ITDPanner

ITDPanner is VST3 panner plugin specialized to control the pan of stereo sound source without sound quality degradation. ITDPanner never mix left channel and right channel, so it has no sound quality degradation caused by interference of sound. It is based on ITD(Interaural Time Difference)control and balance control.

QUO stage panner

Quo is simple "stage" panner. It place two virtual microphones to simulate virtual stage. It does not simulate realistic room acoustics but rather focus on audible effect usable on headphones and loudspeakers.

It is able to use mono or stereo audio source. For stereo source it allows you to do true stereo panning.

Features:

- Haas Cross Dual Delay for creating stereo audio from mono
- Interaural time difference - difference in arrival time of a sound between two ears.
- Distance daley to simulate sound delay based on distance
- Boost Mic allow you to change linear decay to adjustable logarithmic decay
- Absorption of high-frequencies in air
- Reflection with adjustable intesity.

- XY pad for positioning audio source on virtual stage
- CTRL+drag on pad allows you to place source on 10x10 grid tile
- CTRL+right mouse click set sliders to 50%
- double left click set sliders to zero.

HY-Plugins has released HY-TP2, an update of the freeware tremolo and auto-pan effect by HY-Plugins.HY-TP2 comes with an improved, resizable user interface, two additional LFO shapes and a LFO phase knob for precise timing adjustments. The envelope follower and soft clipper from the previous version are no longer found in version 2.

Located on the left-hand side of the user interface is the Mod Wave section with the LFO waveform selection panel (sinewave, triangle, ramp up, ramp down, log up, log down, square, and random), a phase adjustment knob, and a smoothing knob which smooths out the shape of the selected waveform.

The Tremolo/Panner section features the modulation rate, modulation depth, and modulation width knobs. The width knob affects the plugin’s behavior as a tremolo or a stereo auto-pan effect. The filter section features a pair of one filters (low-shelf and high-shelf). Finally, the Output section features the output volume dial.

B. Serrano - IO effects

IO is a set several effects .
These effects are driven by a sophosticated GUI envelope.
Default time value is in second. Duration is theorically infinite
So this enveloppe can run from 1 nanosecond to several minutes, hours...

Filter, phase, level, pan, ring-modulation.
