RightMark Audio Analyser (RMAA)
RMAA suite is designed for testing quality of analog and digital paths of any audio device. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. A more common mark is also provided for those unfamiliar with measured technical parameters. Available here. We run the RMAA test using a 3.5mm to 3.5mm cable connecting the line out to the line in to test the quality of the motherboard audio codec not any external audio devices. We run the complete playback and recording test at default settings and then get RMAA to interpret the results giving the below outputs. We sync the playback and recording audio devices to the same setting as the test for accurate results.
16 Bit, 44KHz (DVD Quality)
16 Bit, 96KHz (Studio Quality)
24 Bit, 96KHz (Studio Quality)
A pretty good rating for a mid-range motherboard.
