OBS Track Extractor
Pull the mic, desktop, game and music tracks out of an OBS recording as separate files. Lossless, in seconds.
Record with several audio tracks in OBS and every track is locked inside one file: mic, desktop, game, music, voice chat. OBS Track Extractor lists those tracks and writes the ones you choose as separate files, losslessly, in seconds.
It lists every audio track with the names you gave them in OBS, plus codec, channels and sample rate. It exports an exact copy of the recorded audio (no re-encoding), or WAV, or FLAC, and names the files the way you want.
Your recording is only ever read. It is never rewritten, and an existing file is never overwritten. Runs completely offline: no account, no analytics, nothing uploaded.
A command-line tool for Windows 10 and 11 with a built-in self test. It requires FFmpeg on your PATH (free; one winget command).
Privacy: the program runs entirely on your PC. No account, no network requests, no data collected. Sold through itch.io, which handles the payment.
