CELT audio codec 0.5.1 (Default branch)
CELT (Code-Excited Lapped Transform) is an ultra-low delay audio codec designed for realtime transmission of high quality speech and audio. This is meant to close the gap between traditional speech codecs (such as Speex) and traditional audio codecs (such as Vorbis). License: BSD License (revised) Changes:
This release fixes a number of issues with 0.5.0. Several cases where the encoder could fail have been fixed, including one that could cause memory corruption (and possibly a segfault). In addition, the VQ search has been improved, which results in a small CPU usage reduction, while fixing some quality problems with low frequency tones. Other than that, there should be no significant quality changes. Image

audiocfg

AUDIOCFG(1)						    BSD General Commands Manual 					       AUDIOCFG(1)

NAME

     audiocfg -- configure default audio device

SYNOPSIS

     audiocfg list
     audiocfg default index
     audiocfg test index

DESCRIPTION

     The audiocfg utility helps maintaining the audio and mixer device symlinks.

     Run with ``list'', it lists the available audio devices and shows the currently selected default audio device.  Called with ``test'', it
     plays a tone of 2 seconds for each channel of the device with the index index.  Called with ``default'', it sets the default audio device to
     the one with the index index.

     audiocfg needs access to /dev/drvctl and write access to /dev (when used with ``default'') to work.
