Ooo. Good question. Testing....

Wow.

From the looks of it, the song file plays through the speakers at the exact right speed. It's only Winamp's time-index counter that's wrong.

In fact, if you put up the Windows clock applet (right click on the clock in the task bar and hit properties), you can watch the analog clock's secondhand move exactly in time with the beeps on the audio file no problem, whereas you can see Winamp's clock slowly drifting.

I wonder if Elperepat's plugin could somehow use the system time instead of WinAmp's time? Or perhaps detect a drift difference between the two and somehow compensate for it?
