The minimum hardware you need is an A/D converter so that you can acquire the signals and a D/A if you want to send it back to analog. Special processing hardware is need only if you want realtime or fast processing.

There's a "new" technique called Wavelet Transform that is better suited to note recognition than FFT. Oversimplifying, it's like a short time Fourier transform but with constant "Q" bands instead of constant bandwith (that is the frequency resolution is uniform on a log scale).
