[@enum] AVAudioUnitEQFilterType

Filter types available to use with AVAudioUnitEQ.

Depending on the filter type, a combination of one or all of the filter parameters defined in AVAudioUnitEQFilterParameters are used to set the filter.

AVAudioUnitEQFilterTypeParametric Parametric filter based on Butterworth analog prototype. Required parameters: frequency (center), bandwidth, gain

AVAudioUnitEQFilterTypeLowPass Simple Butterworth 2nd order low pass filter Required parameters: frequency (-3 dB cutoff at specified frequency)

AVAudioUnitEQFilterTypeHighPass Simple Butterworth 2nd order high pass filter Required parameters: frequency (-3 dB cutoff at specified frequency)

AVAudioUnitEQFilterTypeResonantLowPass Low pass filter with resonance support (via bandwidth parameter) Required parameters: frequency (-3 dB cutoff at specified frequency), bandwidth

AVAudioUnitEQFilterTypeResonantHighPass High pass filter with resonance support (via bandwidth parameter) Required parameters: frequency (-3 dB cutoff at specified frequency), bandwidth

AVAudioUnitEQFilterTypeBandPass Band pass filter Required parameters: frequency (center), bandwidth

AVAudioUnitEQFilterTypeBandStop Band stop filter (aka "notch filter") Required parameters: frequency (center), bandwidth

AVAudioUnitEQFilterTypeLowShelf Low shelf filter Required parameters: frequency (center), gain

AVAudioUnitEQFilterTypeHighShelf High shelf filter Required parameters: frequency (center), gain

AVAudioUnitEQFilterTypeResonantLowShelf Low shelf filter with resonance support (via bandwidth parameter) Required parameters: frequency (center), bandwidth, gain

AVAudioUnitEQFilterTypeResonantHighShelf High shelf filter with resonance support (via bandwidth parameter) Required parameters: frequency (center), bandwidth, gain
