Free Stereo Imaging Plugins

M-ST

M-ST is a free stereo imaging VST plugin developed by WOK. Compatible OS(s): Windows.

M-ST is a VST effect for quick and easy adjusting the stereo wideness of an audio signal or faking a stereo-signal from a mono input.

Unlike a mono-stereo switch the channel separation can be continuously adjusted. Above 100% the stereo signal is spread with M/S techniques first and then additionally with filter and delay lines. The resulting signal is still mono compatible.

A mono input can be turned into a fake stereo signal with similar technique.

M-ST is free and does not contain any adware, spyware, toolsbars or other annoying limitations.

_{Made with Synthedit 1.2 – no multicore bug.}

kitchen sync

kitchen sync is a free multi fx and stereo imaging and filter VST plugin developed by de la Mancha. Compatible OS(s): Windows.

kitchen sync is a tempo-synced complex LFO that modulates 4 functions: 4 state filter (LP, HP, BP, notch), Flanger, Volume and Panning.

Features:

Tempo-sync LFO with multiple waveforms modulated by second LFO and/or ADSR envelope.

Both LFOs can be synced to start cycle by any MIDI note on message.

ADSR envelope can be triggered by any MIDI note on message.

4 effects can be modulated: filter cutoff, flanger, volume, pan.

LFO 1 phase, depth and offset can be different for each effect.

LFO 2 phase, strength and origin can be different for each effect.

ADSR envelope is independent for each effect.

LFO depth can be randomised each cycle.

Full MIDI CC / MIDI learn.

Plugin wet/dry mix control .

HoRNet StereoView

HoRNet StereoView is a free stereo imaging VST, VST3, Audio Unit, AAX plugin developed by HoRNet. Compatible OS(s): Windows 64b, macOS.

HoRNet StereoView is a plugin designed to help you visualise the stereo image of your tracks.
The design of the plugin is very straightforward and easy to understand since the interface is completely occupied by the “goniometer”: an X-Y graph that displays the intensity of the signal in the stereo field.

StereoView allows you to change between two different views: the default, that we call “fireworks” that shows every sample as a straight line starting from the center, and the one we call “abstract” that connect each sample in the stereo field to the next one creating a continuous “wire”.

Another useful feature of the interface is the ability to be rescaled at will so you can resize it to fill the right spot on your screen.
A goniometer like HoRNet StereoView can be a very handy tool to directly see if your track have any anti-phase issue that may create problems when your track is played in mono, something that happens very often with mobile music listening today.

Features:

Display of stereo position and level of each sample.

Old CRT display persistence simulation for easier visualisation.

Two display modes: “fireworks” and “abstract”.

GUI can be freely rescaled.

macOS (10.7 and later) and Windows (Vista and later) support.

32 and 64-bit compatibility both on Mac and Windows.

Audio Units VST2.4, VST3, AAX format.

Harpex-B

Harpex-B is a free stereo imaging VST, Audio Unit, RTAS, AAX plugin developed by Harpex. Compatible OS(s): Windows 64b, macOS.

Harpex-B is a high-resolution surround processor for soundfield recordings. Available both as a plug-in and a stand-alone player, these tools make an already versatile surround and stereo recording technique even more interesting.

Soundfield microphones have gained a faithful following since their introduction thirty years ago and are today offered by several manufacturers. They are commonly used both as compact stereo microphones and surround microphones. They already provide more post-production possibilities than any other portable recording technique.

With the introduction of Harpex-B, several new and useful possibilities become available:

Precise rendering of the frontal stage in 5.1 surround with good channel separation.

Emulating non-coincident microphone techniques like ORTF or AB with a single, compact microphone unit.

Adjusting the ratio between reverberant and direct sound.

Emulating high-resolution 3D dummy head recordings.

Isolating sound sources through sharp spatial filtering.

B-format is the standard surround format for soundfield microphones. While conversion between B-format and other formats has always been possible, the spatial resolution has been limited to that of first-order microphones. This is insufficient for the frontal stage of 5.1, 6.1 and 7.1 speaker layouts. High-resolution processors make use of advanced signal processing that mimics the kind of spatial analysis that a human listener uses to separate and localize the many sound sources in a complex sound scene. This results in a level of channel separation and spatial definition that has never been possible before.

GWS RanPan

GWS RanPan is a free stereo imaging Audio Unit plugin developed by Ten by Ten. Compatible OS(s): macOS.

GWS RanPan is a random panning effect that is linked to tempo. Four different pan/gain behaviors are available:

Random Pan (Tempo)
Audio is panned among the channels at random in sync with a beat or fractional beat.

Random Hard Pan (Tempo)
Audio is randomly panned hard left or hard right, in sync with a beat or fractional beat.

Independent Random Gain (Tempo)
The gain of each channel is reduced by a random amount, in sync with a beat or fractional beat.

Independent Random Gain (Total)
The gain of each set of frames received for processing is reduced by a random amount. Each channel is treated independently.

GFM Psypan

GFM Psypan is a free stereo imaging VST, Audio Unit plugin developed by Games From Mars. Compatible OS(s): Windows 64b, macOS.

GFM Psypan is a dead simple and effective binaural pan effect.

When listening through headphones it puts the sound out of the head and help making the mix larger and more intrusive.

Thanks to its high quality interpolation, GFM Psypan preserves punch and clarity of even the lowest frequencies.

To provide better control over incoming stereo inputs, a stereo width control has been provided. Inter-aural Time Difference (ITD) can also be tweaked to exaggerate or decrease the delay effect.

Full Phase

Full Phase is a free stereo imaging VST plugin developed by Bass Gnomes. Compatible OS(s): Windows.

Full Phase is a unique phase based effect. It uses an inversion of a stereo channel phased against the opposite corresponding channel to isolate common stereo field characteristics. This aspect of your audio can be controlled via the “st. (stereo) field” slider.

There’s a comb filter that can add a nice character to the output via the “character” slider.

Phase shift can be accomplished using the “shift” slider in combination with the horizontal “position” slider to place the shift anywhere within the stereo field.
