rt_script.m is the main program. It produces a text file and a pdf file to document the reverberation time estimate. Two measurement methods can be used 1) speaker on-speaker off method, and 2) balloon pop method.

A basic procedure for the measurement two methods is given in the Readme file. The speaker on-speaker off method has been found to be far more accurate than the balloon pop method. Teh balloon pop method can often have more than 50% error below 1000 Hz.

reverb_time.m calculates the reverberation times for 1/3 octave band time records. Time records using the random time test signals from makelNHANESNoisesm_ed.m from (Also on Matlab Central File Exchange) are ideal for reverberation time measurements using the speaker on- speaker off method.

With the balloon pop method, the same file can be processed several times to roughtly estimate the reverberation time in each 1/3 octave band.
