THD Meter ~ Measure Total Harmonic Distortion


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.

J-Scope ~ Oscilloscope VST Plugin


J-Scope is a VST oscilloscope plugin, which can prove invaluable to anyone who develops audio software and has a need to diagnose problems or visualise waveforms.

In operation it is very similar to a real oscilloscope, and most controls will be familiar to anybody who has used a hardware ‘scope. The addition of a control for phosphor decay time allows the examination of rapidly changing waveforms as well as slowly evolving sound envelopes.

J-Scope accepts a stereo signal, and can display it in several modes:

  • Two separate traces, L and R
  • Single trace, sum of L and R
  • Single trace, difference between L and R
  • X/Y (Lissajous) plot, L vs R
  • X/Y (Lissajous) plot, Sum(L+R) vs Diff(L-R)

Tube Preamp ~  Tube Preamp Emulation


The plugin is very unique in the sense that it gives you full control over all aspects of the modelled circuit. All values of all the capacitors, resistors etc. can be tuned by the user.

This is a free plugin. It comes in all the usual plugin formats (VST/VST3/AU/AAX), for 32 and 64 bit hosts, and for Mac Intel & Silicon.

BaxterEQ ~ Mastering & Mix Buss Shelving EQ


BaxterEQ – transparent mastering and mix buss shelving EQ

Finest tonal sweetening and finishing which always stays true to the source:

  • natural and accurate bass response
  • authentic analog style HF curve rendering
  • smoothest shelving operation

Perfectly suited for the mastering chain:

  • stepped controls throughout for repeatability and matched channel operation
  • full dual channel layout
  • full mid-side encoding support
  • per channel level control for easy A/B match

Artifact free technical design:

  • low ripple and distortion filter implementations
  • 64bit floating point internal processing
  • oversampled for superior impulse response

Meticulously selected frequencies:

  • Baxandall shelving filters
  • LF @ 74, 84, 98, 116, 131, 166, 230 and 361 Hz
  • HF @ 1.6, 1.8, 2.1, 2.4, 3.4, 4.8, 7.1, 11 and 18 kHz
  • 2-pole Butterworth filters
  • LC @ 12, 18, 24, 30, 36, 43 and 54 Hz
  • HC @ 7.5, 9, 11.1, 12.6, 16, 21, 28 and 40 kHz

An additional analog signal path emulation provides some subtle but precious stereo imaging improvements.

Correlometer ~ Multi-band Correlation Meter


Correlometer is an analog-style stereo multi-band correlation meter.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

  • 4 to 64 band correlation meter.
  • Adjustable band quality factor.
  • Adjustable averaging time.
  • Side-chain input.
  • Resizable user interface.
  • All sample rates support.
  • Zero processing latency.
  • User interface color schemes.
  • Retina and High DPI support.

MonoChannel ~ EQ & VU Meter Plugin


MonoChannel is a EQ and VU meter with basic console channel controls.

Insert MonoChannel on your audio tracks to monitor your audio signal and adjust its tonal balance. It is designed only to encourage the use of proper gain staging and audio balance workflows in digital audio. MonoChannel is NOT a distortion/saturation/console emulation plugin.

  • Classic VU meter simulation
  • +/- 24dB of gain control
  • Smooth HP filter
  • 3-band tone shaping EQ

MJUC Jr. ~ Variable Tube Compressor


MJUC jr. is the little brother of the colorful MJUC.

It’s a variable-mu design with lots of vibe, capable of smooth leveling but also heavy pumping effects. With its two gain stages and interstage transformer simulation it offers a very deep and lively soundstage.

The three-position timing switch not only controls the attack and release times of the unit, but also the slew rate of the transformers and the timing of the other parts of the circuitry, that are directly influencing the generated harmonics (saturation).

Aqualizer ~ Open Source Digital Equalizer


Aqualizer, a computer program that can be used in order to filter sound. In fact it is a digital equalizer. However, it is an equalizer for connoisseurs, so to say, as we researched how we could improve the existing equalizer to fit the needs of DJ’s and sound designers even better.
