Plinky wavetable generator

This is a wavetable header generator for Plinky.

It expects files from c0.wav to c14.wav in the same folder.

Wavs must be in this format:

a single cycle waveform, of at least 512 samples (this tool resamples it to 512)
16 bits
mono

The generator downsamples the waves for Plinky (32kHz) and generates various octaves pre-filtered.

Building

clang++ -O2 wavetable.cpp -o wavetable

Running

./wavetable

It should generate a wavetable.h which you can use in the main Plinky project- just copy it to Core/Src/wavetable.h and recompile the Plinky firmware.

wavetab.uf2

The generator will now also generate a wavetab.uf2 which you can just toss over to plinky! yay!

Prebuilt binaries

There are prebuilt binaries for MacOS and Windows in the repo (PlinkyWavetable.exe for Windows and wavetable for MacOS)
