Displays stereo angle histogram

Features:

• peak, hold and energy indicator

Correlation, balance and azimuth meter.

Bispectrum Analyser

Effects

Thiran Delay

Delay effect with allpass fractional delay algorithm.

Features:

• linked sliders with 6 unit types
• feedback azimuth rotation
• sidechain delay modulation
• sine wave delay modulation
• parameter smoothing

M-Flanger

Combination of flanger and stereo widener.

Features:

• high quality fractional delay algorhithm
• feedback rotation
• three stereo widening modes

Vowel Filter

Chebyshev Saturator

Utility for emphasizing given harmonics.

Features:

• chebyshev polynomials from 1st to 9th order
• harmonic mode - adjust the amount of even and odd harmonics
• rectifier
• DC filter
• GFX signal transfer function viewer

Transient Split

A tool that allows you to extract transients or stationary signals from the input signal.

STFT Frequency Shifter

A plug-in for performing single-sideband modulation (SSB)

Features:

• FFT brickwall antialiasing filter
• linear phase processing
• spectrum reverser
• pre-differentiator
• parameter smoothing

Cepstrum Lifter

Features:

• long-pass, short-pass and moment-reject liftering
• cepstrum analyser with peak detection

STFT Extractor

Utility for attenuating partials with given azimuth and phase difference in stereo field. Can be used for example as a reverb remover (but only works if the reverb is uncorrelated between channels).

Stereoscope EQ

STFT Extractor + GUI

Controls:

• click+drag to change filter position
• scroll to change stereo width,
• ctrl+scroll to change frequency bandwidth

Coherent Extractor

A tool for separating a coherent signal from a stereo signal.

M-Phaser

Phaser based on IIR Hilbert transformer with three stereo widening modes

Generators

Logistic Noise Generator

Noise generator based on the logistic map equation.

Stern-Brocot Stereochord

Triad generator with two-dimansional snap-to-integer-ratio control panel.

Features:

• snapping to simplest integer ratio with variable error value
• multiple waveforms to choose from
• oscilator frequency smoothing
• ratio and frequency readouts

Farey Tetrad Spiral

Four-oscillator generator with spiral visualization.

Features:

• visualization of combination tones (F1-F2, 2F1-F2, F1-2F2)
• colors indicating chroma of musical note
• display of overtones, undertones, upper and lower Farey sequences
• frequency readout for every tone and combination tone
• parameter smoothing
• multiple waveforms

DPOAE Canceller

Generator of two periodic signals and three phase-locked signals for canceling otoacoustic emissions (F1-F2, 2F1-F2, F1-2F2).

Features:

• three methods of changing frequency
• tone and combination tone visualization
• visualization of undertones and overtones of main two tones

Utilities

Crossfeed

Utility plugin inspired by the Goodhertz CanOpener

Features:

• three crossfeed algorhithms
  • Filter - removes stereo information from lower frequency band
  • Delay - standard crossfeed algorhithm
  • Allpass - interaural phase difference mapping using the allpass filter - has worse spatial reproduction, but does not affect the timbre of the upper frequency bands
• delay value readouts
• speaker angle visualization
• Equal-loudness contour compensation (approx. ISO 226-2003)

Proximity Processor

A tool for positioning sound object in stereo field.

Features:

• MCP dockable GUI
