Questions

What parts does the Audio processor use?

58 parts, built around the LMV321. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Audio processor KiCad files?

From the AMOY-05/Audio-Processor-PCB-Design repository on GitHub, at the commit this page was made from: the board is audio_processor.kicad_pcb and its schematic audio_processor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Audio processor design in my own project?

Its repository states no licence, so its author keeps all rights: ask AMOY-05 before reusing the design.
