Reverbering

Reverbering is a free reverb VST plugin developed by NUSofting. Compatible OS(s): Windows.

Reverbering is a simple reverb effect sporting low CPU usage and two features not normally found in other similar effects – Noise and Grain – of course these can be set to zero for a clean reverb effect.

Features:

Noise: this adds a filtered noise sound to the decay.

Grain: this saturated the audio signal for a vintage feel.

MIDI learn on every parameter, menu by right click.

Reverbering use the same optimized algorithm featured in Modelonia.

100% skinable.

Reverb-O-Matic

Reverb-O-Matic is a free reverb VST plugin developed by Hazelden. Compatible OS(s): Windows.

Reverb-O-Matic is a reverb plug-in based on Moorer’s reverb model (from ‘About this reverberation business’).

It uses 6 comb filters in parallel followed by a single all-pass filter. The initial parameter settings are those recommended by Moorer for a sampling rate of approx. 44.1Khz. Each comb filter has a single-pole low-pass filter in its feedback loop to approximate the absorption of materials (i.e. walls) and these are labeled LP coefficients on the custom GUI.

RetroBandLite

RetroBandLite is a free overdrive and saturation VST plugin developed by Michael Kingston Productions. Compatible OS(s): Windows, macOS.

RetroBandLite is a free cut down version of the commercial
RetroBand. There are no time or preset usage limitations, but many of the advanced features of the full version are missing and RetroBandLite processes everything as mono.http://www.michaelkingston.fi/

resonance_chung

resonance_chung is a free reverb VST plugin developed by NGUYEN.Chung. Compatible OS(s): Windows.

resonance chung is a free VST plugin effect compatible with VST steinberg, fb_chungVST, midipiano_chung, freemp3_chung, dsp_chung music plugins support.
It aims to simulate the increase of reverberation with the number of played notes like in a real acoustic piano. a quick fft small fourier transform is used to estimate a number of played notes and modify the reverb rate in real time.
Is written in easy fast freebasic.

RESOM

RESOM is a free resonator VST, VST3 plugin developed by WOK. Compatible OS(s): Windows 64b.

RESOM is a free resonator audio effect.

It features 6 resonator units (2*3, stereo) with 4x oversampling, tuned as a “power chord”.

Overall tuning can be adjusted on the GUI or with MIDI keys.

The signal can also be send to bandpass filters first before going to the tuned resonators, there is a fine detuning function and stereo spread.

RESOM is available for Windows as a 32-bit VST plugin and 64-bit VST3 (experimental) from WOK.

Update v1.1
– shows up as effect now, not synth
– Mac 64-bit VST3 version included (experimental)

Update v1.2
– 64-bit version wrong resonator calculation.

Rescue MK2

Rescue MK2 is a free exciter VST plugin developed by Variety Of Sound. Compatible OS(s): Windows.

Rescue MK2 is an analog style modelled signal designer. It is a sophisticated mid/side based transient processing device which not only allows detailed ‘3D’ imaging control but also fancy transient compression and distortion with dynamics that remains vibrant and alive.

Res8

Res8 is a free filter Audio Unit plugin developed by Music Unfolding. Compatible OS(s): macOS.

The Collective 8 Audio Unit Bundle consists of three Audio Units: F8-V2, Mod8 and Res8. All three share a similar amplitude modulation sequence configuration. The audio stream is copied into 8 identical streams and an amplitude modulation pattern can be applied to each stream. The amplitude modulation patterns can be drawn to any shape, with an-easy-to use editing environment that automatically appears when hovering over the patterns with a mouse. Each stream also has filters or effects applied to it individually. The streams are then mixed back together.

The plug-ins:

F8-V2 has LFOs, which are applied to highpass, bandpass or lowpass filters.

Res8 has a choice of a driven, nonlinear, multi-stage filter or formant filters that can be independently applied to each audio stream.

Mod8 has a range of modulation effects like vibrato and ring modulation. It also has echo, reverb, sub-octave, and pitch shifting.

The result is up to 8 different effects running all at the same time, each with its own settings and amplitude sequences. This layering gives unlimited options to create incredibly interesting effects, from intricate and wild effects, to rich, textured reverb, echo, chorus-type effects. The Collective 8 Audio Units come with hundreds of presets. Amplitude modulation patterns can be copied and pasted within each AU or between them.

Regen

Regen is a free looper VST plugin developed by ToneCarver. Compatible OS(s): Windows.

Regen is at its heart a looper plugin (a la Frippertronics) that is well suited for ambient/textural/soundscape type layering. It can be a simple looper but also offers deeper dive controls to modify playback of recorded material.

It features four independent loopers (“tracks”) that are built up from individually recorded audio segments (“layers”). Recorded material in the layers and tracks can be manipulated (playback rate, direction, blend, pan, level, start offset) post-recording for creative playback. Regen accepts stereo input and supports up to 4 stereo outputs. Regen allows Undo and Redo of recorded material and supports control via MIDI.

Refuzznik

Refuzznik is a free overdrive and saturation VST plugin developed by Transvaal Audio. Compatible OS(s): Windows.

Refuzznik is a distortion effect that applies a sinusoidal waveshaping function to its input signal(s). Sinusoidal distortion can be mixed with traditional shelving distortion. The relationship between input signal level and sinusoid frequency can be adjusted.

It has the following parameters:

ZeroX: ZeroX (short for “add zero crossings”) is an on/off parameter that affects the shape of the sinusoid function. If ZeroX = “No”, the sinusoid will map each input value to a value with the same sign (positive to positive, negative to negative). If ZeroX = “Yes”, the sinusoid may map a positive value to a negative one and vice versa.

InGain: This parameter determines how much Refuzznik amplifies the input signal before applying the distortion function. An increase in amplification results in louder and/or more distorted sound.

FuncMix: The FuncMix parameter is used to set the mix of sinusoidal and shelving distortion. At FuncMix = 0%, only shelving distortion is used. At FuncMix = 100%, only sinusoidal distortion is used.

AmpMin: This parameter is used to set the minimum amplitude of the sinusoidal function. When the signal level of the input is zero, the amplitude of the sinusoid is equal to AmpMin. The sinusoid amplitude increases with the input signal level and will approach the maximum “normal” VST signal level (which is 1) when the input level exceeds that maximum.

FreqMin: This parameter is used to set the minimum frequency of the sinusoidal function. When the signal level of the input is zero, the frequency of the sinusoid is equal to FreqMin. An increase in frequency usually results in harsher, noisier sinusoidal distortion. NOTE: Sinusoid frequencies are specified as the number of periods/cycles the sinusoid will go through when the input signal level increases linearly from the minimum value (-1) to the maximum value (1).

FreqDif: The FreqDif parameter determines how much the frequency of the sinusoidal function will change when the input signal level goes from zero to the VST maximum. If FreqDif > 0, the frequency will increase with the input level; if FreqDif < 0, the frequency will decrease.

REFLEX free

REFLEX free is a free delay and echo VST plugin developed by stw-audio. Compatible OS(s): Windows.

REFLEX free is an “Ambience Generator” that is capable of generating huge spaces, short rooms, or chorus-like modulations through a cascade of regenerating delays. Its sound is a mixture of straight stereo delays followed by a dense cloud of reflections. It achieves a huge and spacey wideness with a decent amount of the two modulation sources.

Features:

Short reflections up to endless reverberation.

Delay/Reverb Modulation.

Two modulation shapes.

Lean GUI.

Low on CPU.
