Sketch Synth

Change contrast

Open image file

Dropdown menu for audio output

Short description

This is an experimental test app. It works like the UPIC of Iannis Xenakis or synthesizes images as sound. In particular, this application uses hand-drawn sketches to convert music and synthesizers.

  • First, load a hand-drawn image (jpg or png, key : 'o')
  • Moving and set up a position of the red wavetable zone and the green play zone
  • Change the contrast parameters of the selected area
  • Playing and stopping is by spacebar
  • Optional parameters are speed, frequency, overlap
  • Dropdown menu for audio out devices

A hand-drawn sketch image should be on the white background. If the background of the image is darker than a sketch, the 'Invert colors' option creates a better play and wavetable area.

There will be more features and updates.
