Discussion

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.
