## What is PixiVisor?

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...

Control keys:
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).

### 5/5 — feature request: import/export audio

*2024-06-29*

great app! lots of fun to play with when you have two devices. 

i wish it were possible to export the transmission audio as a .wav file, and import an audio file to the receiver. any chance of these features being added?

audiobus support would be amazing, too!

### 5/5 — Imaginative, great for design inspiration

*2024-01-21*

Very clever idea. Fun to play with the noise. I wish I could hook up an external monitor for a two screen solution. That is, have the controls on pad and the video only on the second monitor

### 3/5 — Very cool

*2022-12-26, version 1.3d*

Please implement files app access and photo album access.

### 5/5 — A Favorite

*2021-12-12*

A favorite app from a favorite dev.  Would love it if there was a more full featured video synth that looked like this and would output scaled up video file.  Perhaps have it work as a music visualizer, maybe with blendable inputs to modulate images.

### 5/5 — Amazing

*2020-03-30*

I’ve only used it for 5 minutes so far and it’s already my favorite app. Awesome. Thank you.

### 5/5 — Vid Synth!

*2019-09-25*

Feed an external synth in through an audio interface or chain together stuff in AUM (effects, etc). Only good things happens. Easily the best vid synth on iOS.

### 1/5 — Does Not Work

*2019-02-17*

I installed it on two iPhones, and my computer. None of the apps work. No matter how loud/quiet, near/far, no matter the settings on either. All either produce are static and rolling pictures, even using the included animations and static images.

### 5/5 — Превосходно

*2018-07-15*

Это просто нечто, Спасибо Вам за это чудо!

### 5/5 — やり方次第で

*2018-02-22*

映像を音に変換し伝送するのもいいし、ユーザー自身の音を映像に変換することも可能なので、新しい音楽表現方法が生まれる可能性があると思う。見て面白い映像になるような音を出すためのコツがいくつかあるみたいなので、色々と実験しているところだ。最も気に入っているポイントはオーディオというアナログ信号で映像をいじれるところ。

### 5/5 — ❤️

*2017-07-18, version 1.1*

Love this!

## Frequently asked questions about PixiVisor

### What does PixiVisor do?

PixiVisor allows you to transmit low-resolution video signals through audio. The transmitter converts video sources like camera streams, static images, or GIFs into sound, while the receiver converts that sound back into a video signal. You can then customize the video's appearance and save it as an animated GIF.

### How can I use PixiVisor?

You can use PixiVisor for wireless Lo-Fi video transmission over audio, sending video signals through audio cables, VJing, sound visualization, and even for exploring phenomena like EVP and ITC. It can also be used to save any sound into an animated GIF.

### Is PixiVisor free to use?

Yes, PixiVisor is a free application. There are no in-app purchases or advertisements mentioned in its description, indicating it is entirely free for users.

### What kind of video quality can I expect?

The app is designed for low-resolution video transmission. The real-time conversion is done pixel by pixel, resulting in a Lo-Fi aesthetic. This is intentional for its experimental nature and unique transmission method.

### Can I record the received video?

Yes, the receiver component of PixiVisor allows you to record the converted sound back into a video. You can then save this recorded video as an animated GIF file, with options to adjust color palettes and other visual parameters.
