如何在ReactJS中将blob转换为MP3？

const reader = new FileReader();
reader.readAsArrayBuffer(blob);

reader.onload = function(event) {
  const arrayBuffer = event.target.result;
  const newBlob = new Blob([arrayBuffer], { type: 'audio/mp3' });
  // 这里可以对新的Blob对象进行处理或者使用
}

npm install file-saver

import { saveAs } from 'file-saver';

// ...

reader.onload = function(event) {
  const arrayBuffer = event.target.result;
  const newBlob = new Blob([arrayBuffer], { type: 'audio/mp3' });
  saveAs(newBlob, 'audio.mp3');
}
