With Wavosaur it’s possible to process a channel, without affecting the other channel, for example, you can change the volume on the left channel without changing right channel on a stereo file.
1) launch Wavosaur and open an audio file, for this exampe, we also made a selection on the file.
2) on the left of the Waveform right click on the dB bar of the channel you want to be unchanged , a menu will pop : choose “Deselect”
3) the channel that is “deselected” appeard “grayed” , on the following picture, the left channel is deselected :
4) now if you apply a processing effect on your file, only the right channel will be affected :
on the picture you can what happens if you apply a Process->Mute
Of course, if you apply a processing that change the length of the file, the two channels will be affected, regardless of the selected/deselected channels
