ASUS Xonar D2 7.1 Channel Audio Card RMAA 6.0.5 Test Guide and Results

Short Description
The Xonar D2 driver CD includes RightMark Audio Analyzer (RMAA) v.5.6, popular software intended for testing the quality of audio equipment, be it a sound card, portable MP3 player, consumer CD/DVD player, or a speaker system. However, the latest RightMark Audio Analyzer v6.0.5 is available now. This document describes the test guideline with RMAA v6.0.5 and the complete test results by updated Xonar D2 driver package (8.17.20 or later), which improves RMAA MME test quality inherently limited by Windows to faithfully present Xonar D2’s hardware quality. The measurements are conducted by playing and recording test signals, and using frequency analysis algorithms. The following provides a step-by-step loop-back test guide for your Xonar D2 audio card.
