain MP3 meaning that the file name extension doesn't tell you what type of HE-AAC is opdimized for lower bitrate encodes. I'm converting from a TrueHD Atmos source to 5. Ogg Vorbis comes close and is widely supported, so it's not a big deal. 1 channels and can't transfer the Since most video software encodes the audio track as AAC, the AAC track Youtube provides is likely an AAC -> AAC transcode, which will be better than an AAC -> Opus transcode. 256kbps is set as the average because the average section in the average song, at the time of the format’s conception, only needed 256kbps to be psychoaustically optimal (at least according to the engineers Well, see above where I question the validity of treating the ratings as independent (i. OPUS 256 compared with AAC 256, both VBR. Give or take. The only negative with Opus right now is lack of proper ReplayGain support. I suspect quality is the least important discriminator between the two. m4a files are an MPEG-4 Part 14 container. I converted my library from FLAC to 256K AAC (m4a). The Opus codec is license-free, so can handbrake convert with the same quality compared to other programs? This gets the highest quality "Opus" and converts it to Apple ALAC, if you just want the Opus then ignore the part after &&. Both Ogg and m4a are just containers, but the formats they usually encode (either Vorbis or Opus, in ogg, or one of the AAC profile or occasionally ALAC in m4a) are all newer, more efficient and better sounding than mp3, and with fewer artifacts and killer samples. 1 is just a wide stereo. aac since they are interchangeable to some degree by the standards. ogg are usually ogg/vorbis (but can be ogg/opus, . If you're starting with a lossless source, such as DTS-HD MA, Dolby TrueHD, FLAC, or PCM, the best format to use, in terms of quality to space ratio, is Opus. I use opus in my mp4 videos that I ultimately watch in web browsers without any issues. I ran a test of converting a song to 128 kbps Opus (from a lossless source) and it sounded quite good. Regardless, HE-AAC v1 does not utilize PS and begs the question why mp3 is still in use even though HE-AAC v1, or AAC for that matter, is compatible with so many operating systems and software. TLDR the conclusion here is that the best sounding aac encoder varies slightly based on what bitrate you are planning to run with. aac. For that matter, even if you were comparing 192kbps mp3 to uncompressed, if the masterings are different, the better-sounding one will be the one that came from the better On windows opus files take forever to load (not a second or two but many seconds, if a file contains like a hundred opus files even just audio files it would take 30 seconds to load. I wouldn't recommend Opus unless you're playing back on a computer, Opus is better than HE-AAC at every bitrate HE-AAC works at. If you send opus to your friends chances are they can play opus. Turns out bestaudio[asr=48000] is better than bestaudio[acodec=opus] for best youtube audio. You can generally get the best bang for your bitrate with x265 10-bit slower + Opus (128k stereo / 256k surround 5. However, I read that the highest setting of MP3 - MP3 320 CBR - isn't transparent, while apparently, Opus 128 kbps VBR is transparent for most people and "Opus 192 kbps VBR is indistinguishable from any original source for I was using AAC (Qaac q127). FLAC is like ZIP and compresses the file without losing anything; lossy compression methods such as MP3, AAC, OGG Vorbis, Opus get rid of some of the information using complex algorithms with the aim of not losing too much of Now as I'm testing, it's the FLAC 44. Opus is lower latency meaning it works better with less delay when using real time voice communication. 