The sample frequency of CDs are 44.1kHz so the theoretical maximum frequency they can record is 22.05kHz due to the 'Nyquist frequency' (http://en.wikipedia.org/wiki/Nyquist_frequency). So yea something is screwy with the direct sound windows component. I have a x-fi card too and I turned off all effects also, I think most of the effects are processed in the sound card x-fi DSP chip so it shouldn't affect the direct sound recording but better to be safe. The latest MP3 encoders have gotten pretty good and I can't really hear any difference at 256k bit-rate or above. I stay far away from the MP3 debates. I am a perfectionist and just like the idea of storing data in it's original bit-perfect form even if I do not own the equipment to hear the difference. I buy a CD once, I rip the data in a lossless format so I will always have the same quality recording I purchased. I use the spectrum visualization in foobar2000 for quick peaking at frequency cutoffs, I then go into a wav editor and load up a recording to get an idea how an album was mastered. It is a same that everything is mastered now to be as 'loud as possible' (http://en.wikipedia.org/wiki/Loudness_war) but I am getting off the subject. -- LukeS ------------------------------------------------------------------------ LukeS's Profile: http://forums.slimdevices.com/member.php?userid=32128 View this thread: http://forums.slimdevices.com/showthread.php?t=48260
