FMOD_DSP_TYPE_MULTIBAND_EQ - How to Equalize Magnitudes of FFT

FMOD Engine
1

Hello everybody,

I am trying to use FMOD_DSP_TYPE_MULTIBAND_EQ to create an equalizer in order to flaten the magintues of the FFT to get equal loudness in every frequency (band).
Lets say I know the frequency bands and the gain factors for each band.

However, I dont know how to set this up in the source code?

I start with:
fsystem->createDSPByType(FMOD_DSP_TYPE_MULTIBAND_EQ, &dsp_Speaker0_PN_equalizer);

–> HOW to Proceed?

Thank you very much!

You can set the various properties of a DSP (depending on the type) using:
DSP::setParameterFloat
DSP::setParameterInt
DSP::setParameterBool
DSP::setParameterData

The built in DSP’s have enum’s available for their properties to make things a bit easier:

Our DSP Plugin API docs do have some info on this topic, under ‘Plug-in Parameters’:
