I disagree, anyone who seriously looks at these programs like wintop will
only guage the thread cpu usage that looks like it is the actual decoder
thread.  (you can view cpu usage per thread).
You never guage the interface cpu time, there is usually 3 or 4 threads in
winamp for example and the decoder thread stands out as it it usually jumps
up when you hit the play button.  All the other threads usually stay
constant (the interface and whatever else they have running). .
Myself i time the code using QueryPerformanceCounter, i dont rely on 3rd
party apps like taskmanager and wintop as i -know- the cpu counts returned
by my timing code is accurate.. it is a hell of a lot slower to decode
vorbis than mp3 and thats a fact..
