推荐答案

有没有内置的Andr​​oid上库，支持音频混合（合并两个音频输入流转换为一个输出流）。 Java的 javax.sound 库，它支持音频混音并没有移植到Android - 有一个有趣的<一个href="https://groups.google.com/forum/?fromgroups=#!topic/android-developers/VD2V7ENFrgs">discussion与谷歌工程师戴安娜Hackborn谷歌论坛有关决定不端口 javax.sound 到Android。

There is no build-in library on Android that supports audio mixing (combining two audio input streams into one output stream). The Java javax.sound library which supports audio mixing was not ported to Android - there's an interesting discussion on Google Groups with Google engineer Diane Hackborn about the decision to not port javax.sound to Android.

看起来你不得不从头开始开发自己的解决方案。有关于如何两个音频流合并到一个上有这么几种有用的答案：

It looks like you have to develop your own solution from scratch. There are several helpful answers on SO on how to combine two audio streams into one:
