Mirelo

Mirelo is a Berlin-based AI research lab building state-of-the-art audio foundation models for visual media. Its flagship Mirelo SFX model generates production-ready, perfectly synced sound effects directly from video (or from text prompts) with no background-music noise, plus iterative editing, audio inpainting, sound extension, and a multi-instrument Audio-to-MIDI model. Mirelo ships a self-serve REST API (https://api.mirelo.ai/v2/), the Mirelo Studio web app, official Node.js and Python SDKs, and editor plugins for Adobe Premiere Pro, DaVinci Resolve, Reaper, and Roblox Studio. The models are also distributed on fal.ai, Replicate, and Runware. Founded by musicians-turned-AI researchers from Amazon, Google Brain, Max Planck and ETH Zurich, Mirelo raised a $41M seed round co-led by Index Ventures and Andreessen Horowitz in December 2025.

Mirelo publishes 1 API on the APIs.io network. Tagged areas include Company, Ai Ml, Audio, Sound Effects, and Generative AI.

Mirelo’s developer surface includes documentation, API reference, engineering blog, pricing, support, signup flow, authentication, and 15 more developer resources.
