A few notes concerning SoundExpert ratings:

  • All devices/technologies are tested with the same testing procedure. So all ratings can be compared with each other. 
  • Ratings above 5-th grade mean that the devices/technologies have some quality headroom, their artifacts are beyond threshold of human audibility. Testing files of such devices are processed additionally - sound artifacts are amplified to the extent when they could be heard by ordinary listeners. In cases like that ratings are calculated analytically taking into account not only grades returned but also amplification applied. More details are on Testing methodology page.
  • All SoundExpert ratings exist only thanks to people like you. Consider taking part in the listening tests. It's easy and more like fun. Just download a test file below (1.5-3.5Mb, short instruction inside). Thank you in advance!
