Cassette AI

What if every product could have its own dynamic soundtrack, generated on demand?

RecommendedCassetteAI offers a powerful, developer-centric API for real-time generative audio, positioning itself as a crucial sound layer for modern software with a strong focus on speed and edge deployment.

CassetteAI provides an API for real-time audio ML, enabling the generation of music, sound effects, and text-to-speech. It focuses on low-latency generation, with 30-second music samples in under 2 seconds and full 3-minute tracks in under 10 seconds, all at 44.1 kHz stereo.

FAQ

How fast is CassetteAI's audio generation?

For music, a 30-second sample returns in under 2 seconds and a full 3-minute track in under 10 seconds. For SFX, up to 30 seconds of sound renders in roughly 1 second of processing time. All output is 44.1 kHz stereo.

Can I use CassetteAI's generated audio for commercial projects?

Yes, creations made on the Studio Pro plan can be used for commercial projects. For API usage, users assume responsibility for determining the appropriateness of using or redistributing generated content and all liabilities for any infringement.

What are the pricing models for CassetteAI?

CassetteAI offers a pay-per-use API model ($0.02/output minute for music, $0.01/SFX generation) and a freemium Studio plan. The Studio Hobby plan is free with 500 creations/month, while the Pro plan costs $3.33/month (billed yearly) with more features and higher limits.

Is Text-to-Speech (TTS) available?

The TTS generator is listed as 'soon' and is not yet launched. It is planned to offer ultra-realistic voices with streaming output and sub-second first phoneme.

What kind of audio can CassetteAI generate?

CassetteAI can generate adaptive music based on mood, genre, or reference; sound effects based on descriptions; and will soon offer natural, expressive speech with zero-shot cloning and emotion tags.
