About this app

PixiVisor is a tool for experimenting with the transmission of video over audio.
It consists of two parts: Transmitter and Receiver.
* Transmitter converts the low-resolution video (stream from camera, static image or GIF animation) to sound in real time, pixel by pixel (progressive scan). So any image or animation can be transferred to the other devices through the sound.
* 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.

Examples of use:
* wireless Lo-Fi video transmission over audio;
* video signal transmission through audio cable; you can then modify that signal by some mixers or audio FX processors;
* VJing;
* sound visualization;
* searching for hidden messages in the ambient noise; EVP (Electronic Voice Phenomenon), ITC (Instrumental Transcommunication);
* save any sound to animated GIF;
* something else...

PixiVisor is also available for iOS, Windows, Linux and macOS.

Control keys:
ESCAPE - exit;
SPACE - play/stop (transmitter);
1,2,3,4,5,6 - slot select (transmitter);
F - hide/show control panel;
[ - previous palette (receiver);
] - next palette (receiver);
I - invert (receiver);
N - normalize (receiver);
1,2 - contrast -/+ (receiver);
3,4 - gamma -/+ (receiver);
5,6 - finetune -/+ (receiver);
7,8 - repeat X -/+ (receiver);
9,0 - repeat Y -/+ (receiver);
LEFT,RIGHT,UP,DOWN - move the image (receiver).

Amazing app. This process of video over an audio signal is called Narrow Bandwidth Television, a system in which an analogue video signal is delivered over an audio signal. I was actually able to record video on audio cassettes and while the video quality isn't as good on cassettes you can still make things out. The only room for improvement is that there should be a mechanism for broadcasting synchronized sound/video, this way users can make Pixivisor movies with it. Thank you for the app.

Interesting concept. To make it more viable it might require specialized microphones and speakers that can go up to extremely high frequencies. Very cool app, works as intended.

I love the concept but I can't get it to work with the camera on any device I own. Is there some setting I'm missing here? Any suggestions would be appreciated. I've tried to use the camera feature on a Galaxy S7, a Nexus 7 2013, and a ZTE axon 7 and still can't get the camera to work. Does this work on any device?
