Check before mixing

A quiet right channel can mean the microphone was recorded only on the left. Strong negative correlation can mean phase cancellation. Averaging the channels may erase speech, so listen to each channel before choosing an export.

FAQ

Does this upload my recording? +

No. This tool processes the file on your device. There are no audio uploads or server processing charges.

Does a silent channel mean the file is broken? +

Not necessarily. Some recording setups intentionally put a microphone on one side. Exporting that channel to mono can make it play evenly on both speakers.
