reverberation in matlab

Hi I have a broadband signal x(t) as

x = randn(1,100); Fs = 48e3;

Do we have any inbuilt function or a standard procedure for adding reverberation to the signal(say 3 copies).

The application is for audio source localization.

Cheers

Is your signal definitely broadband? Please see my discussion of the term at http://www.mathworks.com/matlabcentral/answers/26278-how-to-add-delay-to-a-signal

Yeah, randn(1,100) can be considered as a broad band signal, right? I assume a frequency of 48e3;

To add delay, I take the fft and multiply it with exp(-2*pi*Fs*Td) (Td is time delay) and inverse FFt the result to obtain the time domain delayed signal.

Or we may consider other audio signals as well, right!
