vue中使用recorder.mp3.js如何每隔5秒获取一次录音结果

要在Vue中使用recorder.mp3.js每隔5秒获取一次录音结果，你需要使用JavaScript中的定时器功能。以下是一个简单的示例代码：

<template>
  <div>
    <button @click="startRecording">Start Recording</button>
    <button @click="stopRecording">Stop Recording</button>
  </div>
</template>

<script>
import Recorder from "recorder";

export default {
  data() {
    return {
      recorder: null,
      audioChunks: [],
      timer: null,
      recordingInterval: 5000 // 5 seconds
    };
  },
  methods: {
    startRecording() {
      navigator.mediaDevices.getUserMedia({ audio: true })
        .then(stream => {
          this.recorder = new Recorder(stream);
          this.recorder.record();
          this.timer = setInterval(() => {
            this.recorder.exportWAV(blob => {
              const audioUrl = URL.createObjectURL(blob);
              // do something with audioUrl, such as playing it back or sending it to a server
            });
          }, this.recordingInterval);
        });
    },
    stopRecording() {
      clearInterval(this.timer);
      this.recorder.stop();
      this.recorder.exportWAV(blob => {
        const audioUrl = URL.createObjectURL(blob);
        // do something with audioUrl, such as playing it back or sending it to a server
      });
    }
  }
};
</script>

这个示例代码和之前的示例代码相似，但是增加了一个定时器功能，它每隔5秒调用Recorder对象的exportWAV()方法，将录音结果转换为Blob对象，并将其存储为可播放的URL。你可以在exportWAV()方法的回调函数中进行进一步的处理，例如播放录音或将其发送到服务器。当用户点击“Stop Recording”按钮时，它会停止定时器，并使用Recorder对象的exportWAV()方法将最后一次录音结果转换为Blob对象。
