Paint2Sound
Paint2Sound is a free software synthesizer and audio converter developed by DocNashSynths. Available format(s): for Windows .
Paint2Sound converts any loaded .jpg or .bmp image, or any picture you care to draw/paint with it, into a soundscape.
Each pixel row of the image represents a frequency band. The application synthesizes sine waves from each pixel row with an instantaneous amplitude determined by the brightness of each pixel in the pixel row, and then sums together all the sine waves.
User control is provided over various parameters such as sample rate, sound duration, the distribution of frequencies across the pixel rows and the overall level in the mix of each sine wave.

Ovalizer
Ovalizer is a free software synthesizer developed by Elcobit. Available format(s): VST for Windows 64b.
Ovalizer emulates digital glitch sounds known from damaged compact discs by automatically remixing layered micro loops synthesized from a live recorded audio source or by importing a WAV file.
The instrument does not require MIDI events to generate polyphone stereo drones. Adjustable pitch and other controls can be randomized with one button click.
Ovalizer is a reminiscence to the famous glitch sounds made popular by such artists as OVAL or AUTECHRE.
