I need to figure out how to detect the volume of a specific tone (~2.55KHz) in a sound clip. I hardly know anything about FFTs, but I know I don''t need a whole 1D FFT for this. I just need to find the volume of one frequency, not all frequencies hehe. So does anyone know if there is a simple formula to detect the volume of a given tone in an audio sample? Thanks!

I bet there are faster than this but - Convolution would work.

Please post if you find out a simple formula or algorithm by the way... could be very useful in many cases ...
