CassetteAI

CassetteAI is a generative audio platform that produces music, sound effects and, soon, speech from text prompts through a single API. Its models are small, at roughly 300 million parameters, and are designed for fast response so audio can be generated inside games, creator apps and real time pipelines rather than as an offline batch job. The music generator takes a mood, genre or reference and returns tracks of one to four minutes at 44.1 kHz stereo, delivered as WAV. A 30 second preview sample renders in under two seconds and a full three minute track in under ten, according to the vendor's published timelines. The sound effects generator turns descriptions such as a door slamming in a cathedral into clips from 100 milliseconds to 12 seconds long, with loop safe output and the option to re roll per frame. A text to speech module with zero shot voice cloning from a ten second sample and inline emotion tags is marked as launching soon. The site includes a playground that works without signup. It suits game developers, app builders and creators who need audio generated on demand inside a product. CassetteAI describes itself as a small research team based in Salt Lake City, founded in 2023. Pricing is pay per use with no monthly commitment and no developer seats: $0.02 per output minute of music and $0.01 per sound effect generation.
