Split stereo audio into left and right mono files
Karaoke stems, language-learning duets and old interviews hide different content on each side — but downmixing to mono blends them back together. A true channel split hands you L.wav and R.wav as separate lossless mono files, each playable and editable on its own.

Frequently asked questions
What is in each file?
Exactly the original left or right channel as 16-bit PCM WAV — nothing summed, nothing discarded.
Does it accept mono files?
No — there is nothing to split; the tool rejects non-stereo input instead of duplicating the channel.
