Spectro-Edit 0.2 (Default branch)
08-10-2008
Spectro-Edit reads in regular PCM audio files,then shows the audio visually in a time vs.frequency plot. The fun part is that you can"paint out" any part of the visualization and playback the audio subject to your modifications. Whenyou are happy with the result, you can save yourwork back to a WAV file. This could be useful forpodcasting (edit out microphone noise, chairsqueaks, phones ringing, and other backgroundnoise), music (make strange and unusualmodifications to the sound for artistic reasons),research (visualize animal calls or noisepollution from nearby industrial activity), andgeneral purpose geekery (which was the originalpurpose).License: GNU General Public License v3Changes:|

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. FILES
