Stems
Separate songs into vocals, drums, bass, and other WAV parts in a focused app powered by Demucs.
About Stems
Stems is an audio-separation app for DJs, producers, and music learners who need vocals and instrumental parts extracted from a song. Its ST-02 workflow uses Facebook’s open-source Demucs library and keeps separation focused instead of presenting a broad production suite. The product example divides a track into vocals, drums, bass, and other WAV outputs, making the result clear before it enters a remix, practice, or production workflow. A free plan includes three separations per month. The Supporter plan costs $5 per month and adds unlimited monthly separations, access to separation history, and support. Two practical questions determine fit: whether four-part separation serves the intended audio job, and whether the free monthly allowance is enough. Frequent users can remove that allowance with the paid plan, although the recurring subscription becomes part of the workflow cost.

Best use cases
A DJ separates a favorite song before arranging its vocals and instrumental parts into an edit.
A producer exports vocals, drums, bass, and other WAV files before continuing a production session.
A learner isolates individual parts to hear how the arrangement of a song is constructed.
Compare before choosing
The Free plan suits occasional separation work but limits the workflow to three Stems per month.
The Supporter plan removes the monthly separation limit for $5 per month and adds history and support.
The demonstrated four-part output is straightforward when vocals, drums, bass, and other are the required parts.

Pros
- Four named WAV outputs make the separation result easy to route into DJ, production, or learning workflows.
- The Free plan allows three separations per month, providing a limited way to use the core workflow without payment.
- The $5 monthly Supporter plan provides unlimited separations plus history and support for frequent work.
Cons
- The Free plan is capped at three separations per month, which can interrupt higher-volume workflows.
- Unlimited separation requires a recurring $5 monthly subscription rather than remaining within the free allowance.
- The demonstrated output groups audio into four parts, so workflows requiring a different stem structure may need another step.
