Room Impulse Response Generator

RIR-Generator

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.

Credits

• Emanuël Habets (https://github.com/ehabets/RIR-Generator): Provided C++ code with MATLAB bindings
• Marvin (https://github.com/Marvin182/rir-generator): Add python bindings
• Here:
  • Remove shared library and rewrite code, that it only uses cython
  • Let setup.py do everything (i.e. drop makefile call), i.e. support pip
  • Convert examples to tests

Install

You can use pip to install it from github

pip install git+https://github.com/boeddeker/rirgen

or clone it and use pip to install from a local folder

git clone https://github.com/boeddeker/rirgen
cd rirgen
pip install .

rirgen's Issues

Marvin's repository does not exist

It seems that Marvin's repo (https://github.com/Marvin182/rir-generator) which added the Python bindings to the original code, does not exist anymore. Does anyone know what happened?

I suppose its usage in places like this can be replaced with this repo? I am also planning to add it to Lhotse for on-the-fly reverb simulation.
