Murmur: On-Device AI Music

About this app

<p>Murmur makes original, royalty-free instrumental music on your iPhone, for your videos, games, podcasts and focus sessions. No cloud, no subscription, no waiting on a server.</p>
<p>MEET ORPHEUS<br />
Murmur's new engine, powered by Stability AI, composes a full track in seconds and goes up to 6 minutes long. Describe a scene, a mood or the instruments you want, or start from one of 170+ curated styles, and Orpheus writes it for you, right on your phone. Its model was trained on licensed and Creative Commons audio.</p>
<p>MADE FOR CREATORS<br />
• Background music for YouTube, Reels and vlogs<br />
• Loops and soundtracks for indie games<br />
• Beds for podcasts, ads and presentations<br />
• Lo-fi, ambient, cinematic, electronic, jazz, acoustic and many more</p>
<p>PRIVATE AND OFFLINE<br />
Every track is generated on your iPhone. Your prompts and music never leave your phone, and after a one-time setup download Murmur works without an internet connection.</p>
<p>GO LIVE<br />
Live mode streams a continuous instrumental set in real time. Steer it like a DJ with the knob deck: fade beat, bass, keys, pads, guitar, strings and more in and out while it plays, then save the jam to your Library.</p>
<p>YOUR LIBRARY<br />
Save tracks, rename them, trim, fade and loop them in the editor, and export WAV files ready for your edit.</p>
<p>FREE AND PRO<br />
Murmur is free to download, with free tracks every day. Murmur Pro is a one-time purchase, not a subscription. It unlocks unlimited tracks up to 6 minutes each, all 170+ styles, custom prompts, Live mode without limits and WAV export.</p>
<p>ROYALTY-FREE<br />
Music you make with Murmur is yours to use, with no licensing fees for us or the model providers. As with any AI-generated audio, automated content-matching systems can occasionally flag a false match; that is disputable with the platform.</p>
<p>REQUIREMENTS<br />
The Orpheus engine needs iOS 18 or later and a one-time download of about 2.1 GB (Wi-Fi recommended). It runs best on iPhone 13 Pro and newer; other iPhones can try it as a beta or use the Classic engine.</p>
