How do I mix multiple audio streams into a single recorded stream with Java?

Question

Using Java Sound, Tritonus and JavaFX, how can I intercept data sent to the speakers and record it as a file? For example, I want to mix JavaFX media player audio streams (and/or Java Sound audio streams) into a single "wav" file in the same way a recording studio environment might do it.
