Mozzi — when Arduino sounds like never before

Remember the standard Arduino beep that sounds like a microwave? With the Mozzi library, those days will be a thing of the past. This project turns your board into a real synthesizer, capable of creating complex sound textures — from smooth sweeps to atmospheric soundscapes.

Why Mozzi is a breakthrough

Most developers have encountered the limitations of standard Arduino sound generation capabilities. Mozzi solves three key problems:

Rich sound — from simple tones to complex synthesized sounds
Ease of use — working with familiar synthesizer building blocks (oscillators, filters, envelopes)
Minimal requirements — no additional boards or complex circuits needed

Key features

Wide board support

Mozzi works with dozens of popular boards:

Classic Arduino boards (Uno, Nano)
Modern solutions (ESP32, Raspberry Pi Pico)
Specialized boards (Teensy, STM32)

Flexible audio output

Choose the optimal mode for your project:

Built-in DAC (where available)
PWM output
External DAC support via I2S/SPI
Even Bluetooth output!

Full-featured synthesis

At your disposal:

Various oscillator types
Filters (resonant, state-variable)
Envelopes and LFO
Ready-made wavetables

Getting started

Installation is a breeze — through the Arduino library manager. A basic sketch looks concise:

#include <Mozzi.h>

void setup() {
  startMozzi();
}

void updateControl(){
  // Ваш управляющий код
}

AudioOutput_t updateAudio(){
  return MonoOutput::from16Bit(/* ваш звук */);
}

void loop() {
  audioHook();
}

Practical applications

Interactive installations — add sound to sensor data
DIY synthesizers — create your own unique instrument
Sound design — generate effects for games or films
Educational projects — visual demonstration of sound synthesis basics

Limitations

Uses hardware timers (may conflict with other libraries)
Requires careful code without blocking operations
On low-power boards (ATmega328) there are limitations on sound complexity

Mozzi is the best way to add quality sound to Arduino projects without extra costs. The project is actively developing, has good documentation and community. If you work with sound on microcontrollers — definitely try it!

Perfect for:

Electronic musical instrument creators
Interactive installation developers
Sound design enthusiasts
Anyone who's tired of the standard Arduino "beep"
