Instance Property


The audio unit’s tail time, in seconds.


var tailTime: TimeInterval { get }


This property reflects the time interval between when the input stream ends or otherwise transitions to silence, and when the output stream becomes silent. This should also reflect the duration of an effect (e.g. reverberation).

This version 3 property is bridged to the version 2 kAudioUnitProperty_TailTime API.
