Description

A reasonably decent sounding audio device, which allows users to build several audio experiments, but is customisable enough that you don't need to build the whole thing.

Has a DAC, Digipot (controlled by an ATtiny1614), a CMoy based headphone amplifier with a configurable HPF and gain, and a second stage amplifier with a configurable Sallen-Key LPF for filtering out higher frequencies and customising every aspect of the users taste and frequency response.

Oh, and blinky lights VU meter (powered by another ATtiny1614@20Mhz), because you want to see your work, working.

Details

All details can be found on the github page, along with firmware and sourcecode.
