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:|

This also turns off audio playback. SUPPORTED MOVIE FORMATS
Main purpose of this utility is to playback movie files recorded by xawtv, motv and streamer. It should be able to playback every AVI or QuickTime movie written by one of the mentioned utilities. Feel free to submit a bug report if this doesn't work for some file. QuickTime pia uses libquicktime to decode quicktime movies, thus it should be able to decode and playback all movies with codecs supported by libquicktime. AVI AVI support is very limited. Video: uncompressed RGB data (15 and 24 bpp) and mjpeg is supported. Audio: only uncompressed PCM data works. WAV WAV files are playable too, with the same limitation like AVI audio: only uncompressed PCM data. AUTHOR
