noiseSuppression property is a Boolean value whose value
indicates whether or not noise suppression technology is enabled on an audio track. This
lets you determine what value was selected to comply with your specified constraints for
this property's value as described in the
MediaTrackConstraints.noiseSuppression property you provided when calling
Noise suppression automatically filters the audio to remove background noise, hum caused by equipment, and the like from the sound before delivering it to your code. This feature is typically used on microphones, although it is technically possible it could be provided by other input sources as well.
If needed, you can determine whether or not this constraint is supported by checking
the value of
MediaTrackSupportedConstraints.noiseSuppression as returned
by a call to
MediaDevices.getSupportedConstraints(). However, typically
this is unnecessary since browsers will ignore any constraints they're unfamiliar with.
A Boolean value which is
true if the input track has noise suppression
false if AGC is disabled.
See the Constraint exerciser example.
