CassetteAI

What CassetteAI does

CassetteAI is a Salt Lake City-based generative audio AI company founded in Q4 2023 by Akhil Tolani under the Delaware-incorporated parent Pixl Technologies, Inc. The company builds real-time diffusion-based audio models covering three modalities: a 300M-parameter adaptive Music Generator (MOD_01) producing 1–4 minute tracks at 44.1 kHz stereo, a Sound Effects Generator (MOD_02) producing 100 ms–30 s loopable clips with per-frame re-roll, and a forthcoming Text-to-Speech Generator (MOD_03) featuring zero-shot voice cloning from 10-second samples. All three modalities are exposed through a single SDK and unified API contract, with the Edge SDK enabling on-device inference at under-50 ms first-sample latency on mobile.

The platform is optimized for interactive and real-time use cases that pre-recorded audio and higher-latency server-side generative models cannot serve. Distribution is anchored on the fal.ai generative-AI marketplace as the hosted inference and primary go-to-market partner, complemented by a public web playground at cassetteai.com/dashboard for no-signup experimentation, an enterprise direct sales channel for volume and on-device licensing, and an email/newsletter channel for developer relations. Engineering, research, SDK, and developer relations teams are distributed across North America and Europe on an async-first basis.

CassetteAI monetizes through usage-based per-second API pricing ($0.02 per output minute for music, $0.01 per SFX generation) with no seat fees, monthly commits, or tier restrictions, plus a freemium Pro tier that extends music generation from 60 seconds to three minutes and unlocks advanced prompt modifiers. Pricing for the TTS model is listed as TBD at launch. The company lists VEED and Rapchat among its users and reports 100,000 requests per month as of 2026, spanning games, creator apps, accessibility tooling, and robotics; revenue is not publicly disclosed.

Core offering

CassetteAI provides real-time generative audio AI models for music composition, sound effects, and text-to-speech, delivered via a unified SDK and hosted API. Customers generate 44.1 kHz stereo audio with sub-50ms latency using pay-per-use API calls through fal.ai, or deploy models on-device through the Edge SDK for privacy-sensitive and low-latency applications.

Product overview

CassetteAI is a real-time generative audio platform offering three core AI-powered products through a unified SDK and API: Music Generator for adaptive music composition, Sound Effects Generator for procedural audio, and Text-to-Speech Generator for voice synthesis. All three modalities share the same API shape and can be accessed via hosted endpoints (fal.ai) or on-device edge SDK. The platform is designed for sub-50ms first-sample latency and 44.1 kHz CD-quality stereo output, targeting developers integrating audio into games, creator apps, AR/VR, and real-time applications.

Products and services

• Music Generator (MOD_01) Adaptive music generation model that creates 1–4 minute tracks from text prompts describing mood, genre, tempo, or key, at 44.1 kHz stereo with deterministic seeds. Available via the hosted fal.ai API at $0.02 per output minute and via the Edge SDK for on-device deployment; targets developers integrating audio into games, creator apps, and real-time applications.
• Sound Effects Generator (MOD_02 / SFX) On-demand text-to-SFX generator producing 100ms to 30-second loop-safe, per-frame re-rollable sound effects from text descriptions. Renders up to 30 seconds of sound in approximately 1 second and is designed for games, video tools, AR/VR, and real-time pipelines. Priced at $0.01 per generation with edge inference support.
• Edge SDK On-device inference SDK that lets CassetteAI's Music and SFX models run inside mobile app bundles with sub-50ms first-sample latency and no server round-trips. Targets privacy-sensitive, offline-capable, or latency-critical application deployments.
• CassetteAI Playground Web-based interactive demo at cassetteai.com/dashboard that lets users generate music and sound effects in the browser without signup or an API key, using preset prompts and customizable duration/seed controls with real-time audio preview and download.
