This program calculates the reverberation times for two methods.
The speaker on spelaer off method.

The balloon pop method.  

rt_script is the main program.  The beginning comments describe 
how the reverberation time is caculated fro both methods.  
Next the input parameters are defined.  Then an example is given.

rt_script has several input parameters.  
Typing help rt_script at the command line will provide an example.  

The file speaker_on_example.mat is created then processed.

The program reverb_time performs the actual calculations of the 
reverberation times.  It has examples for both methods.  

MEasurements of the reverberation time are generally more accurate 
when using the speaker on speaker off method.  

Test signals for the speaker on speaker off method can be created 
using the program makelNHANESNoisesm_ed, which is located on the
Matlab Central File Exchange.
