[英]Possibility to record playback of browser audio element using JavaScript?
I am currently working on a simple audio project which uses HTML / JS audio elements to play audio using buttons.我目前正在开发一个简单的音频项目,它使用 HTML / JS 音频元素使用按钮播放音频。
Is it somehow possible to record that audio being played instead of recording the microphone (by using the MediaRecorder API)?是否可以录制正在播放的音频而不是录制麦克风(通过使用 MediaRecorder API)?
After following the steps provided by lawrence-witt , I figured it out.在按照lawrence-witt提供的步骤之后,我想通了。 Here an example for everyone trying to achieve the same:
这是每个试图实现相同目标的示例:
const audioContext = new AudioContext();
const destination = audioContext.createMediaStreamDestination();
const mediaRecorder = new MediaRecorder(destination.stream);
// array of 'new Audio()' elements
audioArray.forEach(audio => {
let stream = audioContext.createMediaStreamSource(audio.captureStream());
stream.connect(destination);
})
mediaRecorder.start();
