I was wondering, if someone has already played around with Codec2 by David Rowe.

The codec delivers impressive quality at 1500bps. I wonder what container I should use for archiving, as I don't have an interactive software that uses Codec2 right now. I wonder how I can run some tests with it, as I don't know of any decoder software right now.

Anyways, would be nice to know if this actually got any public exposure at all.

Still under heavy development. So, talk about archiving or any serious deployment is still early IMHO.

This might interest you, from the Opus/CELT guy:

Well I certainly know Codec2 is early development. Then again, Opus isn't quite finished as well...

Since both don't have minimal bitstream containers, and they're not supported in any existing container, it's quite difficult to do some exemplary testing. All I know, is that it looks really promising, and all. I just wish, development would hurry up a little. wink.gif

You can test Codec2:
http://www.rowetel.com/blog/?page_id=452#quickstart

Just look at the script dir and replace the included test files with your own.

Opus is ready(1) from a technical POV. It's just stuck in bureaucratic and legal bullshit. It already has container support(2) , reference encoder/decoder tools(3) and even an excellent (even if flagged experimental) TVBR mode in the reference codec(4).

It's actually on alpha (if not pre-alpha) stage and hardly usable.
