edit Channels apart

Is there anybody who can explain how I can edit channels apaart? the left channel sounds to week in opposit of the right channel

Yes, you can do that from the Track Control Panel at the left of the track

  1. Click on the little black downward pointing triangle to get the dropdown menu
  2. select Split Stereo Track
  3. the channels are now separated and you can select and manupiplate them independently
  4. when finished, joint the two channels back into a stereo track by clicking on the little black downward pointing triangle of the top track
  5. select Make Stereo Track

See this page in the Manual: http://manual.audacityteam.org/o/man/audio_track_dropdown_menu.html

BUT if all you have is an imbalanced recording and you want to even up the channels then there is a much eaier way to do it by using the Normalize effect and checking the box that says Normalize stereo channels independently

See this page in the Manual: http://manual.audacityteam.org/o/man/normalize.html

But better still to fix the problem at source so you are feeding Audacity a balanced signal.
