将两个音轨合并为一个音轨

如何解决将两个音轨合并为一个音轨

为了将整个合并的音频添加到视频轨道，我在将两个音频轨道合并为一个轨道时遇到问题。

我如何将它们合并为一条轨道，有人可以帮我吗？

解决方法

我能够通过使用Web Audio API来做到这一点。我从两个流中获取了音轨，并使用音频上下文将它们合并为一个。

var OutgoingAudioMediaStream = new MediaStream();
OutgoingAudioMediaStream.addTrack(OutgoingStream.getAudioTracks()[0]);

var IncomingAudioMediaStream = new MediaStream();
IncomingAudioMediaStream.addTrack(IncomingStream.getAudioTracks()[0]);

const audioContext = new AudioContext();

audioIn_01 = audioContext.createMediaStreamSource(OutgoingAudioMediaStream);
audioIn_02 = audioContext.createMediaStreamSource(IncomingAudioMediaStream);

dest = audioContext.createMediaStreamDestination();

audioIn_01.connect(dest);
audioIn_02.connect(dest);

var FinalStream = dest.stream;

这很好用。
