Our verdict on CassetteAI
CassetteAI is an AI audio-generation platform for creating music and sound effects from text prompts. Its web studio supports duration controls, audio references, video uploads, track extension, stem separation, MIDI export, and private-mode controls. The product also offers music and sound-effects APIs, making it suited to developers building games, creator applications, and real-time audio pipelines across web, mobile, and self-hosted environments.
Pricing is organized around studio access and API usage. The Hobby plan references free studio access through the account interface. Pro and Pro annual include 500 creations per month, three-minute creations, MIDI export, stem separation, and a commercial use license. The Music API costs $0.02 per output minute with monthly billing, supports 10–180 seconds per call, and provides 44.1 kHz stereo output with deterministic seeds. The Sound Effects API costs $0.01 per generation and supports outputs up to 30 seconds, loop-safe results, and per-frame rerolls.
CassetteAI’s main strength is breadth: one product covers prompt-based music, sound effects, reference media, downloadable production elements, and programmable generation. JavaScript, Python, cURL, and fal.ai support give developers several integration paths, while web, iOS, and Android access extends the studio beyond a single interface. The trade-off is that it may not suit projects requiring tracks longer than three minutes through the Pro studio or sound-effect generations longer than 30 seconds through the API. Choose CassetteAI for integrated music and sound-effects workflows with API access; consider a narrower alternative when long-form audio is the primary requirement.
