Noise Nugget is a compact digital synthesizer based on an 180MHz Cortex-M4 and quality audio DAC with headphone amplifier.

My goal with this project is to create a little "Swiss Army knife" of audio synthesis. Packing the maximum features on the smallest and cheapest board.

With all its connectivity (USB, 2 x audio out, 1 x audio in, I2C, UART, GPIOs) it can be used for many different tasks:

• Digital synthesizer, with a MIDI interface or some other means of control
• Audio effects, for a guitar pedal or synthesizer (delay, reverb, distortion)
• Audio FX trigger board, playing pre-recorded sounds
• Audio playback, recording sounds from the input and then playing it back at the push of a button
• USB sound interface

So far I implemented one audio effect, a MIDI over USB synth and sampler. Noise Nugget is a compact digital synthesizer based on an 180MHz Cortex-M4 and quality audio DAC with headphone amplifier.
