Get frequency and amplitude from an audio sample I'm wondering how can i get the frequency and the amplitude from a 16 bits sample.
I have actually an array of 16 bits signed int and I would like to get the frequency and the amplitude of each sample. I've heard from FTT and stuff but I'm kinda new to signal processing about audio.
Any advice would be appreciated,

Thanks.

That makes no sense. A single sample is just a number. 

A number doesn't have a frequency.

The number itself is the amplitude.
