hi, i'm trying to make audio fingerprint systems, first step what i should do is to process audio signal by a first-order digital network in order to spectrally flatten the signal. How it should look in matlab?

for example
[wav, fs, nbits]=wavread('audio.wav'), what i should do next in order to process it by first-order digital netwrok?

Thanks in advance,
Juozas
