WebSNR is a measure of the broadband noise introduced into the signal from the ADC and the sampling process. SNR compares the magnitude of the input sine wave to the sum of all other frequencies, except those representing harmonics of the fundamental. Total harmonic distortion (THD) is the ratio of the fundamental to the sum of the harmonics.
