Distort ~ Distortion Audibility Tester

Posted by tom2tec on

DISTORT was conceived as a tool to allow one to apply a combination of complex distortions to any recorded signal, including music and hi-res recordings. DISTORT also provides simple visualization tools to examine the effects of all the distortions as they are being adjusted. The distorted sound file can be played through the available audio device drivers, from ASIO to WASAPI to Direct Sound.

The following distortions are currently provided with a variety of settings and options:

  • Harmonic distortion (THD, SINAD, THD+N)
  • Different noise floors and various spurious noise components, such as mains frequency
  • Various types of jitter, random, correlated, 1/f noise, and at various frequencies
  • Dynamic range compression effects
  • Different types of dither and bit settings

THD Meter ~ Measure Total Harmonic Distortion

Posted by tom2tec on

MathAudio THD Meter VST/AU

  • 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.
