MCROOMSIM

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
