Pick a clip, get music made for it. Analyzed and composed right on your iPhone.
Choose a photo or video and Murmur suggests music that fits it: three ideas for the scene, matching presets, Moments, and Story Worlds. Pick one, set a feeling, and Orpheus composes a soundtrack exactly as long as your video. Try again or try another idea without losing a take, then save the video with its new music, share it, or post it to Instagram.
Your photos and videos never leave your iPhone. Scene ideas need Apple Intelligence (iPhone 15 Pro or newer, iOS 27). On other iPhones, Score works with presets, Moments, Story Worlds, or your own words.

Frequently asked questions
Royalty-free AI music, on-device generation, and commercial use — answered.
Orpheus is Murmur's newest music engine, powered by Stability AI. It composes a full 30-second track in seconds on recent iPhones and goes up to about 6 minutes per track — right on your iPhone, with no internet needed after a one-time download. Its model was trained on licensed and Creative Commons audio. Murmur's original Magenta RT engines are still there: they power Live mode and stay selectable as the Classic engine in Settings. Orpheus needs iOS 18 or later.
Murmur is free to download, and you get free tracks every day: with the Orpheus engine, three tracks a day up to 30 seconds, plus one free long track. Every track is royalty-free, free tier or Pro. Murmur Pro is a one-time purchase (a lifetime unlock, not a subscription) that opens the full studio: unlimited tracks up to 6 minutes each, all 170+ presets, custom scene prompts, Live mode, WAV export, and advanced controls. No monthly fees, ever — check the current price on the App Store.
Yes, with Score mode, new in Murmur 2.2. Pick a photo or video and Murmur composes a soundtrack for it on your iPhone, exactly as long as your video. On iPhones with Apple Intelligence (iPhone 15 Pro or newer, iOS 27), Apple's on-device model looks at the scene and suggests three musical ideas that fit it. On other iPhones, Score still works: start from presets, Moments, Story Worlds, or your own words. You can keep or mix in the original sound, then save the finished video to Photos, share it, or post it to Instagram. Free scores cover photos and videos up to 30 seconds and carry a small "Made with Murmur" mark; Pro scores full-length videos without it. Your photos and videos never leave your iPhone. Score uses the Orpheus engine (iOS 18 or later).
Yes. Live mode streams a continuous instrumental set, composed second-by-second on your iPhone by a dedicated fast on-device engine. Pick a starting instrument, tap Go Live, and the music starts within seconds — then steer it like a DJ with the knob deck, fading layers like beat, bass, keys, pads, guitar, synth, strings, brass, and arps in and out while it plays. You can save the jam to your Library when you're done.
Live sessions are limited to a few minutes at a time. Real-time generation is intensive — as your iPhone warms up, thermals can slow the engine to protect the chip. Murmur is built for jamming and capturing a take, not hour-long sets. Save your session to the Library before it ends. As future iPhones get faster and more efficient, Live mode will only get better.
No. Murmur is a pure instrumental music generator. It is designed specifically to create high-quality background soundscapes, lo-fi beats, and cinematic loops that fit seamlessly under video production and indie games without vocal clutter.
Yes. Every track you generate with Murmur, free tier or Pro, is royalty-free and can be used commercially — nothing to license, and neither Murmur nor its model providers claim rights over what you generate. As with any AI-generated audio, an automated system like YouTube's Content ID could in rare cases flag a false match; that's a third-party detection issue, not a rights issue, and is disputable.
Yes. Murmur generates AI music entirely on your iPhone — with the Orpheus engine (powered by Stability AI) and Google's Magenta RT models, accelerated by Apple silicon. Your prompts and generated audio are processed locally — not sent to a cloud server for rendering.
Murmur is built for privacy. The core music generation flow runs on-device, so your prompts and generated instrumentals stay on your phone. We don't collect your audio, and there's no cloud rendering step.
Murmur is designed for private, on-device AI music generation on iPhone. Once the AI models are downloaded, you can compose instrumental tracks from presets or your own scene prompts without relying on cloud generation.
You pick a preset or describe a scene in your own words. The Orpheus engine (powered by Stability AI) turns that text into an original instrumental track with a diffusion model running on your iPhone's GPU — a 30-second track takes seconds. Live mode uses Google's Magenta RT on the Apple Neural Engine to compose music in real time.
You need a connection the first time to download the AI models. After that, generation runs locally on your phone. Murmur doesn't require cloud rendering for each new piece of music you create.
Most AI music tools render in the cloud, which means expensive GPU servers and costly monthly subscriptions. Murmur generates music on your iPhone instead — no cloud rendering, no expensive data servers to run, and no pricey subscription just to cover infrastructure. You get private, local generation with instrumental output, 170+ curated presets, and custom scene prompts powered by on-device AI.
