Music and sound for your game
Brief it the way you'd brief a composer: the place, the pace, the instruments. A village theme comes back as two versions you can loop, with the drums, bass, guitar and keys on separate tracks for the engine to mix.

What you can make today, and what's next
Live now works today. Launching is rolling out now.
Themes for each area
Live nowDescribe the village, the dungeon or the boss fight. Set the tempo and key or leave them on auto, and pick from two versions up to two minutes long.
Loops that don't click
Live nowTurn on loop and the track is cut to whole bars, so it repeats under a level with no gap at the seam.
Stems for adaptive music
Live nowDrums, bass, guitar, keys and other come as separate lossless files that add up to the mix. Bring the drums in when the fight starts.
Sound effects
Live nowFootsteps, sword hits, doors, a crowd in the market. Describe the sound and get a WAV up to 30 seconds long.
Fix one part
Live nowDon't like the bass? Redo it and the other four parts stay as they were. Or open the song in Studio and change it while it plays.
Music from your concept art

Where it fits in your pipeline
- From the editor or a build stepCall the HTTP API from Unity or Godot; the docs have examples in C# and GDScript. Keep the key on your machine or server and ship the audio files.
- From Claude CodeAdd the MCP server and ask for “a looping theme for the forest level, with the stems”. Any MCP client works.
- By handUse the generator on the web, or Studio when you want to rework a track part by part.
- File formatsMP3, 16-bit WAV at 48 kHz, and the five stems as FLAC, from 2 seconds to 2 minutes long. The links don't expire.
Pricing and rights
- 5 songs a month are free on the web, in Studio and through the MCP server.
- Through the API, each song is $0.05 (5 credits) from a pack: $3 makes 60, packs don't expire, and the larger ones are up to 30% cheaper. No subscription.
- Everything you make is cleared for commercial use, including in games you sell, on every plan.
