How to get the frequency of an audio file and how to separate the low
and high frequency of an audio file
and high frequency of an audio file
I don't know. It isn't a C++ problem, try a group where audio files areUdhay said:How to get the frequency of an audio file and how to separate the low

So, use advices of the other posters and use FFT to decompose
sound to its frequency components [spectral analysis], deamplify
the frequencies you don't want and compose your sound back again
using only the frequency components you want [they're sines,
you know].

No no ... if you want to create a filter (filter out a certain
set of frequencies) then create a low-pass/high-pass/band-pass
filter. There is no need to do it in the frequency domain.
FFT's are relatively expensive computationally.

Oh, I didn't know that can be done better. Can you tell me
something more about it? [maybe on priv, if it's NTG here].
