推荐答案
Android 上没有支持音频混合(将两个音频输入流合并为一个输出流)的内置库.支持音频混合的 Java javax.sound 库未移植到 Android - 有一个有趣的 与 Google 工程师 Diane Hackborn 在 Google 网上论坛讨论关于不将 javax.sound 移植到 Android 的决定.
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.
