What this conversion produces
Create a mono version of a two-channel WAV recording for an audio workflow that expects one channel. Each output sample is the average of the left and right source samples, avoiding the doubling in level caused by simply adding channels. The output uses signed 16-bit PCM and retains the original sample rate. Mono input can also be normalized to the same output format.
Supported input and practical limits
Supported sources are uncompressed RIFF/WAVE PCM with 8-, 16-, 24- or 32-bit integer samples, or 32-bit IEEE float, with one or two channels. MP3, AAC, WAVE extensible, compressed WAV and RF64 are not decoded. Invalid non-finite samples are rejected. Input and output are capped at 4 MiB. Averaging phase-opposed stereo channels can reduce or cancel sound, so listen to the result before replacing a source recording.
What should I know before converting?
Supported sources are uncompressed RIFF/WAVE PCM with 8-, 16-, 24- or 32-bit integer samples, or 32-bit IEEE float, with one or two channels.
Is input uploaded?

No conversion history is saved. The converter does not upload files to a third-party conversion service.
