Can i use Octave for acoustical measurements like Reverberation Time, etc.
Actually you can. In my job we use Octave for this.
In particular with Octave you can:
1) Generate an impulse response (IR) from any of the standard methods,
for instance, from the recording of a swept sine.
2) Once you have the impulse response, you can derive any acoustic
value, like the reverberation time, with you can deduce with the
Schroeder backwards integration method.
As for the precise formulas you have to implement, check any acoustics
textbook. It's generally straightforward. You may find some code
examples on the web http://www.mathworks.com/matlabcentral.
Hope this helps,
