: HTML5 Audio: Which formats? Ditch Ogg Vorbis in favor of Ogg Opus? Is MP3 still needed? I'm currently working on a website which has to stream audio files. Since bandwidth is always an issue,

@Martha676

If you target only HTML5 you cand go safely without MP3, but if you want also backward compatibility you may need it.

MP4 AAC is the best choice. You can go also with WebM format to cover what is not covered by MP4 AAC.

OGG Opus is still not supported on other browser than Firefox bu it will probably be, since everyone wants to follow the standard.

Of course nothing beet in support and quality WAV format, but then the size matters if the bandwidth is a problem.

Speaking more as a potential user of your site than as a webmaster, I'd say stick with MP3 for now, for two reasons.

First, unless you're expecting to serve only geeks who aren't put off by words like codec, or you're sure all of your visitors will be using the latest and greatest browsers, I think it's better to ensure that for the average visitor, things will Just Work.

Second, my sense is that MP3 quality (of sufficient kbps) is fine for people listening with computer speakers or earbuds. You can always provide download links to superior quality options. For the audiofiles. ;)
