- TylerE 6y agoI have never seen an Opus file in the wild. MP3 and FLAC are by far still dominant. Ogg is still popular I. It’s niche (eg game sounds, and I think Spotify uses it too)
- prvc 6y ago>I have never seen an Opus file in the wild. You have likely heard one. For instance, if you are a Youtube user.
- tinus_hn 6y agoOn the website? Can browsers natively play them?
- nullc 6y ago> On the website? Yes, it's one of youtube's standard audio formats. > Can browsers natively play them? Yes.
- est31 6y agoMost browsers can play them, except for Internet Explorer and Safari for the mode you usually want to use (webm or ogg container). https://caniuse.com/#feat=opus https://caniuse.com/#feat=opus
- gruez 6y agoIs there a reason why mp3 is still around? AAC has better compression ratios, and support is a non-issue. Maybe mp3 has better brand recognition? Most people know what a mp3 is, but probably wouldn't know what AAC or a .m4a is.
- lozf 6y agoThe roll-out of AAC (which was designed to address the problems with MP3, but was not backwards compatible) was slowed a bit by expensive licensing fees for hardware manufacturers and the lack of a good free encoder (though there were some very poor implementations)... By the time this was sorted MP3 had gained massive popularity on "teh scene" and was soon followed by napster etc - the rest is history, so yes it's all about the "brand recognition" now sadly. Most people could have a better sounding music collection in about half the size required for MP3 safely... still at least disk space is cheap these days. The unfixable problem of MP3s "shortest allowable blocksize" causing audible smearing on transients will be with us until the format is abandoned, but I won't hold my breath. These days for the best quality lossy audio you want AAC-LC encoded with either Apples encoder or the open source FDK-AAC by Fraunhofer (developed for Android) but fully cross platform... or Opus for a completely free and open codec , but still not yet as widely compatible.
- jumelles 6y ago> massive popularity on "teh scene" More than that - scene releases required MP3 (LAME V2 IIRC) to be used.
- p1mrx 6y agoMP3 has been around so long that it works with damn near everything, and the last patents expired in 2017, so it's now a completely free and open standard. If you don't care too much about file size (LAME -V0 is ~256 kbps), it's a decent option for many purposes.
- brnt 6y agoThere are no quality open source AAC encoders like there are for MP3.
- knaik94 6y agoWhatsapp audio messages are encoded in opus.
- est31 6y agoOpus files are often enclosed in the Ogg container format, so some of your .ogg files might actually contain an opus stream instead of a vorbis stream. Files with an .opus extension usually use Ogg as container format as well.
- xellisx 6y agoI was originally thinking of Ogg Vorbis....
- marcan_42 6y agoOpus is used by basically every company with an integrated product that they control, who doesn't own patents for inferior formats. That includes basically ~all VoIP software, games, YouTube on Chrome and other supporting browsers, messaging apps with audio features, etc. Basically anyone whose main business isn't audio. Because it's the best codec and it's free. It's be dumb not to use it. And if you control your entire product, you can just add support and use it without worrying about compatibility. Unfortunately, the companies whose business is audio invariably have some sort of relationship with patented, shittier formats like AAC or even more obscure stuff that only exists to collect royalties like aptX, so they aren't going to market Opus to you as a consumer of audio formats or a feature in audio related products, nor promote support and compatibility across devices. And so you pay more, and get an inferior product :-)
- duskwuff 6y agoAlong with YouTube audio, it's used by Discord for voice chat.
- lozf 6y agoAnd all WebRTC based messaging: Hangouts, Teams, Signal, WhatsApp, Messenger, Skype, etc.
- jimmySixDOF 6y agoSkype default codec is SILk
- deleted 6y ago[deleted]
- lozf 6y agoSorry, yes - Opus combines SILK with CELT was the source of my confusion.
- throwaway189262 6y agoIt's supported by video container formats and widely used. You've probably heard a ton of it watching videos online. Virtually every video chat system uses it. Hangouts, Zoom, WhatsApp, etc
- JoshTriplett 6y agoOpus is the standard audio codec in WebM, alongside VP9 or AV1 video.
- prvc 6y agoAV1 does not appear to have been added yet
- prvc 6y ago... as far as this source is concerned at least: https://www.webmproject.org/docs/container/#video-codec https://www.webmproject.org/docs/container/#video-codec
- p1mrx 6y agoIt's one of the WebM audio codecs; Vorbis was first.
- xellisx 6y agoThinking about it, I got confused and was thinking about Vorbis. D'oh!
- powersnail 6y agoMy experience of using youtube-dl is that the best audio format to download from Youtube and Youtube Music seems to be opus usually. So, even if people don't consciously choose opus, they probably listened to opus files quite often.
- indolering 6y agoOn virtually every platform where trademarks and patent trolling isn't the norm. So you won't see it being advertised because Dolby/Apple/Samsung isn't making money off of it.
