About

Wormhole

Features
Read full description

Wormhole turns any sound you have into music you made. Drop in a clip โ€” a video from your camera roll, a voice memo, a file, or something you hum into the mic. Wormhole listens to it, finds the tempo and the key on its own, and chops it into slices you can play. From there you are one tap away from a beat. FIVE INSTRUMENTS, ONE SCREEN Drums, 808, keys, your chopped clip, and a lead โ€” all on one page. Tap a row to open its notes and draw them straight in. There is no edit mode to learn and no menu tree to climb. If you can tap, you can write a pattern. EVERY NOTE IS IN KEY Wormhole knows what key your project is in and keeps every instrument inside it. You can't place a wrong note. Change the key later and your melodies move with it โ€” the app remembers the scale degree, not the absolute pitch. THE WORMHOLE Send any sound into the Wormhole and it comes back out in your key. Freeze a single grain into a pad. Smear a vocal into a choir. Stutter a snare into a fill that was never played. It is a scale-locked granular bus, and it is the reason the app is called what it is called. CHOP IT YOUR WAY Slice on transients, slice on the grid, or cut it by hand โ€” tap the waveform to add a cut, drag a dot to move one. Pick a part of a long clip and chop only that. Every slice gets its own pitch, filter, and length. STUCK? PRESS FLIP One button writes a whole beat โ€” drums, bass, chords, melody, all in your key, all editable. Press it until something grabs you, then make it yours. LOOPS BECOME A SONG Build up to four versions of every instrument, then place them on a timeline. Drag a block's edge to repeat it. That is the entire arrangement view. POST IT Export a 1080x1920 vertical video with a reactive visual, ready to go straight to your feed. Or take M4A for other apps and 24-bit WAV for your DAW. BUILT PROPERLY Real-time audio engine written from scratch. No login, no account, no cloud, no tracking โ€” your projects live on your phone. Works fully offline. Something you already have is a beat. It just needs chopping. https://wormhole.aimoxyz.xyz/terms
