Other useful information is in getMicrosecondPosition() method of the SourceDataLine object to determine the time/duration played so far .

Has anyone converted a WMA to a WAV using Windows Media Encoder? If so, do you have a short code snippet of how you did it? All samples I've seen have been for WAV to WMA, not the other way around.

Look at the Windows Media Format SDK instead.
You want to decode WMA to WAV.
The reason that all of the samples you've seen have been for WAV to WMA is that you're looking at Windows Media Encoder .

To just.
As noted, the WAV file format is very simple.
