MCROOMSIM

By Andrew Wabnitz & Nicolas Epain

Overview

MCRoomSim is a multichannel shoebox room acoustics simulator used for generating reverberant room impulse responses of any user defined rectangular room.

Please refer to the accompanying paper. Paper on MCRoomSim

Uses

Realistic in-room microphone array simulation for the evaluation of beamforming or spatialisation techniques

Playback of virtual echoic sound fields in 3D

Spherical harmonic expansion of echoic sound fields

Evaluation of directive sources in an echoic room

Key Features

Extension to MATLAB (mex) written in C

Fully configurable using the MATLAB interface

Both specular and diffuse reflections are simulated

Any number of multichannel sources and receivers can be simulated

Both sources and receivers can be configured with their own directivities from a standard set (e.g. dipole, cardioid, etc.)

Source/receiver directivities can be custom definied using:

Directional impulse responses

Directional gains

Source/receiver directivities can be configured with a spherical harmonic expansion up to a set order

A set of source directivities for various orchestral instruments along with male and female speech are provided
