MediaTrackConstraints.noiseSuppression - Web APIs 编辑
The MediaTrackConstraints
dictionary's noiseSuppression
property is a ConstrainBoolean
describing the requested or mandatory constraints placed upon the value of the noiseSuppression
constrainable property.
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.
Noise suppression is typically provided by microphones, although it can be provided by other input sources as well.
Syntax
var constraintsObject = { noiseSuppression: constraint }; constraintsObject.noiseSuppression = constraint;
Value
If this value is a simple true
or false
, the user agent will attempt to obtain media with noise suppression enabled or disabled as specified, if possible, but will not fail if this can't be done. If, instead, the value is given as an object with an exact
field, that field's Boolean value indicates a required setting for the noise suppression feature; if it can't be met, then the request will result in an error.
Example
See Example: Constraint exerciser in Capabilities, constraints, and settings for an example.
