THD Meter

THD Meter

THD Meter is a Total Harmonic Distortion measuring tool.

Measures Total Harmonic Distortion (THD) in sound cards, speakers and headphones.
Applies matched filters for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise.
Supports microphone calibration files.
Supports full range of sample rates from 44.056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in accuracy.
