Image-source method for room impulse response simulation (room acoustics) 1.0 Description
Description: These files can be used to simulate a sound source moving in a reverberant environment and generate the corresponding samples of audio data received at one or more microphones. In addition, the user can define the desired level of environmental reverberation time in a simple and accurate manner. The audio data can be simply generated by executing the following two commands:

>> ISM_RIR_bank(my_ISM_setup, 'ISM_RIRs.mat');
>> AuData = ISM_AudioData('ISM_RIRs.mat', SrcSignalVec);

where SrcSignalVec contains the source signal, and my_ISM_setup.m contains the various user-defined parameters needed for the simulation (such as room dimension, positions of the microphones, trajectory of the sound source, desired reverberation time of the environment, etc.). The multi-channel matrix of audio data AuData contains the signals generated at each of the sensors.

These files further allow the user to define a range of simulation parameters such as automatic saving of the audio data into a .mat or .wav file, addition of white noise to the resulting signals, how much to crop the generated impulse responses, different ratios of absorption coefficients in the room, etc.

A full documentation of these files, as well as detailed explanations regarding the simulation process can be found at http://www.eric-lehmann.com

These files provide a fast implementation of the image-source model (ISM) for the simulation of room impulse responses (RIRs) in small-room acoustics. This implementation produces RIRs that are virtually identical to those obtained with the standard ISM, but the simulations are up to two orders of magnitude faster. This represents a significant advantage when computing a large number of RIRs, e.g., as in the case of moving sound sources and/or...
