将采集的音频数据通过WebSocket发送给另一端，并实时播放采集的声音的示例代码。请注意，这个示例是一个简化的版本，实际应用中可能需要更多的处理和细节。

首先，确保您已经建立好WebSocket连接，并在适当的地方初始化WebSocket对象。然后在获取到音频数据后，将数据通过WebSocket发送给另一端，接收端将收到音频数据并进行播放。

window.navigator.getUserMedia(
    {
        audio: true
    },
    function(stream) {
        var audioContext = new (window.AudioContext || window.webkitAudioContext)();
        var analyser = audioContext.createAnalyser();
        analyser.smoothingTimeConstant = 0.8;
        analyser.fftSize = 2048;

        var bufferLength = analyser.frequencyBinCount;
        var microphone = audioContext.createMediaStreamSource(stream);

        microphone.connect(analyser);
        var processor = audioContext.createScriptProcessor(2048, 1, 1);
        processor.connect(audioContext.destination);

        // WebSocket初始化
        var ws = new WebSocket('ws://your_websocket_server_address');

        processor.onaudioprocess = function(event) {
            var array = new Uint8Array(analyser.frequencyBinCount);
            analyser.getByteFrequencyData(array);
            var average = getAverageVolume(array);
            
            // 发送音频数据到WebSocket服务器
            ws.send(JSON.stringify({ type: 'audioData', data: array }));

            SW.setAmplitude(average / 140);
        };
    },
    function() {
        console.log(1);
    }
);

然后在另一端，您可以使用WebSocket来接收音频数据并进行实时播放与录音。以下是一个示例的接收和播放代码：

var ws = new WebSocket('ws://your_websocket_server_address');
var audioChunks = []; // 用于存储录音数据块

ws.onmessage = function(event) {
    var data = JSON.parse(event.data);
    if (data.type === 'audioData') {
        var audioContext = new (window.AudioContext || window.webkitAudioContext)();
        var source = audioContext.createBufferSource();
        var buffer = audioContext.createBuffer(1, data.data.length, audioContext.sampleRate);
        var channelData = buffer.getChannelData(0);

        for (var i = 0; i < data.data.length; i++) {
            channelData[i] = data.data[i] / 128.0 - 1.0;
        }

        source.buffer = buffer;
        source.connect(audioContext.destination);
        source.start();
         audioChunks.push(new Float32Array(data.data));
    }
};
// 开始录音
function startRecording() {
    audioChunks = []; // 清空之前的录音数据
    var mediaRecorder = new MediaRecorder(stream);

    mediaRecorder.ondataavailable = function(event) {
        if (event.data.size > 0) {
            audioChunks.push(event.data);
        }
    };

    mediaRecorder.onstop = function() {
        var audioBlob = new Blob(audioChunks, { type: 'audio/wav' });
        var audioUrl = URL.createObjectURL(audioBlob);
        var audio = new Audio(audioUrl);
        audio.play();
    };

    mediaRecorder.start();
}

// 停止录音
function stopRecording() {
    mediaRecorder.stop();
}
