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
