Note that's it's not especially well-tuned for 8 kHz audio; most<br>people use it at 48 or 44.1 kHz. It will work though.<br><br>You might also be interested in the new Opus codec we're developing.<br>It's somewhat higher complexity, but offers superiour compression and<br>the reference implementation includes a fixed-point encoder, which may<br>make up for the complexity difference on
