Wow & Flutter is a pitch modulation source designed to emulate the nostalgic warbles of a aged tape deck.
Output is selectable between triangle or random sample and hold with slew. A jumper on the back of the module sets three different output levels

Questions
How big is the Wow and flutter PCB?
It measures 127 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wow and flutter use?
72 parts, built around the J113. 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 Wow and flutter KiCad files?
From the mprosk/wow_and_flutter repository on GitHub, at the commit this page was made from: the board is wow_and_flutter/wow_and_flutter.kicad_pcb and its schematic wow_and_flutter/wow_and_flutter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wow and flutter design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
