PixiVisor is a revolutionary tool for audio-visual experiments.
Simple and fun, cross-platform application with unlimited potential for creativity!
It consists of two parts: Transmitter and Receiver.
Transmitter converts the video (static 64x64 image or 10FPS animation)
to sound, pixel by pixel (progressive scan). This lets you listen to the
sound of your image.
But the main function of the Transmitter is to transmit the signal to
the receiving devices.
Receiver converts the sound (from microphone or Line-in input) back to
video. You can set the color palette for this video, and record it to
animated GIF file.
