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
