# Real-time-SDN
Scattering Delay Networks reverb plugin considering walls absorption.

## Exposed parameters
The plugin exposes the following parameters:
* Source level (dB)
* Source position (3 x 0-1 normalized values)
* Listener position (3 x 0-1 normalized values)
* Listener rotation (3 x 0-360 degrees)
* Output mode (mono, stereo, ACN Ambisonics 1st-5th order)
* Room dimensions (3 x 1-100 meters)
* Wall absorption coefficients (8 x 0-1 absorption coefficients per wall)
* Line-of-sight component (on/off)

## Main classes
* ```Room```: The main class representing the simulation 
* ```Node```: Parent class for all the moving objects in the simulation
* ```Source```: Implements the sound origin 
* ```Receiver```: Models the listener and communicates with the Microphone class
* ```Microphone```: virtual class used as a parent for all the classes implementing the supported output types
* ```ScatteringNode```: Characterizes the first-order reflection’s point of contact with the room walls. Also manages the filtering of the signal
* ```WaveGuide```: Controls the sound propagation in the system. It should be noted that the single instance of this class is mono-directional

## Other tech-specs
Some other info about the plugin:
* Y-up left-handed coordinates system
* Shoebox geometry
* Only one omnidirectional source and one listener
* Multi-channel inputs are treated as mono (input channels are summed up)

## Dependencies
* [JUCE](https://juce.com/)
* [Eigen](https://eigen.tuxfamily.org/)
* [BRT Library](https://github.com/GrupoDiana/BRTLibrary/tree/main) (optional)

## Build notes
The plugin version with HRTF processing requires the [BRT Library](https://github.com/GrupoDiana/BRTLibrary/tree/main) to be included. Additionaly, on Mac or Linux systems, the "mysofa.lib" and "zlibstatic.lib" files (provided by the BRT Library) must also be added as external libraries to link.