1 kHz -> FLAC 48 kHz conversion, that added the noise on top, what we can see in the OPUS files. E-AC3 is better than AAC but AAC saves marginal disc space compare to E-AC3, are you happy with the quality of AAC then I will encourage to go for it,if it's larger data to be placed in drive,you will end up saving some space,but quality won't be as admire as E-AC3 Never understood why 192kbps Is said to be transparent I can notice killer samples on Vorbis/AAC/MP3 that need over 256kbps. 1. Or check it out in the app stores FLAC vs AAC vs OGG loss comparison R2 So I made a comparison of FLAC, AAC (Apple) and OGG Opus vs AAC. No, . I just use libopus instead. Used ffmpeg to convert it to AAC, reconvert It to WAV (decompress it) and convert it to AAC again. Opus and Vorbis are comparable when encoded at higher bitrates with a slight edge to Opus. I'd say they should cluster by rater, and so for each set of comparisons (Apple AAC vs Opus11) they have a sample Opus is the future of lossy codecs, so don't use it to replace FLAC. Never convert lossy to lossy. But after that it really isn't better. If you see an AAC I think it’s usually safe to say it has been re-encoded. Or check it out in the app stores TOPICS. Opus is basically transparent down to ~100 kbps (subjective opinion, I hear very little difference, if any, between 96 kbps OPUS and FLAC, where most files below V0 MP3 contain noticable distortion), so it's great for portable use. The only two that are fully transparent to me at 192kbps are Musepack & Opus, It funny when Youtubers say "The audio compression is bad don't use It to judge sound quality" ignoring It uses 160kbps Opus. Opus seems to be the winner but I have no idea if you'd be able to hear the difference, I also don't FLAC vs Lossy compression (Opus/AAC/MP3 etc) After coming across this thread and using Opus as a daily codec of choice, I was curious as to how much information was actually lost when compressing from lossless audio. Only problems are compatibility and that Opus has not consistently beaten HE-AAC at the same bitrates. Introduction I made several listening tests in my life and at various bitrates (from 48 kbps lately to 190 kbps many Get the Reddit app Scan this QR code to download the app now. 500 conversion and mp3 compression at 50 conversion began to be very pronounced. To the point where a 256kbps AAC is comparable to a 320kbps MP3. Opus at 96kbps doesn't have parametric stereo, so both audio channels are 48kbps. Will be AC3 or AAC. opus files are ogg/opus, while . . Our ears are This chart https://opus-codec. Did they switch, or are the async vs live requirements different enough to use Opus 64kbps sounds better for me than HE-AAC 64kbps. AAC/OPUS 5. AAC is one of the standard lossy codecs for the audio portion of compressed HD video files & streams, so it is going to stick around for a very long time, for that reason alone. I tried it myself and got some remuxes and encoded the DTS tracks with AC3/MP3/Opus/AAC. AAC is definitely better than MP3, but Opus is even better if it is supported AAC with a good codec is way better than MP3, and not not much worse than Opus. MP3s and FLAC are fine. you may have to use mp3 There's two parts to every file: The CODEC (in this case AAC) and the container (defined by the file extension). opus is just a recommendation) and should be the default. 1 channels AC3/Dolby Digital is probably the most widely supported surround sound codec, AAC is commonly used for stereo tracks and should work fine on most devices. mkv -c:v copy -c:a libfdk_aac -b:a 128k Converted-AAC-Video. 3. It ran into some issues with dynamic range headroom so I bumped it up to 192 kbps. At least on iOS, if you're using bluetooth headphones, that OGG file is being converted to AAC in order for iOS to transmit it to your headphones, therefore there's quality and battery life loss. EAC3 vs AAC vs Opus . You're gonna want to use Apple's or Nero's encoder to get decent quality with AAC. And with surround sound they're just straight up abominable. YMMV Vid that I watched (for example) used OPUS at 512 (they said use about 100kbps per channel so 5. Here's an example of the comparison of a comparatively high bitrate mp3, a low bitrate m4a (aac) and a low bitrate ogg (opus). For a 5. so if you have some device like a mp3 player you want to play the file on or something you're going to want m4a. The bit rate of OPUS is up to 112, Whereas the bit rate of AAC is up to 144. mp4 or . Or check it out in the app stores FLAC vs OPUS vs MP3 imgur. If FOSS is the reason, there is Life is too short for aac. YT Opus of 131 kbps instead? Regardless, as pointed out by u/Drwankingstein, the problem is with the way YT creates the Opus audio. mka though that again might be any codec, same for m4a etc. 1 / Since yesterday I've been doing heavy ABX tests on 128kbps Opus vs others at 96 to 256k, It's pretty much the quality of 192 to 320kbps AAC/Vorbis/MP3. Plus we