so i made a little chip music floppy release to test out the new codec. i'd say 20 kbps vbr is still a stretch from acceptable audio quality but still lightyears better than any other existing codec.

likes!

so, a first quick test:

Reference WAV, 48000 Hz Resolution, 440 Hz tone

OPUS, 64 kbps VBR, recorded via internal mixer (sorry, was too lazy to adjust the volume)

I'd say even at 64 kbps it looks pretty good, though it isn't perfect. But there's a ton of settings available with the encoder, I'll be checking those out later.

Yeah, that'll be interesting. I suspect it to be a problem of the FFT algorithm though, so I don't know. Maybe there's some magic special code for squares in it. I think I'll pit against my previous low rate test, that example should be still around. I'm not on my own computer atm, so I'll have to do that later.

latest version of firefox (which i have, sadly) already supports it i believe

and latest version of foobar (which i don't have) as well

I'm pretty sure there's an HTML5 <audio> tag on this page:

http://www.opus-codec.org/examples/

HTML5 does not provide support for specific audio codecs. The HTML5 Audio module just provides an audio wrapper that can serve audio content. It's up to the browser makers to determine which audio codec formats they will actually support.

This means that it really doesn't matter if HTML5 supports it or not, it's a moot point.

Dunno if HTML5 supports it yet. That'd be big.

Yes it does. According to my research, Opus should work in the latest versions of Firefox, Chrome, and Opera. Also VLC started supporting it in version 2.0.4.
And Rockbox is going to support it, meaning it will be available on a wide range of upcoming portable devices.

I'll upload a little HTML5 test page in the coming days.

That is pretty cool! I hope it doesn't end up like OGG; where it is technically quite nice, but finds little use outside of enthusiast or technical communities, and has little to no hardware support.

OGG (and CELT for that matter) are used in tons of games, it saves having to pay license fees for other codecs.

wow, this is pretty damn exciting! This'll make it easier to share things across the net without compressing it to all hell (which drags on my low bandwidth speed like you would never believe).
thanks for sharing, ub!
