嗨，我正在 Cordova 开发一个混合应用程序。我想从应用程序中重现音频。我使用以下方法获得了错误：

  1. html中的音频标签
  2. 音频 javascript 对象
  3. 离子原生音频

我也尝试下载文件并复制它，但是当我可以下载时，我只能在某个文件夹上复制文件，只能复制其他文件夹。

编辑 一些代码：如果我从 chrome 或 firefox 或 VLC 打开 url，我可以正确听到声音 Il browser non supporta l'audio

Javascript代码：和上面的url是一样的

this.stream = new Audio(url);

this.stream.addEventListener('playing', (data) => {
  console.log(data);
});

this.stream.addEventListener('error', (error) => {
  console.log(error);
});
this.stream.play();

在控制台中我获得：

要录制音频，您需要使用cordova-plugin-media-capture，而不是<audio>标签。在此处阅读更多信息：https ://www.npmjs.com/package/cordova-plugin-media-capture

另外，我建议使用 Cordova 插件，为 Android 录制 .wav 格式的音频，因为 Watson Speech to Text 只接受某些音频格式。我用过这个没有很多问题：https ://github.com/petrica/wav-recorder
