autoGainControl property

bool get autoGainControl

The MediaTrackSupportedConstraints dictionary's autoGainControl property is a read-only Boolean value which is present (and set to true) in the object returned by MediaDevices.getSupportedConstraints if and only if the supports the autoGainControl constraint. If the constraint isn't supported, it's not included in the list, so this value will never be false.

You can access the supported constraints dictionary by calling navigator.mediaDevices.getSupportedConstraints().

The autoGainControl constraint indicates whether or not the browser offers the ability to automatically control the gain (volume) on media tracks; this obviously is contingent on whether or not the individual device supports automatic gain control as well; it's typically a feature provided by microphones.

Implementation

external bool get autoGainControl;
set autoGainControl (bool value)

Implementation

external set autoGainControl(bool value);
