Type Alias


The data type for an audio unit parameter value.


typedef Float32 AudioUnitParameterValue;


An audio unit parameter is an adjustable setting, such as gain. The parameters for Apple-supplied audio units are described in Audio Unit Parameters.

You can change a parameter value directly by calling the AudioUnitSetParameter function, or schedule a change by calling AudioUnitScheduleParameters. See also AudioUnitParameterID, AudioUnitParameter.
