Wavetable to Image Converter

Static Badge

Description

Serum can turn images into wavetables, but how would wavetables look as images? ~ someone probably

This is a command-line tool that converts WAV files into images. It's useful for generating wavetable images for synths like Serum. It generates them based on samples, not spectrum data.

Maybe i'll expand this cli in the future so you could import images to synths like Harmor too...

Examples

Builting from source

Make sure you have cargo and make installed. Clone this repository and run:

make build

To uninstall, remove wavetable-to-image from ~/.local/bin

rm ~/.local/bin/wavetable-to-image

Usage

wavetable-to-image --input <input_wav_file> --output <output_image_file> -n <skip>
  • --input <input_wav_file>: Path to the input WAV file.
  • --output <output_image_file>: Path to save the output image file.
  • -n <skip>: Number of sample skips per iteration. Adjust this to control the length of the output image.

Example

wavetable-to-image --input test.wav --output test.png -n 32

This command converts test.wav into test.png, skipping 32 samples per iteration.

Batch Conversion

(temporary workaround)

find <input_directory> -type f -name '*.wav' | while read f
do
  wavetable-to-image $f "<output_directory>/$(basename "${f%.wav}.png")" 16
done

Roadmap

  • use wgpu library
  • image to audio conversion
