I use FFT for processing audio data. I was find 1 frequency for 1 point. How we can find the fundamental frequency?. Is the highest Amplitudo? or what...?

Foundamental frequency related to frequency , not amplitude.
but if more than one foundamental present at a time,
you can focus one with higher amplitude.

If you're processing an audio file with music the fundamental should be the lower frequency.

Moreover... if the audio data relates to a multiple sources (3-4 sources: guitar, bass, ecc...) what fundamental are you looking for???
