What our research says

AudioShake

The separation quality post houses and rights holders actually pay for; if you are cleaning dialogue or rebuilding a mix from a stereo master, this is the reference point. A hobbyist remixing one track will find free separators close enough at a fraction of the cost.

Pros

  • Separation set goes well past vocals/instrumental: guitar, dialogue, music detection, multi-speaker isolation
  • Documented REST API at api.audioshake.ai rather than a web uploader only
  • Track record with large rights holders (Disney Music Group, Netflix, Warner Bros., ESPN, Concord) signals licensing comfort
  • Word-level lyric alignment ships alongside the separation models

Cons

  • No public pricing anywhere on the marketing site; the Live tier requires a sales conversation
  • Three separate products (Indie, Live, API) with different entry points and dashboards
  • Credit-based API billing makes cost forecasting harder than a flat per-minute rate
  • Over-specified and over-priced for one-off hobby projects

StemSplit

StemSplit is a straightforward pay-as-you-go vocal and stem separator that also takes YouTube and SoundCloud links directly, saving the step of downloading audio first. The free REST API with webhooks and ready n8n/Zapier guides make it easy to bolt into an existing workflow, though as with other tools in this batch, there is no visible company name behind it.

Pros

  • Accepts direct YouTube and SoundCloud links, not just file uploads
  • Free REST API with webhooks included on all accounts
  • Credits never expire
  • Wide format support up to 500MB, with 4-stem or 6-stem separation options

Cons

  • No subscription option for predictable heavy usage
  • No company name or location published
  • Separation quality for dense mixes is not independently verified here
