MediaTrackSupportedConstraints: noiseSuppression property
The MediaTrackSupportedConstraints dictionary’s
noiseSuppression property is a read-only Boolean value
which is present (and set to true) in the object returned by
getSupportedConstraints() if and only if the
user agent supports the noiseSuppression
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 noiseSuppression 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.
Value
This property is present in the dictionary (and its value is always true)
if the user agent supports the noiseSuppression constraint (and therefore
supports noise suppression on audio tracks). If the property isn’t present, this
property is missing from the supported constraints dictionary, and you’ll get
undefined if you try to look at its value.
Examples
This example displays whether or not your browser supports the
noiseSuppression constraint.
<div id="result"></div>
#result {
font:
14px "Arial",
sans-serif;
}
const result = document.getElementById("result");
const supported =
navigator.mediaDevices.getSupportedConstraints().noiseSuppression;
result.textContent = supported ? "Supported!" : "Not supported!";
