    Measuring Time intervals in a signal in Matlab

    Hello everyone,

    I am encountering an unexpected problem with my data analysis. I have to analyse an acoustic signal which has a large amount of peaks. The amplitude of the peaks is not fixed nor the time of each peak. What I want to do is to measure
    1) The time interval between two peaks.
    2) The time interval that a peak lasts.

    I cannot use thresholds that easy because I want to preserve as much information as possible.

    Is there a known technique to deal with this problem? Are there any m-files available or any toolbox for such a problem?

    Please help me...This is most urgent.

    Thank you in advance.

    hi

    checkout some program like AGC (automatic gain control)
    u can even normallize the signal then keep a particular threshold
