creative's answer to the 44.1 vs. 48 flamebait.
In order to mix digital audio signals,each signal must be at EXACTLY the same sample rate, deviations of a few parts per million must be eliminated.
In the design of the EMU10K1( the soundcards synthesizer chip) a single master sample rate at which the mixer would operate had to be chosen.
The choice was between 44.1 kHz the CD standard, or 48 kHz, the professional audio and DVD standard.
48 kHz was chosen for the following reasons:
If processing incoming audio signals at nominal 48 kHz, use of 44.1 kHz causes lose of information.
In the preparation of 44.1 kHz CD's in professional studios today, 48 kHz is the preferred standard, with a final conversion to 44.1 kHz as the last step.
The almost double "guard band" (the difference between 20 kHz and the Nyquist frequency) of 24 kHz means virtually every audio process and effect performs much better at 48 kHz than at 44.1 kHz. In order to mix digital audio signals,each signal must be at EXACTLY the same sample rate, deviations of a few parts per million must be eliminated.
That said, you can actually get 44.1 out of the platinum ex, if you so desire.
I pretty much hate creative as a company, considering how they usually crap all over the pc audio market, but even I have to admit they have a fairly good product with the audigy 2 line. First PC soundcard in a LONG time I've bothered to connect to my home music rig, which is denon sources/amps and martin logan speakers.
