Swiss Army knife of audio?We built the whole armoury.

Room correction, active crossovers, parametric EQ, crossfeed, upmixer, asynchronous sample-rate conversion, 8-channel bidirectional I/O, ADAT.

Everything a rack of outboard hardware used to do, on a chip costing less than the cable you plug into it.

Three devices. Endless use cases.

Packing some of the industry's most expensive functionality into a $1 microcontroller.

Let's make everything a clock master. All at once.

Eight channels of digital audio from I2S, SPDIF, ADAT, TDM or PDM into any computer. No drivers.

Measured, not claimed: Where a number is published on this site, it came off a bench or a digital loopback. If a figure is an estimate, it says so.
Driverless by default: Everything here is class compliant. It shows up on macOS, Windows, Linux and iOS with nothing to install and nothing to sign.
Runtime, not reflash: Pins, formats, routing and presets are configuration. Change them from a host tool and the settings persist to flash.
Cheap silicon, serious DSP: All of it runs on a Pico you can buy for the price of a coffee. That is the whole point, and the constraint that makes it fun.

What I have been breaking.

Development chatter, demos, and the place to ask for help when a build will not build.
