ByteBeat vs Callback Freeverb

Draw a shape. Hear it as music. Or write one line of math and press play. ByteBeat is a creative coding playground where sound comes from code — techno, chiptune, glitches, drones, and textures you won't find in a normal music app. Not a coder? Draw something. That's the whole learning curve. DRAW IT, HEAR IT, SEE THE CODE New: Sound Canvas. Draw a line and it becomes a loop — left to right is time, up is higher. Add layers for harmony, bass and drums, or tap Make It a Track and let the app build an arrangement around your shape. Pick a mood instead of a scale if you don't know what a scale is. Then open the code. Your drawing is a real, readable program you can edit — change the tempo, the key or the notes, and the canvas follows. 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 • Six sample rates from 8 kHz to 44.1 kHz, adjustable buffer size • Save your own formulas and canvases to a personal library No setup. No accounts. No internet required. Just code, sound, and experimentation.

A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.
