连接两个音频Blob JavaScript [英] Concatenate two audio blobs JavaScript

问题描述

我正在使用 recorder.js 在我的网页上录制两个音频文件，然后创建录制为斑点.

I am using recorder.js to record two audio files on my web page, which then creates recordings as blobs.

一旦我有了这些音频Blob，我想将它们连接到一个轨道中.

Once I have these audio blobs I would like to concatenate them into one track.

我该怎么办?

推荐答案

如果您从麦克风缓冲区的回调中保存原始剪辑的原始PCM，我认为您只需将缓冲剪辑的数组提供给新的Blob构造函数.

if you save the raw PCM of the orig clips from the callbacks on the buffer of the mic, i think you can just provide array of bufferd Clips to a new blob constructor.

 let recordedBlob = new Blob($ArrBuff[clip1,clip2], { type: "audio/*" });
    recording.src = URL.createObjectURL(recordedBlob);
