CrossOver ~ Frequency Range Splitter


CrossOver is a plugin to split an incoming signal into several (at most 4) frequency ranges. It can be used to build your own multiband effects within a modular (sub)host environment. By using only 2 bands, you can also create bass-effects. These are effects which keep the low frequency range dry and affect only the high frequency range. The band-splitting is done by complementary pairs of Linkwitz-Riley lowpass/highpass filters, the slope of which is adjustable between 12 and 96 dB/oct. For configurations with more than 2 output bands, the signal is first split into 2 bands (low and high) and then the low or high or both bands is/are split further, thus the splitting is done in a hierarchical manner.

Key Features:

  • Splits signal in up to 4 frequency bands
  • separation between bands up to 96 dB/oct
  • flat sum due to Linkwitz/Riley filters

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.

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.
