Hear your
equations.
Mathestra is a graphing calculator for sound. Write , where x is time in seconds and y is where the speaker cone sits, then press play.
Every line is a sound.
Nothing is invented on top of the maths. Each line is a pressure wave, and lines add together exactly the way sounds add up in air.
Start from a piece.
Every example is plain equations you can open, read and change. Press play on any of them to listen first.
What you get
Typeset as you type
Equations look like they do in a textbook, with italic variables and raised exponents, while you edit plain text.
A keypad for maths
Roots, powers, trig, lists and piecewise functions, one tap away on desktop and phone.
Sliders you can play
Any number can become a slider. Drag it while the sound runs and hear the change immediately.
Saved and shared
Keep your pieces in your account, or send a link that plays exactly what you made. No install.
Your first song is one line away.
