Class AVAudioUnitEQFilterType

  • public final class AVAudioUnitEQFilterType
extends java.lang.Object
    [@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 API-Since: 8.0
