Cassette AI

Product details from official sources

CassetteAI is a real-time generative audio API for games, creator apps, and real-time pipelines: one SDK with three engines — adaptive Music (1–4 minute tracks at 44.1 kHz stereo), on-demand SFX (up to 30 seconds rendered in about a second), and TTS with zero-shot voice clone (listed as launching soon). The models are 300M-parameter and edge-capable with sub-50ms latency; a 30-second sample renders in under 2 seconds and a full 3-minute track in under 10. Pricing is pay-per-use with no tiers or seats: $0.02 per output minute for music, $0.01 per SFX generation.
