The RTCPeerConnection method getSenders() returns an array of RTCRtpSender objects, each of which represents the RTP sender responsible for transmitting one track's data. A sender object provides methods and properties for examining and controlling the encoding and transmission of the track's data.


var senders = rtcPeerConnection.getSenders();

Return value

An array of RTCRtpSender objects, one for each track on the connection. The array is empty if there are no RTP senders on the connection.

The order of the returned RTCRtpSenders is not defined by the specification, and may change from one call to getSenders() to the next.


In this example, a setMuting() function is shown. This function takes as input an RTCPeerConnection, pc, and a Boolean, muting. The function gets the list of the peer connection's senders and iterates over every sender, setting the corresponding media track's enabled to the inverse of the specified muting.

function setMuting(pc, muting) {
  let senderList = pc.getSenders();

  senderList.forEach(sender) {
    sender.track.enabled = !muting;
