Convert Stereo Audio to Mono
Mono is enough for speech, lectures and podcasts, and it fixes recordings where the voice is heard in one ear only. Both channels are mixed together, so nothing is lost.
A mono MP3 is also about half the size of a stereo one at the same quality. Files are deleted from our server automatically after 48 hours.