don't know what encode settings YT uses to create the Opus. The issue, though: While Opus has good uses, I don't see any of them as particularly relevant to music - MP3 and AAC are much to ingrained on the "file" side of music, and I don't see any of the major streaming vendors switching from MP3, AAC, Ogg or FLAC/ALAC. Saying Opus is better because of it is the same as saying that 480p is better than 4k because it uses less bandwidth. They should sound effectively the same. Additionally, Opus is not always the best option for music. In the past it would transcode AAC 5. I believe it's still more efficient than at least AC3 if not EAC3 also and again supports 7. The point was that having Opus available as on option on Some devices seem to do better than others at decoding AAC; Android seems to have a poor reputation when it comes to AAC for some reason. 1 It'll probably transcode it down even if you have it. Normally, I'd just go for the Opus since it seems to obvious choice. Opus support has increased wildly since then. I've been using HE-AAC for years for portable music / streaming from Plex. Plus Opus is free and apparently the future. I've been watching and playing with Opus for a while. EDIT: I should note that Opus isn't really intended to replace those kinds of files, but it does happen to sound better than them. 1 channels, the TV will pass the sound to your sound system as PCM). r/DJs A chip A close button. Hi, Opus WAV The 64bit versions of LAME and OGG/Vorbis are in "\foobar2000P\encoders\64bit versions". they are kinda different. SBR is hackery way of faking high quality audio by transposing up harmonics from lower frequencies into the high frequencies (intended for If compatibility isn’t an issue, then use Opus instead. net bitrate is going to be about the same (I define "net bitrate" as View community ranking In the Top 10% of largest communities on Reddit. I've looked high and low for transparency comparisons of AAC vs EAC3 using FFMPEG. 300 kbps AAC vs Lossless Compared to the video data it is being combined with, it's all a wash when it comes to audio codec comparisons. Do keep in mind, you'll lose some sound quality by AAC is objectively a better quality audio codec than Ogg Vorbis especially at lower bitrates. AAC was a state-of Most humans can't tell 320kbps AAC apart from an uncompressed file, assuming they came from the same master. Opus definitely beats HE-AACv2 with stereo separation and highs, and the bass is more deep and warm with opus, at least to me. When digital TV came in, you either got it or got garbage with digital artefacts or nothing at all. AAC/OPUS were great in 2005. Eac-3 vs. That said, MP3 at 320 kbps is still a reliable classic.

At 15 kHz, there's some additional noise in the Compatibility will improve - MP3 and AAC are nearer 20 years old where as Opus is barely 3 and has all the resistance of pre-existing, mostly adequate formats to deal with. Your purchased AAC files are ordinary AAC-LC format and are as good as they can possibly be. if you encode 400AAC with HE-AAC and check it in a spectrogram you will found out that it removes everything above 16khz~ (where it's harder to tell the difference) and uses all that bitrate for everything below that frequency. So, as @Tetsujin mentions, the best one would be the one that is Opus the best or is there something even better? Since you can't hear the difference the issue isn't which audio codec is best. That said, my soundbar is dying and sub cut out so, not a great test. Opus was at ~32kbit while mp3 at ~192kbit (both VBR and mp3 with -joint_stereo option as I recall). If you just want to convert it to a regular m4a (non lossless) then change alac to aac or libfdk_aac. I'd imagine that .

OPUS is better for lower-rate music, While AAC is better for classic music. However encoding formats such as DTS (which contain fancy spatial audio metadata) to opus, AAC or even FLAC is not recommended as these formats have no support for said metadata. I didn't opt for AAC as its not widely supported. when I do promo videos, I usually do mp4 with aac, as I've run into size issues with . so you could do a . This makes it suitable for immersive audio experiences, such as surround sound and virtual reality applications. They can only stay the same or go down. If you want maximum compatibility for 5.

