Performance in SpecraLAB

The second part of our today’s test session includes sound purity evaluation with the help of 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 LineIn – LineOut1 circuit.

Here are the spectrograms for Creative SoundBlaster X-Fi Fatal1ty FPS:

44,100Hz/16bit

Determining IMD at 44,100Hz/16bit
