|
|
Function to return a pointer to the current spectrum buffer. The buffer contains 512 floating<BR>
|
|
point values that represent each frequency band's amplitude for the current FMOD SoundSystem<BR>
|
|
mixing buffer. The range of frequencies covered by the spectrum is 1 to the nyquist frequency<BR>
|
|
or half of the output rate. So if the output rate is 44100, then frequencies provided are up<BR>
|
|
to 22050. (entry 511)<BR>

<H3>Return Value</H3>
|
|
A pointer to a buffer containing 512 floats.<BR>
|
|
<H3>Remarks</H3>
|
|
Note that hardware sounds, MIDI, files do not register on the spectrum graph as they are not run through FMODs DSP system.<BR>
|
|
Note that to use this you have to turn on the FSOUND FFT DSP unit. This is achieved by calling FSOUND_DSP_GetFFTUnit, then using FSOUND_DSP_SetActive to turn it on.<BR>
