  Description     : The CELT low-latency audio codec

 CELT is an experimental audio codec for use in low-delay communication.

 CELT stands for "Code-Excited Lapped Transform". It applies some of the CELP
 principles, but does everything in the frequency domain, which removes some of
 the limitations of CELP. CELT is suitable for both speech and music and
 currently features:

  * Ultra-low latency (typically from 3 to 9 ms)
  * Full audio bandwidth (44.1 kHz and 48 kHz)
  * Stereo support
  * Packet loss concealment
  * Constant bit-rates from 32 kbps to 128 kbps and above
  * A fixed-point version of the encoder and decoder

 The CELT codec is meant to close the gap between Vorbis and Speex for
 applications where both high quality audio and low delay are desired.


It is currently quite experimental still, both the bitstream format
and the API are subject to change at the present time, but the upstream
authors are ready for people to begin trialling it in real use situations.
It is claimed to already outperform the alternatives for the use cases that
it is optimising for.

Cheers,
Ron
