Class AudioUnitParameterUnit

  • public final class AudioUnitParameterUnit
extends java.lang.Object
    assume kAudioUnitParameterUnit_Generic if not found in this enum [@enum] AudioUnitParameterUnit [@constant] kAudioUnitParameterUnit_Generic untyped value generally between 0.0 and 1.0 [@constant] kAudioUnitParameterUnit_Indexed takes an integer value (good for menu selections) [@constant] kAudioUnitParameterUnit_Boolean 0.0 means FALSE, non-zero means TRUE [@constant] kAudioUnitParameterUnit_Percent usually from 0 -> 100, sometimes -50 -> +50 [@constant] kAudioUnitParameterUnit_Seconds absolute or relative time [@constant] kAudioUnitParameterUnit_SampleFrames one sample frame equals (1.0/sampleRate) seconds [@constant] kAudioUnitParameterUnit_Phase -180 to 180 degrees [@constant] kAudioUnitParameterUnit_Rate rate multiplier, for playback speed, etc. (e.g. 2.0 == twice as fast) [@constant] kAudioUnitParameterUnit_Hertz absolute frequency/pitch in cycles/second [@constant] kAudioUnitParameterUnit_Cents unit of relative pitch [@constant] kAudioUnitParameterUnit_RelativeSemiTones useful for coarse detuning [@constant] kAudioUnitParameterUnit_MIDINoteNumber absolute pitch as defined in the MIDI spec (exact freq may depend on tuning table) [@constant] kAudioUnitParameterUnit_MIDIController a generic MIDI controller value from 0 -> 127 [@constant] kAudioUnitParameterUnit_Decibels logarithmic relative gain [@constant] kAudioUnitParameterUnit_LinearGain linear relative gain [@constant] kAudioUnitParameterUnit_Degrees -180 to 180 degrees, similar to phase but more general (good for 3D coord system) [@constant] kAudioUnitParameterUnit_EqualPowerCrossfade 0 -> 100, crossfade mix two sources according to sqrt(x) and sqrt(1.0 - x) [@constant] kAudioUnitParameterUnit_MixerFaderCurve1 0.0 -> 1.0, pow(x, 3.0) -> linear gain to simulate a reasonable mixer channel fader response [@constant] kAudioUnitParameterUnit_Pan standard left to right mixer pan [@constant] kAudioUnitParameterUnit_Meters distance measured in meters [@constant] kAudioUnitParameterUnit_AbsoluteCents absolute frequency measurement : if f is freq in hertz then absoluteCents = 1200 * log2(f / 440) + 6900 [@constant] kAudioUnitParameterUnit_Octaves octaves in relative pitch where a value of 1 is equal to 1200 cents [@constant] kAudioUnitParameterUnit_BPM beats per minute, ie tempo [@constant] kAudioUnitParameterUnit_Beats time relative to tempo, i.e., 1.0 at 120 BPM would equal 1/2 a second [@constant] kAudioUnitParameterUnit_Milliseconds parameter is expressed in milliseconds [@constant] kAudioUnitParameterUnit_Ratio for compression, expansion ratio, etc. [@constant] kAudioUnitParameterUnit_CustomUnit this is the parameter unit type for parameters that present a custom unit name
