I've just started using blender to edit videos (a site recommended it out of a list of free video editors), and for the recordings, I've been using a third audio channel to help separate my speech from the rest of the audio. However I'm not sure how to edit it in blender and i haven't found any tutorials on how to do this. Is there a way in blender or would I have to use another program to edit the audio?
EDIT: to clarify, when recording, my voice is recorded into a third audio channel along with the usual left and right channels in the video file. this was so I could edit out background noises (or me coughing in some cases) without having to mute all sound. For now i'm using a "push to talk" button to reduce background noise
