Hi,

I have an old version (1.5) of the SoundBlaster soundcard from Creative Labs
for PC and I would like to do accurate frequency measurements. As a first 
experiment I tried to record a 440 Hz tuning fork at 11025 Hz sampling 
frequency, but I got a frequency of about 436 Hz (give or take 0.7 Hz).

I therefore wonder about the accuracy of the sampling frequency and other
data on this model (1.5) and if they are better on later versions.


By the way: does anyone know the email-address to Creative Labs?

Thank you for your answers!
