Total Harmonic Distortion (THD) is defined as the quotient of the RMS value of all harmonics divided by the total RMS.

WinAudioMLS identifies the main frequency and tracks all harmonics. The harmonics can be emphasized by a marker. The THD value is shown in the measurement window either in % or dB.
