CELT/Opus Codec
vinnie97:
From the makers of Vorbis come this newish ultra-low bitrate codec:
http://celt-codec.org/
This one performed impressively in the recent 64kbps listening test at HydrogenAudio:
I'll assume this one is not supported in the latest public release of Rockbox (I haven't experimented myself yet, just discovered this little known codec), but I hope it's being explored for the future.
Llorean:
It's not supported, but it's really not a good idea to post things here without at least checking first. It's quite common that people bring up an idea for something that already exists within Rockbox.
It also wouldn't make much sense until the codec reaches 1.0, since a changing bitstream means old files will lose compatibility.
vinnie97:
I'm sorry, sorry. I *just* read on the CELT site that new versions would likely break backwards compatibility and was about to amend my post to state that (I also did a forum search to see if it had been brought up in the forum previously, as I always do before posting).
I did look in the codec lineup in the FAQ before posting and did not see it but posted on the off-chance that a daily build of recent might have added decoding capability (before reading about lack of bitstream backwards compatibility).
halonachos117:
I, too would like to eventually see Opus supported. It seems nearly complete now. Of course, there's still the possibility that they may need to rewrite a good portion of it, but I think it's still a good idea to look into (eventually) writing a codec.
saratoga:
I doubt they would make huge changes to the decoder now, so if someone wanted they could probably safely port it with only minor effort needed to sync future improvements.
