Questions
How does the karaoke effect work?
It removes what is identical in the left and right side, which is usually the lead voice. It works well on some songs and not at all on others, and the bass may get thinner.
Why make a file mono?
Mono files are smaller and sound the same on a single speaker, a phone call or a podcast.
