MathAudio Releases Free THD Meter VST/AU Plugin


MathAudio has introduced THD Meter, a freeware VST and AU plugin which measures the total harmonic distortion (THD) in audio interfaces, speakers, and headphones.

THD Meter is a simple software tool designed for measuring the amount of harmonic distortion introduced to the signal by your audio equipment. This is useful in situations when you need to determine the source of unwanted noise in your studio setup, or if you simply want to evaluate the quality of your mixing gear. You can also use the plugin to compare two similar pieces of audio equipment, such as two different audio interfaces, for example. THD Meter will give you an exact total harmonic distortion (THD) value which will allow you to determine the weakest link in your audio chain.

While the plugin itself is easy to use, the measurement process does require some manual setup and preparation. The process is explained in quite a bit of detail on the product page, though, so all you’ll need is a bit of patience and a quality microphone if you want to test your speakers or headphones. An audio interface can be tested without a microphone.

If this sounds useful to you, then be sure check out MathAudio’s other products as well. They are also available for free download from the developer’s website. MathAudio offers freeware tools for equalizing headphones, microphones, and for correcting the deficiencies of room acoustics. All MathAudio software is offered in VST, VST3,  and AU plugin formats for compatible digital audio workstations on PC and Mac. Some of their software tools are also available as plugins for the foobar2000 audio player.

THD Meter is available for free download via MathAudio (860 KB download size, ZIP archive, 32-bit & 64-bit VST/VST3/AU plugin formats for Windows & MacOS).

  1. Is it possible to route the plugin within a DAW? For example; to measure the THD of a simulated recording chain (with saturation and compressors and whatnot?)
