Reversinator

Reversinator is a free glitch VST plugin developed by ndc Plugs. Compatible OS(s): Windows, macOS.

Reversinator, a “simplistic realtime audio-reversing plugin”.

The input audio is read into a 88200-sample buffer, which has two read pointers (going in the opposite direction of the write pointer), half the buffer apart. The sound from each pointer is mixed according to a raised cosine type envelope, to ensure the volume is constant, and that you never hear the discontinuity between the previous data and the new data being written in.

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.

Refractor is a free software synthesizer for Reaktor, developed by Noizefield Instruments. Available format(s): for Windows, macOS.

REFRACTOR is a synthesizer for Native Instruments Reaktor, based on Karplus Strong synthesis. Instead of using noise as the impulse this synth does use sample-wavetables. Therefore the results are much more experimental, unforeseeable and multifarious. Several delay lines, a multimode filter and special tweaks make this synth unique.

Works with Native Instruments Reaktor 5.9.4 and above.

ReFine

ReFine is a free enhancer and exciter VST, VST3, Audio Unit plugin developed by lkjb. Compatible OS(s): Windows 64b, macOS.

ReFine is a plugin that allows to add a final polishing to your tracks, busses and masters. It extracts psycho-acoustic parameters from the source and thus allows to add warmth, space and punch to your mixes. This is done level dependent and rather subtle; you probably won’t be able to create heavy distortion effects with this plugin.

Version 1.1.0 won’t be compatible with earlier versions but 1.1.0 can be installed alongside previous versions if one of the plugin is renamed. Since the amount of controls isn’t too high migrating shouldn’t be a problem.

The plugin is now open source.

The manual is available here.

Changelog:

1.2.0: JUCE update.

1.1.0: moved plugin to JUCE, added AU format, added x2 toggle.

1.0.6: fixed crash in mono instances.

1.0.5: fixed CPU issue in Cubase during silence.

1.0.3: added support for older VST hosts on Windows, OS X 10.6 support.

1.0.2: fixed denormalisation bug.

1.0.1: fixed high CPU bug (appeared when silence was put in after a signal).
