Pre-recorded Audio Playback

Describes how to incorporate playback of pre-recorded audio files during WebRTC calls.

This section explains how to integrate playback of pre-recorded audio files during WebRTC calls within a CRM application. It includes the implementation of functions to play, pause, and stop the playback of the audio file. Additionally, it covers muting and unmuting the user's microphone during audio playback.

Code snippet:

function pausePlayback() {
    if (preRecordedAudioElement && !preRecordedAudioElement.paused) {
        preRecordedAudioElement.pause();

        // Re-enable the user's microphone
        if (userStream) {
            userStream.getAudioTracks().forEach(track => {
                track.enabled = true;
            });
        }
    }
}

// Function to mute the user's microphone during playback
function muteMicrophone() {
    if (userStream) {
        userStream.getAudioTracks().forEach(track => {
            track.enabled = false;
        });
    }
}

// Example of how to trigger the playback during the call
document.getElementById('playButton').addEventListener('click', function() {
    // This would need to be adapted based on your specific scenario
    // For example, you might initiate a call when the button is clicked
    // or trigger playback during an ongoing call
});

// Example of how to pause the playback during the call
document.getElementById('pauseButton').addEventListener('click', pausePlayback);

// Example of how to mute the microphone during the call
document.getElementById('muteButton').addEventListener('click', muteMicrophone);
