opus 256 = mp3 320?

Recommended Posts

This is the first time I've heard of this format but from some quick research I've found that, yeah, opus and mp3 at 320 are pretty much identical. The big difference is more apparent at lower bitrates, where opus outperforms pretty much every other codec in terms of perceived quality. This is because it was designed specifically for telecommunication applications like VoIP.

The other main difference is in algorithmic latency (the time it takes to decode the compressed file). Opus latency is ~20ms using default settings, but can be tweaked down to ~2ms, while mp3 latency is over 100ms, this is one of the reasons why opus is so good for sync-critical applications like real-time communication, live lip-syncing and networked performances.

Personally I don't really see much of a use for this codec for applications like djing, since the issue of algorithmic latency is eliminated by decoding the entire file into RAM when a song is loaded in a deck. There's also the issue of compatibility, I don't know of any DJ software or hardware that is compatible with opus. I could see it being useful for mobile playback, having better quality reproduction at lower bitrates (smaller file size), but storage limits of phones doesn't really appear as an issue lately. I'll be sticking with my current choice formats of WAV/FLAC/AIFF/MP3 320, they all work just fine for my purposes.

I haven't done any actual testing though so this is all just speculation off of info from blind listening studies and the specs given by the devs. I'd be interested to hear@Ganjastep's view on the subject.

@IIIu6ko @Xplosiv @Hazl 

Well just based off what I see in those SPEKs above, MP3 is the superior format

here is why, OPUS-256 has;

I'll explain more later, gotta take off for a bit

@HazlThe problem is that OPUS ~ 256 can be downloaded from YouTube. And if it is almost no different from 320 mp3, then what's the point of waiting for release in stores?

This is no longer 192 and not even 256, it is already very close to what you can buy in the store. (talking about 320 mp3)
