Murmur: On-Device AI Music

Every track is one-of-a-kind, made just for you - on your device, in moments. No cloud, no repeats. Requires iPhone 13 Pro or newer.

Murmur is an offline AI music generator for the people who actually need the music video creators, vloggers, podcasters, and game developers. Turn text prompts into 100% royalty-free instrumental loops and soundtracks - generated entirely on your device, with no internet required.

Describe a scene, a vibe, or a setting - "upbeat acoustic for a vlog intro," "warm lo-fi for a podcast transition," or "dark synthwave for a game menu" - and Murmur composes original audio just for you. Nothing is streamed from a server. The AI runs privately on your iPhone's Neural Engine, so your tracks belong entirely to you. Murmur automatically picks the right engine for your device - nothing to configure.

WHY MURMUR • Royalty-Free & Commercial Use: No Content ID claims or copyright strikes. Use your generated tracks anywhere. • 100% On-Device: Works fully offline. Generate B-roll tracks on an airplane or deep in the subway. • No Subscriptions: No expensive cloud servers mean no monthly fees for you. • Original Every Time: No pre-made sample packs or stock music. Every generation is a unique, one-of-a-kind audio file.

YOUR POCKET STUDIO • 170+ Handcrafted Styles: From cinematic strings and ambient drones to acoustic grooves and synthwave. • Export-Ready Audio: Export high-quality WAV files directly to your video editor or save them to your files. • Built-In Editing: Trim, fade, and loop your tracks to fit your project perfectly. • Advanced Engine Controls: Take control of the AI by tweaking parameters to get the exact sound you need.

Whether you are scoring a YouTube video, adding atmosphere to an indie game, or building a library of podcast loops, Murmur is a complete audio studio that lives in your pocket - and runs entirely without the cloud.

REQUIREMENTS Murmur generates music on your device's Neural Engine and needs an iPhone 13 Pro or newer. On older iPhones the model will not load and generation will fail - the app tells you this before the one-time setup download, so nothing is wasted.
