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:+0.81, -4.79Poor
Noise level, dB (A):-74.8Average
Dynamic range, dB (A):73.7Average
THD, %:0.044Good
IMD, %:0.067Good
Stereo crosstalk, dB:-74.1Good
IMD at 10 kHz, %:0.315Average

General performance: Average

The on-board audio quality of the DFI NF4 Expert has improved a little bit, but it is still not comparable to the quality of other chipsets. Please note that all NVIDIA nForce 4 motherboards suffer from the low-quality audio, so there is probably not that much DFI could do to improve the sound.
