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.

Ranger LE

Ranger LE is a free filter and saturation VST plugin developed by Ourafilmes. Compatible OS(s): Windows.

Ranger LE is a smaller version of Ranger and is a very simple effect that allows you to remove unwanted frequencies and saturate the resulting signal.

It features one low cut filter and one high cut filter (12 or 24 dB per octave) and a final gain knob. There’s also a master bypass switch.

This effect has full automation.

This is a free plugin but, to download, you must be a fan of the Ourafilmes Facebook page as it is included in the Ourafilmes Facebook Free Pack.

Radio Junk

Radio Junk is a free distortion and filter VST plugin developed by Cupwise FX. Compatible OS(s): Windows.

It’s a small but unique suite of effects made from 2 junky old radios, one solid-state (from the 70’s) and the other a tube radio (from the 50’s). The radios were ‘sampled’ using technology similar but superior to the common convolution impulses out there. It’s called Nebula, and it can capture the sound of what’s being sampled at different dynamic levels, and it can also capture some of the distortion, unlike standard convolution.

These effects use a variant of the Nebula tech called ‘Acqua’, which just means that these are stand-alone effects, and you don’t need Nebula to load them (it’s built in, basically). The radios were sampled in extreme ways to get some nasty lo-fi effects. Since these were made with the Nebula technology, they will sound different from other plug-ins out there. You should grab them and give them a try! They’re free!

qWarpFilter

qWarpFilter is a free filter VST plugin developed by Mutagene. Compatible OS(s): Windows.

qWarpFilter allows the user to perform a warped LP analysis of the input signal for each of four independent filter banks, where after the user can warp between all four filters using the XY touchpad control or use the ‘filter warp’ slider to change the warping in the filtering stage.

The results tend towards bellish sounds or weird sleeping sounds reminiscent of the EMU Morpheus’ filters.

QRange

QRange is a free equalizer VST, VST3, Audio Unit plugin developed by lkjb. Compatible OS(s): Windows 64b, macOS.

lkjb QRange is a IIR linear phase EQ with the following features:

12 bands (sortable by frequency).

Each band can be used as peak, shelf and cut filter.

Cut filters are available with 12, 24 and 48 dB/oct steepness.

Stereo/Left/Right/Mid/Side routing per band.

Global gain for loudness adjustments.

Resizable user interface.

Gain Match (new in version 1.0.1).

Latency-free minimal phase mode (new in version 1.1.0).

The analyser can be set to analyse pre-EQ and post-EQ signal applying the same routings that are available per band. It is possible to adjust the analyser minimum/maximum magnitude by dragging the scale on the right (visible only if the analyser is active).

A menu which is available via the gearwheel provides:

Adjusting Analyser Range.

Adjusting frequency display magnitude.

Adjusting the plugin latency.

Setting a default EQ state and/or user interface size for new instances.

QRange uses IPlug-Youlean as plugin framework. From JUCE juce_core and juce_audio_basics modules are used.
