PixiVisor is a multimedia tool designed for experimenting with the transmission of video over audio. Developed by Alexander Zolotov, this iPhone application offers a unique way to convert low-resolution video into sound in real-time. The program consists of two parts: Transmitter and Receiver.

The Transmitter component converts low-resolution video, whether it's a live stream from the camera, a static image, or a GIF animation, into sound pixel by pixel. This progressive scan technique allows any image or animation to be transferred to other devices through sound.

On the other hand, the Receiver component converts the sound from the microphone or Line-in input back into video. Users have the ability to set the color palette for the video output and even record it as an animated GIF file.

PixiVisor offers a wide range of applications, including wireless Lo-Fi video transmission over audio, video signal transmission through an audio cable for modification using mixers or audio FX processors, VJing, sound visualization, and even searching for hidden messages in ambient noise.

The program provides intuitive control keys for easy navigation and manipulation. Users can play/stop the transmission, select different slots for transmitting, hide/show the control panel, adjust various settings such as palette, contrast, gamma, and image movement.

Overall, PixiVisor is a versatile tool that opens up creative possibilities for artists, musicians, and enthusiasts who want to explore video transmission through audio. For more information, test broadcasts, and videos, visit the developer's website.
