Entry-level Multi-channel Sound Card: Hercules Gamesurround Muse 5.1 DVD

Total Harmonic Distortion

The following test measured the total harmonic distortion, or THD. It is a study of the audio fidelity of the card - the harmonics that appear on the card when one sends a single but strong sinusoidal sound wave (-3 dB) to the card. The result is more or less average, but acceptable, at about 0.07% on both channels.
