How to convert audio that is recorded with a monaural microphone and has sound only from the left side to monaural, or how to switch the left and right channels

Question

When I check what was recorded in monaural, it was recorded only in stereo 1ch (Lch). Also, there is audio that was recorded incorrectly on the left and right. Is there a way to convert mono audio to stereo or swap the left and right channels?

Answer

Use Stereo Fixer to record with a monaural microphone and convert stereo 1ch (Lch) audio to stereo, or to mix stereo 1ch (Lch) and 2ch (Rch) to monaural. is best.

As will be described later, the method of converting tracks that are often seen on the Internet to Mono requires a track dedicated to Mono, but with Stereo Fixer, it can be set for each clip, so it can be set in the stereo track You can arrange the target clips in .
