StemDeck review
A free local separator with six stems, waveform controls, and analysis tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
StemDeck is an open-source audio stem-separation application for musicians, producers, and hobbyists who want to split tracks and work with the results in one place. It processes local audio files or supported URLs on the user's own machine, separating tracks into vocals, drums, bass, guitar, piano, and other. Windows, macOS, and Linux desktop builds sit alongside web and self-hosted options, so it can suit different ways of running audio tools. The Free plan is described as requiring no account or subscription.
The editor and analysis tools make StemDeck more than a basic stem export utility. Its DAW-style waveform editor supports zoom and looping, while the mixer provides per-stem volume, mute, solo, and monitoring controls. Users can choose which stems to extract, generate backing tracks, and export individual stems or mixes in WAV or MP3. BPM, key, scale, loudness, and peak analysis add practical information for arranging and reviewing a track. Library folders, search, and trash help organize projects. Batch processing and API access are also included.
Local processing is the key trade-off: it keeps the workflow centered on the user's own machine, rather than a cloud-first service. URL imports and integrations cover YouTube and SoundCloud, while Docker and Unraid are relevant to self-hosted deployments; the ecosystem is focused rather than broad. StemDeck is a fit for users who value open-source software, local processing, and editor-style controls across desktop or self-hosted setups. Those looking for cloud-based processing or a wider integration ecosystem should consider alternatives.
