Features
No conversion, ever. A 2-hour set at 320kbps is ~275MB vs ~1.2GB WAV.
Choose your format per source. Full flexibility.
Mic, browser, media playback, desktop audio — if OBS sees it, you can record it.
Each source gets its own file. Stems for days.
Auto-starts and stops with OBS recording. Set it and forget it.
Control all your sources from one tidy panel inside OBS.
Pro Tip
One source, every format.
Add the filter twice to the same audio source and capture MP3 and WAV simultaneously. Archive your set in compressed MP3 while keeping a lossless WAV for editing — both from a single recording pass.
Perfect for DJ laptops
Running Rekordbox, Serato, or Traktor while streaming on the same machine? There's no headroom left for video recording. Audio Stem Exporter captures your mix as a high-quality MP3 with barely any CPU overhead — so you never lose a set.
Can't stream and record video at the same time?
Audio Stem Exporter uses a fraction of the resources of video recording. No encoding, no heavy processing — if your PC or Mac can run OBS, it can run this. Capture your audio stems while you stream, no matter how old your hardware is.
Perfect for content creators
Recording a stream or podcast? Capture each source as its own stem — mic, game audio, music, chat — so you can edit Reels, Shorts, and highlights with full audio control. No more stuck with a flat mix.

Your mix records directly to the file — no conversion step, no extra software.
