The honest brief
CassetteAI
Optimized for sub-second latency—a 30s clip in about two seconds at 44.1kHz—so it fits real-time and high-volume API use, unlike batch-only generators.
- Sub-second generation latency
- Music, SFX, and speech in one API
- Pay-per-use, no subscription lock-in
- 44.1kHz stereo output
- Newer, smaller catalog than Suno/Udio
- API-first; limited standalone editor
- Commercial-rights terms not clearly stated
Stable Audio
Trained on AudioSparx-licensed music, pitched as commercially clean — unlike rivals trained on scraped audio now facing lawsuits.
- Music + sound-effects generation
- Trained on licensed data
- Web studio plus generation API
- Backed by Stability AI
- Vocals weaker than song-first rivals
- Free tier limits length/generations
- Commercial use needs subscription
