How to process only one channel

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

    Pro Tip: You can also press the number 1 and 2 on your keyboard (not number pad) and this will toggle select/deselect for each channel.

    I have 2 stereo files. one file is a drum track I wrote. The other file is a bass guitar track I recorded to go with the drum track. I want to combine them. I cleared the left track of the stereo Bass file, and cleared the right track of the drum file using Process>mute. I was using deselect at the db bar to keep from muting both tracks of each stereo file, Then I copied the right track of the bass & paste into the empty right track of the drum file. Even though the left track of the drum file was deselected, the paste overwrote the deselected drum track. I got a stereo file of the bass> I used Edit>undo to go back to what I started with. How do I prevent paste from overwriting a deselected track?
    I tried this method because I was unable to PLAY the drum track AND RECORD the Bass track at the same time. I got around that by playing the drum track on another computer(listen with headphones) and record the Bass track on this computer. Then clear the required stereo tracks to get a “mono” paste. I realize that once pasted I will have to play around with silence insert ,or Cut. to get them in sync.
