Stereoid Light stereo widener enhancer plug-in

Win 7 - Win 11
VST3 (64-bit)

OS X 10.10 – macOS 14


FREE with Stereoid


Stereoid Light – stereo upmixer, imager and enhancer – distills the essence of Stereoid, into a minimalistic plugin, while perfectly preserving its sound quality.

Stereoid Light turns your monophonic audio into a thick and fat, dimensional stereo track. Your music on steroids.

A subtle decorrelation algorithm coupled with a precise custom microtonal detuner and delay offers you a wide effect palette to enhance vocals, lead lines or complete mixes.

Thanks to its fully mono-compatible stereo widening algorithm, Stereoid Light is the tool for mono upmixing and stereo mastering.

Stereoid Light belongs to the SMARTLINE family. A series of plugins conceived according to our motto “your sound without any unnecessary complications”.
Tons of features packed in compact and ultra-usable plugins.

Stereoid Light employs principles from psychoacoustics, the science of sound perception, to create a wide and enveloping stereo image. This is achieved by combining Temporal Decorrelation, the Haas effect and Microtonal Detuning.

Temporal Decorrelation is a process that reduces the signal self similarity in the time domain. Starting from a mono source, it is possible to create other sound sources that, even if similar to the original one, have different perceptual characteristics.
Stereoid Light decorellator has been designed to be spectrally transparent. The capability of preserving the spectral character of the original audio source is of great use in stereo mastering.

When you have a signal and a delay copy of itself within 40 ms of one another, the sound is interpreted as temporal fused (the echo cannot be distinguished). Our perception fuses the original source and its repetition, making the sound wider. This is related to the Haas Effect.

Using delayed replicas in a stereo signal can however create phase and mono compatibility issues. Stereoid Light algorithm elegantly solves this problem preserving perfect mono compatibility.

The “bigger brother”, Stereoid, offers you extra control on the decorrelator frequency response, on the low frequency balance and on the amount of shifting and, additionally, it has a tube saturator.
