Tactus vs Bytebeat

Music you can hold. Tactus turns the music around you into rich, layered touch — bass as a deep swell in your palm, every beat a sharp tap, brightness as texture. Built with and for the deaf and hard-of-hearing community, and for anyone who wants to feel music in a new way. FEEL IT LIVE Point the microphone at the world: concerts, weddings, rehearsals. Live captions transcribe vocals and announcements right under the visuals — entirely on your device. EXPLORE THE TEXTURE Rest the phone on your open palm. Tilt left to feel only the bass bones of a song; tilt right for the rhythm's skeleton. Touch the living matter on screen and slide from its heart (pure bass) to its rim (pure shimmer). KEEP WHAT YOU FELT Every session leaves a tactile print: radial art unique to that song, ready to share — or touch it to feel the whole night again. MADE FOR EVERYONE VoiceOver throughout, magic tap to start and stop, high contrast and calm motion modes, and feel profiles for concerts, home and sleep. No account. No ads. No data collected — nothing ever leaves your phone. Tactus is free.

t*(42&t>>10) That one line is the whole song. Bytebeat turns a formula straight into sound. It evaluates your expression while t counts up from zero, one step at a time, and writes the result out as the waveform. No synthesizer, no audio files, no samples. The formula is the music. ■ Edit while it plays - Rewrite the formula without stopping playback. t keeps running - Change a single character and the song becomes something else - A keypad holding only the characters that appear in bytebeat formulas, so one tap is one character ■ See the waveform - An oscilloscope draws the samples that are actually playing - Traces are aligned to the rising edge, so the wave stays still instead of scrolling - Instruction count and stack depth are shown too ■ 29 famous formulas - Includes the one-liners from the experiments viznut published in 2011 - Save the ones you like to favorites with your own names ■ Three modes - Bytebeat: result & 255 mapped to 0...255, the way the original sounded - Signed: treated as signed 8-bit - Floatbeat: the result used directly as a -1...1 waveform, where sin and cos come alive ■ Change the speed of t - 500 to 48000 Hz. The original bytebeat ran at 8000 Hz - Slower runs lower, faster runs higher ■ Export to WAV - 8-bit, 8000 Hz, mono, which is exactly what bytebeat is - 10 seconds, 30 seconds, 1 minute or 3 minutes ■ What you can write - The variable t, and the constants PI and E - Arithmetic, bitwise operators, shifts, comparison, logic, the ternary operator - sin cos tan asin acos atan abs floor ceil round sqrt exp log sign int pow min max atan2 mod - Everything is computed in Double and rounded to 32-bit integers only for bitwise operations and shifts. This matches JavaScript's ToInt32, so formulas you find on the web play as they are ■ No connection - No account to create - No ads, no tracking - The app never connects to the internet. It works on a plane Many of the presets come from the experiments Ville-Matias Heikkila (viznut) published in 2011.
