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:|

DBCAT(1) General Commands Manual DBCAT(1) NAME
dbin - Connect sound card input to DB Fourier Synthesis daemon SYNOPSIS
dbin [options] DESCRIPTION
The dbin tool allows to connect a sound card's input channel to dbfsd. Both dbin and dbfsd are part of the DBMix project, a digital audio mixing system. dbin is needed to mix in data from a microphone, or from an external audio device plugged into the line-in jack. The audio device used by dbin must support full-duplex operation. Also, this device must not be used for the master or cue output of dbfsd. Otherwise, dbin will output but an empty audio stream. OPTIONS
-8 Input data comprises of PCM-coded 8bit unsigned samples. (Default: 16bit signed samples.) -a dev Connect to audio device dev. (Default: /dev/dsp.) -c n Connect to channel n of dbfsd. (Default: first channel available.) -d Print out debug messages to console. (Default: debugging disabled.) -h Print summary of available options. -l Audio input is a line-in source. (Default: input is a microphone source.) source.) -m Input data is a mono stream. (Default: interleaved stereo stream.) -r rate Input data is sampled at rate Hertz. (Default: 44100Hz.) -s Send output data to stdout. (Default: Send output to dbfsd.) dbfsd. SEE ALSO
