ByteBeat

Turn one line of math into a full techno track. New in 1.6: a proper code editor with highlighting, located errors, and one-tap operators.

Turn tiny formulas into surprising sound.

ByteBeat is a creative coding playground where one line of math becomes music — techno, chiptune, glitches, drones, and textures you won't find in a normal music app. Write a formula, press play, hear it instantly.

Not a coder? Load a preset and change one number. That's the whole learning curve.

START FROM REAL TRACKS 22 built-in presets: classic one-liners like ((t>>10)&42)*t, plus full arrangements in driving, melodic, dark and industrial techno, deep and progressive house, trance, synthwave, drum and bass, cinematic and lo-fi electronic, and ambient. Every one opens in the editor, so you can read how it works and rewrite it.

A REAL CODE EDITOR Syntax highlighting, line numbers, undo and redo, and a one-tap row for the operators bytebeat actually uses. When something breaks, the error points at the exact line and column instead of just going silent.

LEARN AS YOU GO Built-in training explains what t, *, >> and & really do, with sample formulas you can load, play, and change on the spot.

SEE YOUR SOUND An audio-reactive visualizer runs behind your code, with a full-screen mode and switchable skins and scenes.

EXPORT AND SHARE Render WAV up to 60 seconds, export video sized for TikTok or Instagram, or share a link that opens your exact formula on someone else's phone.

UNDER THE HOOD • Classic and JS-big evaluation modes • Bytebeat, signed bytebeat, and floatbeat output • 44.1 kHz or 8 kHz, adjustable buffer size • Save your own presets to a personal library

No setup. No accounts. No internet required. Just code, sound, and experimentation.
