Use one channel for one-sided speech
If speech appears only on one channel, keep that channel rather than averaging it with silence. Mixing opposite-phase channels can cancel sound. The export is a new 16-bit PCM WAV; your original file is unchanged.

FAQ
Does this upload my recording? +
No. This tool processes the file on your device. There are no audio uploads or server processing charges.
Will stereo to mono improve audio quality? +
It changes channel layout, not recording quality. It can fix one-sided playback, but cannot remove clipping or restore missing speech.
