Convert WAV to mono

Upload a WAV file and mix it down to a single mono channel.

Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.

Half the channels, half the size

For uncompressed WAV the arithmetic is exact: mono is half the size of stereo at the same sample rate and bit depth. Both channels are mixed into one, so nothing recorded only on the left or right disappears.

Standard reasons

Transcription services price and perform better on mono. Telephony systems require it. Field interviews recorded in stereo with one dead channel become clean centered mono. Speech datasets for machine learning are conventionally mono as well.
