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:+0.25, -0.32Good
Noise level, dB (A):-86.9Good
Dynamic range, dB (A):86.9Good
THD, %:0.0068Very good
IMD, %:0.021Good
Stereo crosstalk, dB:-87.7Excellent
IMD at 10 kHz, %:0.102Average

General performance: Good


For easier comparison we summed up the individual scores of all tested boards (1: Very poor, 2: Poor, 3: Average, 4: Good, 5: Very good, 6: Excellent). The sound quality of the AL8 on-board audio is among the best.