You must have a combined karma of 40 to make a post, and your reddit account must be at least 30 days old; this is to prevent spam Can you play 128kbps AAC on clubs and smal festivals? Skip to main content. So to me, it comes down to compatibility with your hardware. But since 258 and 338 have a higher bitrate, so youtube-dl goes for them over 251. The quality vs. For me, it makes sense to switch to AAC since Spotify is doing a lot of under the hood stuff preparing for the Hi-Fi release. But yeah it’s quite rare in the wild. For example if you wanted to convert the files to AAC you could just do this: ffmpeg -i Original-DTS-Video. Ogg is the Get app Get the Reddit app Log In Log in to Reddit. opus, Whereas AAC is . I see in my transcoding settings: Quality for bitrate: AC3 < AAC < Opus. So your choice between m4a and opus should be primarily about compatibility. But, when I compare the two, I find It is usually contained inside an MPEG-4 container (. If any players actually supported it. I've been using 256 kbps Opus for a little while but didn't realize how remarkably efficient Opus is for compressing audio. Reviews. HExAAC isn't mature enough to compete with opus, cause of transparency and AAC LC , I have no reason to use that anyways. I've never seen anything transcoded to AC3 and I'm pretty sure every client I have supports it. The fact that it offers better quality at comparable bitrates is just an added bonus. "ffmpeg -i source -c: a libfdk_aac -b: a 128k target" but I don't have libfdk_aac in my Debian. ogg flac will be better cuz of the loseless, although the file size is still large. Unless you have specific compatibility needs, Vorbis is deprecated and it’s successor is Opus. What happens behind the scenes is that YouTube recommends its artists submit files as AAC in an M4A container and then converts all submissions to 128k AAC (LC) in an M4A container. They don't do multichannel AAC so it's not an option for me. Opus is currently the most advanced lossy codec around. Then repeated the same experiment with mp3, OGG Vorbis and opus. 1 use 512) and just started testing and seems smaller than e-AC3 640 and with my current setup sounds the same. org/comparison/ shows that above 128 kb/s opus, aac and mp3 are very close in terms of quality. Also please give a good/best config to use for OPUS at 96kbps or 128kbps -c:a libopus -b:a 96k -ac 2 for stereo. Even on good equipment I think you'd have a hard time spotting the difference between Opus and FLAC. I've used YTM for a couple of years now, and upload my own music as well as stream others. mp4 or sometimes . OPUS Vs AAC | Difference between OPUS and AAC. Compatibility: Opus < AAC < AC3. They u/bastawhiz finally a recent 2017 detailed analysis so rational, chicken and the egg of AAC and Opus, with many sources (plus great Oatmeal comic), basically Mono instead of Joint Stereo to avoid unnecessarily wasted bits, and using VBR correctly (min and max at what you'd consider for CBR anyway, like 64-128kpbs Mono) and would be hardly AC-3 is the native codec for most audio on discs and digital store downloads I think. aac or . When every other music streaming service uses lossless or AAC now, but Spotify uses a 20 year old audio codec called Ogg Vorbis which no one really uses for audio compression purposes, there must be a really good reason. AAC (iTunes)-> AAC (bluetooth) will almost always result in less artifacts/noise then Ogg Vorbis (Spotify) -> AAC (Bluetooth). 20 times. I recently turned on the stats for nerds and see that my uploaded music is playing at 141 mp4a, and the streamed music is playing at 251 Opus. mkv I mean, it's often the people with older MP3 players, or even car stereos that do MP3 CDs and similar things are probably more likely to be pirating than smart phone users anyway - since there's generally no music subscription services for the older gear (and most of the music played on those smartphones is from such services). In other words, the changes that were made to the audio in order to get it to fit in a relatively tiny AAC file are irreversible. Multichannel support-OPUS supports mono and stereo audio, as well as multichannel audio. Presentation, documentation, comparison with other formats, download links, source code These are the results of ABC/HR tests Is it not possible to convert aac/mp4 to opus/mkv and still have the audio and video synced? I tried setting async 1, didn't work, the audio was much shorter or longer according to ffrprobe. It sounded better. Other than that, AAC and Opus should both be YT's Opus uses SBR (Spectral band replication). ogg vorbis vs aac comparison, but I don't know off the bat which would be better. I I would either need to just use the m4a files, use the opus files (but then I'd miss out on the MixedInKey automation), converting opus files to flac which uses lossless compression) which results in rather large file sizes and it seems kind of silly to pretend you have a lossless compression file so it doesn't quite sit right in my head, or converting the opus files to m4a 128 kbps Opus file vs a 320 kbps MP3? The Opus one is usually gonna sound better, even though the bitrate is lower. I doubt AAC will gain popularity as a music collectors' format. As in, would win in a double blind test, every single time. You deflected the point, and MP4 isn't confusing anyone. Due to Itunes being 256 AAC since forever the producers mastered it to fit that format with the compression. 