Please include support for Opus codec.  It was on slashdot so it must be good.

Thanks!

This would be very preferable.  AFAIK, nothing else really beats it.

OPUS is now standardized in IETF RFC 6716.

Additionally it has been declared one of the two mandatory audio-codecs for 
WebRTC (OPUS and fallback to G.711 for PSTN-compatibility).

It can handle packet-loss up to 30% with very few distortions.

It also provides G.711-quality-mono at 8 kb/s and HIFI-Stereo at 48 kb/s (20 
kHz bandwidth).

You can even use it for Video-on-Demand with surround-sound (up to 255 
channels)! ;-)

Specs:
    Bit-rates from 6 kb/s to 510 kb/s
    Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband)
    Frame sizes from 2.5 ms to 60 ms
    Support for both constant bit-rate (CBR) and variable bit-rate (VBR)
    Audio bandwidth from narrowband to full-band
    Support for speech and music
    Support for mono and stereo
    Support for up to 255 channels (multistream frames)
    Dynamically adjustable bitrate, audio bandwidth, and frame size
    Good loss robustness and packet loss concealment (PLC)
    Floating point and fixed-point implementation

See http://www.opus-codec.org/ for information and 
http://opus-codec.org/examples/ for sound-samples!
