In this repository we combine two methods of IR generators.
The image method, proposed by Allen and Berkley in 1979 [1], is probably one of the most frequently used methods in the acoustic signal processing community to create synthetic room impulse responses. A mex-function, which can be used in MATLAB, was developed to generate multi-channel room impulse responses using the image method. This function enables the user to control the reflection order, room dimension, and microphone directivity.
This repository includes a tutorial, MATLAB examples, and the source code of the mex-function. A similar interface is available as a Python module and a C++ shared library.
