I want to stop record audio from microphone when silence is detected after 2 seconds,
there is a only function to stop record on event. But how can I detect a silence for 2 seconds and stop recording?

const downloadLink = document.getElementById('download');
const stopButton = document.getElementById('stop');


const handleSuccess = function (stream) {
    const options = {mimeType: 'audio/webm'};
    const recordedChunks = [];
    const mediaRecorder = new MediaRecorder(stream, options);

    mediaRecorder.addEventListener('dataavailable', function (e) {
        if (e.data.size > 0) recordedChunks.push(e.data);
    });

    // Deve stoppare il record quando c'è silenzio
    mediaRecorder.addEventListener('stop', function () {
        $('#microfono-img').removeClass('mic_active');
        downloadLink.href = URL.createObjectURL(new Blob(recordedChunks));
        downloadLink.download = 'acetest.wav';
    });

    stopButton.addEventListener('click', function () {
        mediaRecorder.stop();
    });

    mediaRecorder.start();
};

navigator.mediaDevices.getUserMedia({audio: true, video: false})
    .then(handleSuccess);
