Description
The Spotykach reads 48 kHz stereo 32-bit float WAV files from its SD card, with six tapes of six slots each and only the first 42 seconds of a slot used. WAV Builder converts and trims audio to that format, lets you browse and collect sample packs, build projects of tapes and slots with notes, write a ready card, import recordings made on the Spotykach, edit the device's config.txt (MIDI channels, preloading, transport, slice mode) and mangle random snippets into one file. It runs in the browser and works best in desktop Chrome or Edge.
Install notes
Nothing to install. Open the web app, then write the result to the Spotykach's SD card.
