Hi,

I have designed a system/algorithm which attenuates speech signal. Now I would like to calculate using Matlab - from my system's output speech signal (a wav file) - the power of original signal and power of processed signal and see how fast it is attenuated let say -10dB. I expect that would happen in some tens (or hundreds) of msec's. What would be convenient way to calculate the powers and get the result? Best would be if I could plot the powers graphically. Any .m code example for this available?

If I calculate signal powers frame-by-frame (let say 10ms frames), the speech signal is changing too fast and not that visual?

Thanks,

Micke

hello

can you share the wav files as well ?

Sorry for delayed response but I was able to confirm from time domain signals that my algorithm is fast enough and gave up from this deeper checking as it is challenging to calculate it after all. Thanks for the help.
