The RightMark Audio Analyzer suite is designed for testing quality of analog and digital paths of any audio devices, be it a sound card, an MP3 player, a consumer CD/DVD player or an acoustic set. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms.

The ASRock Fatal1ty Professional P67 motherboard uses the Realtek ALC892 Audio Codec and received a rating of “Good” by Rightmark Audio Analyzer. This is the same rating that all of the Intel P67 boards have received whether they are using the ALC892, or the ALC889 that some of the boards are using.
