Overview
CassetteAI provides real-time generative audio models for music, sound effects (SFX), and text-to-speech (TTS), designed to run efficiently on edge hardware with sub-50ms latency. The platform utilizes 300M-parameter models to deliver high-fidelity audio at 44.1 kHz stereo, making it suitable for integration into games, creator applications, and other real-time pipelines.
Core Modalities
Adaptive Music Generation
Users can prompt music based on mood, genre, or reference. CassetteAI generates 1–4 minute tracks, complete with drums, bass, harmony, and lead, which can be streamed to an application while a user interacts. It features deterministic seeds and a time-to-first-audio (TTFA) of less than 50 ms.
On-Demand Sound Effects
The SFX engine allows users to describe an event, such as "heavy door slamming in a cathedral," to generate tight, loopable audio clips. These clips are rolled per-frame, range from 100 ms to 12 seconds, and are optimized for edge inference, making them ideal for dynamic environments.
Expressive Text-to-Speech (Upcoming)
The forthcoming TTS model aims to produce natural, expressive speech with zero-shot voice cloning from a 10-second sample. It will support emotion tags inline and is built for streaming-first, real-time pipelines, offering sub-second first phoneme delivery.
The platform offers a single API for all three modalities, simplifying integration. Performance benchmarks show a 30-second music sample renders in under 2 seconds, and a full 3-minute track in under 10 seconds, while SFX are ready in approximately 1 second. A live playground is available for testing without requiring a signup.
