hey guys i''ve got a very similar assignment but in mine i've to distinguish between different species of cicada's (some type of insect) based on the noise it makes .i.e. different species makes different noise and based on that i've got to recognise it.......so what i was thinkin is to store some samples in the first place and the perform the fast fourier transformation of it.........now since i'll only be tested on the spices that i've stored so when the user plays a random clip it will perform the FFT of it and compare it to the already stored ones...........Now i know how to perform the FFT but the comparison part seems to be a problem.......can any one please help
