**.NET library for processing audio playback as OpenGL textures**

> Version 3 _does not_ require audio loopback drivers for Windows! Loopback is internal!

If you're interested in audio visualization similar to the old WinAmp plugins (Milkdrop!), or more recently, websites like [Shadertoy](https://www.shadertoy.com/) or [VertexShaderArt](https://www.vertexshaderart.com/), then you've come to the right place. Although this is a fully independent library, it is the foundation for the [monkey-hi-hat](https://github.com/MV10/monkey-hi-hat) music visualization application, and the accompanying shaders in my [Volt's Laboratory](https://github.com/MV10/volts-laboratory) repository.

This library does all the hard work of capturing live-playback audio and producing different representations of the sound data as OpenGL textures. On modern Windows 10 64-bit hardware, 4-digit frame rates are not unusual. While Linux isn't officially supported yet, it does work, and it performs well enough that I have used it on a 32-bit Raspberry Pi4B, in some cases attaining 200+ FPS (due to poor/limited GPUs, the Pi will not be supported even after Linux support is officially available). 

Please refer to the repository [wiki](https://github.com/MV10/eyecandy/wiki) for usage, configuration, and other details. The `demo` project is also a good reference, and the library's public API is fully documented. There is even more information in the [monkey-hi-hat](https://github.com/MV10/monkey-hi-hat) wiki that will be of interest to library consumers.

## Demos

The repository's demo project has a lot of useful utilities, and illustrates different ways to use the library. Here is the help output (run the demo program without args to see this):

```

demo [type] [options]

[type]

peaks           Peak audio capture values (use for configuration)

text            Text-based audio visualizations

history         Raw history-texture dumps

wave            Raw PCM wave audio visualization

freq            Frequency magnitude and volume history (multiple shaders)

vert            VertexShaderArt-style integer-array vertex shader (no audio)

frag            Shadertoy-style pixel fragment shader

webaudio        Compares WebAudio pseudo-Decibels to pure FFT Decibels

info            OpenAL information (devices, defaults, extensions, etc.)

                (Windows requires a loopback driver; no WASAPI equivalent)

[options]

F               Full-screen mode

P               Output Process ID

O               Windows: Capture audio with OpenAL-Soft instead of WASAPI
