About MICrODEC

MICrODEC is a work in progress (and probably always will be). It is an open-source platform for Digital Signal Processing (DSP) that is approachable for those familiar with programming Atmel microcontrollers. For those unfamiliar, we hope its a fun excuse to learn.

The hardware itself is of moderately high quality (44.1ksps, 16bit, stereo, -96dB noise, 3Hz - 18kHz frequency response), and has built in features for use with audio effects (wet/dry mix, feedback, mic./instrument/line level inputs). Because of the high data rate, the MICrODEC does not allow for as much processing time as low-end ADC to PWM style microcontroller audio interfaces, but, with 6 seconds of sample time, plenty of useful functions can be executed in the ~400 free clock cycles per sample. And, at a lower cost in comparison to high-end DSP units, it provides a good platform for sound installations where more than a few units may be required.

Features not yet implemented

The current MICrODEC implementation is fun to use, but there are a number of things that would make it even better.
