Performance in SpectraLAB

To test the sound purity, I ran the SpectraLAB utility (version 4.32.17), which is none other but a FFT spectrum analyzer. This utility is shareware coming with a limited license for 30 days. You can download it from this site.

I explained the testing methodology in my previous articles, which you can find in our Multimedia section. During the tests I did my best to comply with Creative’s recommendations concerning sound card testing. The results below refer to the Line-out 1 – Line-in 3 circuit.
