Im having trouble initializing fmod with an output rate as low as 4000 or even 8000 Hz, whereas it works perfectly with 44100 or 22050 HZ.
I need this value to be as low as possible to get as much precision as possible on the values returned by FSOUND_DSP_GetSpectrum.The precision of this function being the output rate frequency in FSOUND_Init divided by 1024.

Does anybody know why I can’t get my spectrum analysis to work with low frequencies on the output rate or any other way to gain precision on the values returned by the GetSpectrum function?
Could this matter be hardware related?

KarlKoX told me to use FFTW instead, but i still hope that fmod ex can save me… And you 😉
