Questions
How big is the Audio Visualiser PCB?
It measures 101 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio Visualiser use?
13 parts. 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 Visualiser KiCad files?
From the The-Wolfson/Audio-Visualiser repository on GitHub, at the commit this page was made from: the board is Audio Visualiser.kicad_pcb and its schematic Audio Visualiser.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio Visualiser design in my own project?
Its repository states no licence, so its author keeps all rights: ask The-Wolfson before reusing the design.
