FMOD_DSP_PARAMEQ
Parameter types for the FMOD_DSP_TYPE_PARAMEQ filter.
C/C++ Syntax
typedef enum {
FMOD_DSP_PARAMEQ_CENTER,
FMOD_DSP_PARAMEQ_BANDWIDTH,
FMOD_DSP_PARAMEQ_GAIN
} FMOD_DSP_PARAMEQ;
JavaScript Syntax
FMOD.DSP_PARAMEQ_CENTER
FMOD.DSP_PARAMEQ_BANDWIDTH
FMOD.DSP_PARAMEQ_GAIN
Values
FMOD_DSP_PARAMEQ_CENTER
(Type:float) - Frequency center. 20.0 to 22000.0. Default = 8000.0.
FMOD_DSP_PARAMEQ_BANDWIDTH
(Type:float) - Octave range around the center frequency to filter. 0.2 to 5.0. Default = 1.0.
FMOD_DSP_PARAMEQ_GAIN
(Type:float) - Frequency Gain in dB. -30 to 30. Default = 0.
Remarks
Deprecated and will be removed in a future release, to emulate with FMOD_DSP_TYPE_MULTIBAND_EQ:
// Configure a single band (band A) as a peaking EQ (all other bands default to off).
// Center frequency can be used as with the old effect.
// Bandwidth can be applied by setting the 'Q' value of the new effect.
// Gain at the center frequency can be used the same as with the old effect.
FMOD_DSP_SetParameterInt(multiband, FMOD_DSP_MULTIBAND_EQ_A_FILTER, FMOD_DSP_MULTIBAND_EQ_FILTER_PEAKING);
FMOD_DSP_SetParameterFloat(multiband, FMOD_DSP_MULTIBAND_EQ_A_FREQUENCY, center);
FMOD_DSP_SetParameterFloat(multiband, FMOD_DSP_MULTIBAND_EQ_A_Q, bandwidth);
FMOD_DSP_SetParameterFloat(multiband, FMOD_DSP_MULTIBAND_EQ_A_GAIN, gain);
Parametric EQ is a single band peaking EQ filter that attenuates or amplifies a selected frequency and its neighbouring frequencies.
When a frequency has its gain set to 1.0, the sound will be unaffected and represents the original signal exactly.
