This function calculates a room s impulse response for an arbitrarily positioned sound source in a rbitrarily dimensioned rectangular room, as it would be heard at an arbitrary position. The output of RIR.m is a vector and can be used as an FIR filter to produce a reverb effect. To implement this filter you will need to do a fast convolution. I have another program, FCONV.m that performs this task. It is available on the Mathworks File Exchange.



For instructions on how to use this function, put RIR.m in your Matlab work folder and type "help rir."



The physics theory used by this function is not perfect. However, the function was intended to be used for space rendering in audio productions, and for this it works pretty well.
