Find Fundamental Frequency

[ChepRidwan]

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...?

Plz explain clearer ...

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

 

[javad_akhlaghi]

Fundamental Frequency in frequency domain is
frequency with highest 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???
