Hello! all the matlab families
I fail to do my project on real time sound signal captured through microphone
data length 131072, sampling frequency 44100Hz, mono and double data type
I need to plot the data in time and frequency domain respectively and I should write a code
that displays amplitude(max) and frequency(dominant)
plz help me!

This does then assume that fft is good enough of course, there is also some functions doing AR and ARMA estimations. For example http://www.mathworks.se/help/ident/ref/ar.html