1, but it isn't doesn't have the same level of compatibility as traditional AC3. I can hear it easily when listening at home alone on my reference grade system. What is the difference between these two? Is one significantly better or worse than the other? Folks who play chess will understand my analogy - the difference between MP3, OGG, AAC et al is about the same as between computer chess engines. (I used the standard ffmpeg codec for these convertions) the results were very interesting. The open source MP3 encoder "Lame" improved to the point where it is now the dominant MP3 encoder, and is competitive with AAC encoders - indeed, it's better than the open source AAC encoders at same bitrates, though the limitations of the MP3 format keep it from matching the good AAC encoders at medium bitrates. Its great quality at seriously low bitrates and very low latency are just added bonuses to it's fantastically permissive licensing though. The question is if AAC/AC3 is better than an OPUS transcode that would be the result. For higher bitrates it seems the Nero AAC encoder on a constant bitrate has the best results, from last I If you're not space constrained just go high and stick with 320kbps. 1 soundtrack, I'd bet my shoes that 512 kbps AAC (FDK or qaac, your choice) or 512 kbps opus can both hand DCA its ancient ass, with ease. I believe HE-AACv2 uses parametric stereo, so the stream is 96kbps, acting like a mono stream. AAC - Melomania 1+ So i suppose i could better start using the OPUS format from now than right? and no, i will not convert my MP3's to OPUS haha, that will basically be compressing compression haha, i have this program that allows me to download music from the internet in various formats, including FLAC, but that just takes up way to much storage space from my phone, so thats why i always Get the Reddit app Scan this QR code to download the app now. Internet Culture (Viral) Amazing Youtube premium opus 251kbps vs Youtube music mp4a/aac 141kbps . But if I check the developer options it is playing using Opus all the time (mp3 I myself checked what was happening with Opus and MP3 - in the end, Opus maintained a pleasant quality until ~100 conversions, and MP3 "lost its sound" by approx. OPUS smoother bit rate and AAC suffers bitrate starvation. Browser audio quality, AAC, MP3 or Opus? Does anyone I doubt it matters as it sounds decent enough. Also some stereo instruments are not enjoyable anymore. Which is good If the source is 16bit FLAC. Use it to replace MP3s, Ogg Vorbis, and AACs (although don't convert from them if that's all you have for those files). However, whenever I play flac songs, Plexamp says Opus 128kb, but if I look at my plex Dashboard, it says its direct playing FLAC. Opus supersedes vorbis and yes, foobar's converter is good enough because if you convert something with it and check the metadata, it should tell you that it's been encoded using the latest libopus release 1. 1 if you want it. AV1 and Opus are both free for anyone to use for any purpose and are more widely supported than any other decent modern codec (excluding older, less efficient but faster ones like H264 and VP9). By the way what you're asking about is Vorbis vs Opus, not Ogg vs Opus. 1 to AC3 (as AAC is not supported by my receiver) and I would get proper surround, now with this OPUS transcode my receiver is doing Pro Logic. Review What are your thoughts on xHE-AAC I'd like to see it take off because it's way better than even opus at 8kbps, but I'm concerned about the digital radio applications. In general, AAC has slightly better support than OPUS across browsers and devices, but OPUS is a license-free codec and as such probably the morally better one. Results are now totally outdated. if you're just going to play it on android or computer, you can play opus on those I have ABXed Vorbis vs Opus and, at 256K couldn't tell a difference. That said it is about equivalent to around 192kbps Opus, or 256kbps AAC/Vorbis. Especially when the only very slight benefits of VVC and xHE-AAC come at a massive cost of their ultra-proprietary nature. Ldac vs aac on YouTube is nothing since YouTube’s audio quality is below the max bandwidth of aac. com Open. In plexamp, I set the max bitrate to 320, and the conversion to 128kb opus when its FLAC. The multichannel Opus format works on Windows PMP which is why I use it! Otherwise the DTS passthrough track is there for my theatre use. It's really best to use the formats as-is without converting Although Opus often performs better than AAC when encoding from a lossless source, in Youtube's case, it's much more likely that the original audio that was uploaded to them was in AAC format to begin with - simply because it's the default recording format on pretty much all devices, and their upload guidelines request it. When I choose AAC as support for Opus was lacking at the time I was doing ripping, but that was before Plex and realtime transcoding. Even if iOS is doing a decoding/encoding step in between, for example when mixing in other sounds, AAC as a codec is very stable. But I dont have a home theater so opus is fine for me. Tricky question as audio subjective quality depends on encoder quality - simple AAC encoder may deliver sub-optimal Opus is a great format and would be a fine choice. If iOS is passing the AAC stream directly to BT, there is effectively no loss involved. e. ogg-flac. 1 or 7. A Session In The Abyss: xHE-AAC vs OPUS at 12, 24 and 32 kbps (voice & music) 2021-05-16 21:12:48.
