StemSplit review
A low-cost, credit-based option for stem separation and automated audio workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
StemSplit is a web-based AI audio tool for removing vocals, making instrumentals, and splitting songs into stems. It is aimed at DJs, producers, karaoke creators, singers, educators, content creators, and developers who want either an online workflow or programmatic access. Users can upload audio or submit source URLs, select vocal or instrumental output, or request four- or six-stem separation. Outputs are available in MP3, WAV, and FLAC.
Its pricing is credit-based and one-time rather than subscription-based. Starter costs $2 for 10 minutes; Standard is $5 for 30 minutes; Pro is $12 for 100 minutes; and Studio is $30 for 300 minutes. Each plan includes MP3, WAV, and FLAC support, vocal and instrumental output, credits that never expire, and full API access. New accounts receive 5 free minutes as a limited trial, not a time-unlimited free plan. The small entry purchase and non-expiring credits suit occasional jobs, while buyers with recurring volume can compare the larger packs by processing minutes.
The API and automation options are a notable fit for workflow builders: StemSplit supports REST API access with bearer-key authentication, webhooks for completed jobs, batch processing, and integrations including GitHub Actions, n8n, Zapier, Make, Pipedream, Microsoft Power Automate, and Discord. It also accepts source URLs, including YouTube and SoundCloud processing jobs, and offers voice cleaning and denoising. Choose StemSplit when low-cost separation, API access, or automation matters; look elsewhere if a desktop app or an ongoing free plan is essential.
