Rightmark Audio Analyzer



We used Rightmark Audio Analyzer together with a loop-back cable to analyze the quality of the on-board audio solution.

Summary

Frequency response (from 40 Hz to 15 kHz), dB:+0.29, -2.52Average
Noise level, dB (A):-72.6Average
Dynamic range, dB (A):71.1Average
THD, %:0.025Good
IMD, %:0.098Good
Stereo crosstalk, dB:-73.2Good
IMD at 10 kHz, %:0.184Average

General performance: Average

The on-board audio performance of the board is ok, for the price it costs.
