F8-V2

F8-V2 is a free multi fx and filter and ring modulator and reverb and gate and lfo and echo and pitch shifter 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.

EMONIZER

EMONIZER is a free pitch shifter VST plugin developed by WOK. Compatible OS(s): Windows.

EMONIZER is the third one-trick pony by WOK.

It’s a micro pitch shifter, that creates two slightly detuned copies of the original audio, which can be spread in the stereo field.

It’s a tool to fill vocal tracks, but also works great on guitar and other sounds.

EMONIZER is available for free as a 32-bit VST plugin for Windows.

Duet

Duet is a free harmonizer VST plugin developed by Martin Eastwood Audio. Compatible OS(s): Windows.

Duet is a double-tracking/harmonizer effect developed to enhance vocals and instruments by thickening the sound and adding a rich glossy sheen to the audio material.

Duet works by independently pitch-shifting the left and right inputs allowing pitch to be manipulated in real-time, while still maintaining the time duration of the audio. By also delaying the re-pitched audio and altering its pan position, Duet can accurately create the illusion of multiple voices and add a luscious texture to your music.

Duet can also be used to create a silky chorus effect through modulation of the pitch-shift amount and to add movement and texture to synths.

Duet is available exclusively on Computer Music Magazine’s cover DVD each month.

dTUNE

dTUNE is a free pitch shifter and time stretcher VST plugin developed by WOK. Compatible OS(s): Windows.

dTUNE is a voice doubling/detuning effect plug-in. It generates two detuned signals of the input, making thin synth sounds more fat or fill up vocals or drums.

DtBlkFx

DtBlkFx is a free multi fx and eq and filter and vocoder and pitch shifter and delay and distortion and flanger and phaser VST plugin developed by Darrell Tam. Compatible OS(s): Windows, macOS.

DtBlkFx is a Fast-Fourier-Transform (FFT) spectral processing plug-in.

Features:

Precision parametric equalizing with sharp-roll off:

Set the frequencies so accurately that you can adjust individual harmonics of a sound.

Frequency resolutions of up to 0.7 Hz.

Harmonic based (or comb) filtering:

Set a fundamental frequency and adjust the level of it and its harmonics – you can even remove the pitched component of a voice.

Active harmonic tracking – let DtBlkFx automatically track a sound and adjust the level of its harmonics.

Various types of noise control:

Change the “contrast” between loud and soft frequency components.

Adjust only those frequencies below or above a particular threshold.

Clip frequencies above a particular threshold.

Sound smearing (phase randomizing).

Frequency shifting:

Harmonic shifting by a fixed number of notes.

Non-harmonic shifting by a fixed frequency.

Active harmonic repitch – the content of your sound is monitored and re-pitched to a destination note.

Vocoding:

Standard (frequency enveloping) – make your trumpet rap, string section sing or synthesizer talk.

Harmonic based – harmonics in one channel are power-matched to those in the other (or some predefined waveforms) for a new vocoding sound.

Frequency masking:

A harmonic or threshold mask may be set for any effect (apart from vocoding) – for example only shift frequencies that are below the threshold.

Realtime spectrogram (waterfall) display of input and output sounds:

See what frequency components are in your sound and exactly what you’ve done.

Use your mouse to see the note & frequency under the pointer.

You can select up to 4 of the above effects to be run in series – combining the effects in this way allows you to make completely new and surprising sounds.

DtBlkFx is freely distributable and is covered by the terms of the GNU licensing agreement. Source code is included.
