SHEPPi Spatial Enhancer

SHEPPi Spatial Enhancer is a free stereo imaging VST plugin developed by Open Ambience Project. Compatible OS(s): Windows.

SHEPPi (Stereo Haas Effect Ping Pong Inverter) is a stereo image enhancement tool modeled after the K-Stereo Ambience Processor by Algorithmix. SHEPPi imparts a subtle, natural sense of space thanks to a combination of EQ’able synthetic early reflections, M-S widening and inverted stereo delay feedback.

This plug-in has been enhanced for both track insert as well as aux send applications, making it an excellent tool for both mastering and stereoizing purposes.

SHB-1

SHB-1 is a free amp simulator VST, Audio Unit plugin developed by Ignite Amps. Compatible OS(s): Windows 64b, macOS.

SHB-1 is based on the real SHB-1 “Extreme Bass Head”, built by Ignite Amps for Federico Fulceri, bass player of the Italian thrashers Subhuman, featuring 6 triode stages and a 1300W Class D power-amp.

Every single component in the signal path of the real analog circuit has been taken into account and modeled in the best possible way to match the original sound, keeping an eye on CPU performance and real-time playability at the same time.

SHB-1 is meant to be used as a bass amplifier for live playing and jamming, tracking or mixing inside hosts capable of VST or AU plug-ins support.

Main Features:

Dynamic 12AX7 / ECC83 coupled triode stages analog modeling.

Mono / Stereo processing support.

Selectable oversampling rate (up to 8x).

Global input / output level controls.

Double precision (64-bit) floating point mathematical model.

Fully automatable controls.

Shattersync

Shattersync is a free delay VST plugin developed by Pluggotic. Compatible OS(s): Windows.

Shattersync is a modified version of DarkWare’s Shattershot Lite VST. It’s a stuttering/repeating FX based on modulated delays triggered by a step-sequencer. Repeats of all sorts, glitches and noises, random events and singular/casual phrases re-arrangements can be achieved quickly, on both melodic and rhythmic material.

The alterations of the original design are focused on:

New modulations, now host-synchronized.

A new independent stuttering FX in the signal chain.

MIDI implementation.

New GUI.

SGA1566

SGA1566 is a free overdrive and saturation VST, Audio Unit plugin developed by Shattered Glass Audio. Compatible OS(s): Windows 64b, macOS.

SGA1566 preamplifier is loosely based on a single channel all tube vintage preamplifier. To achieve the most authentic analog sound, the whole circuit is simulated in real time using the high performance circuit simulator. This level of sound fidelity comes at a price of high CPU utilization. For cases where such a CPU hit is prohibitive, we have added a model that is significantly less CPU intensive but slightly less accurate than the circuit simulation.

Use SGA1566 preamp to add warmth to a track, as a saturation compressor, or to add “dirt” with tube overdrive.

Features:

Authentic analog sound through real-time high-performance circuit simulation.

Preamp featuring two 12AX7 voltage amplification stages.

CPU friendly model of the circuit.

Two-band active Baxandall EQ that can be placed either at the beginning or at the end of the signal chain.

Up to 4x oversampling.

Mono or stereo processing mode.

sg-uglyverb

sg-uglyverb is a free reverb VST plugin developed by Synthgeek. Compatible OS(s): Windows.

There are times when I want a reverb for its smearing, tail-producing qualities, but a regular reverb isn’t ugly enough. This was created to solve that problem. It sounds just like the name implies, and sometimes that’s just what the situation calls for.

sg-tadf1

sg-tadf1 is a free filter and ring modulator VST plugin developed by Synthgeek. Compatible OS(s): Windows.

This is a dual filter bank with a ring modulator and distortion. For modulation, there are 2 LFOs and 2 step sequencers, plus the combiner module as seen in the noisebots. “TADF” stands for Total Audio Destruction Filter.

sg-sineshaper

sg-sineshaper is a free waveshaper VST plugin developed by Synthgeek. Compatible OS(s): Windows.

Sine-based waveshaping distortion. A rather nasty effect, especially with lower “divisor” values. Values of 2 or higher are closer to a standard soft-clipping transfer function. Use the input level to control drive.
