CrunchDude

CrunchDude free overdrive | saturation by Heeb

CrunchDude is a free overdrive and saturation VST plugin developed by Heeb. Compatible OS(s): Windows.

CrunchDude is a simple guitar amplifier emulation. As the name implies, its strength lies not only in clean or over-the-top lead sounds, but especially in the crunch sounds it can produce.

Features:

  • The Input section. No distortion takes place here yet, only amplification and equalization plus a Low Cut control (which determines the cut-off frequency of the 6 dB/octave filter).
  • Two Pre-amp sections. These are switched in series, and are completely equivalent. You can switch them on and off. They have a 3-band equalizer with adjustable cut-off frequencies, and a Drive dial that determines the gain and the resulting distortion. The equalizer is “passive”, which means that when Low, Mid, and High are in maximum position, no alteration of the sound takes place (flat frequency response, 0 dB gain).
  • The Output Stage section. Again, you have the same type of 3-band equalizer at your disposal, an Output level dial, and an extra Low Cut.
  • The Cabinets section. There are two almost identical sections in parallel here, which you can balance with the Mix dial. You can switch this section off. The sound of both sections is determined by their Prox (proximity) and Fdb (feedback) dials.

CromFX

CromFX free multi-fx | chorus | delay | phaser by WOK

CromFX is a free multi fx and chorus and delay and phaser VST plugin developed by WOK. Compatible OS(s): Windows.

CromFX is a vintage-style effect plug-in with different chorus, phaser and delay models.

CromFX features 4 chorus variations, modelled after vintage circuits, 3 phaser types and the choice between 2 delays with host sync, of which one is simulating a tape delay.

The multi-chorus unit delivers lush and deep modulation sounds. The deep phaser effect and the delay can be added to accomplish the vintage sound.

The reproduction of the sonic instabilities of old hardware in this plugin transforms a simple sawtooth synth into a swirling string ensemble or a wide analog pad. But the comprehensive controls make it suitable for a wide range of signals from bass or drums to even vocals.

  • Band Pass attenuates both above and below the cutoff frequency, for a “thin” or “nasal” sound.
  • High Pass removes low frequency signals.
  • Notch removes just a small band of frequencies from the signal.
  • Peak boosts a small band of frequencies in your audio.

Couture

Couture free saturation by Auburn Sounds

Couture is a free saturation VST, VST3, Audio Unit, AAX, LV2 plugin developed by Auburn Sounds. Compatible OS(s): Windows 64b, macOS.

Couture gives you control over your dynamics, and particularly attacks.

Raw Efficiency. Increase or decrease dynamics. Get a usable result, now.

Fully Volume-independent. Keep the freedom to change input gain when needed. Including the Saturation stage.

Laser-sharp. Couture’s 2-bands, half-spectral, RMS, program-dependent detector finds each and every transient. No internal thresholds.

Couture is very versatile:

  • Make individual drum tracks a lot more dynamic and punchy
  • Remove the “click” out of a kick drum sample
  • Make a whole bus more or less dynamic in a single click
  • Give glue to a mix with light compression and saturation.
  • Use a subtle saturation that preserve dynamics.
  • Deess the very start of notes for vocals.

Courvoisier

Courvoisier free compressor by Weldroid

Courvoisier is a free compressor VST plugin developed by Weldroid. Compatible OS(s): Windows.

Courvoisier is a single-band universal dynamics processor with adaptive attack and release algorithms optimized for complex program material (mixes and submixes). Courvoisier uses free-form curves drawn over the histogram of incoming audio material (as opposed to traditional ratio and threshold parameters) to determine the transfer function of the processing.

Features:

  • Histogram representation (sliding-window statistics) of incoming program material and gain change.
  • Free-form dynamics processing defined by curves.
  • All performance-critical code optimized in assembly (utilizing SSE2 flow instructions).
  • Very low harmonic distortion (THD during normal operation is below -105 dB FS).
  • Two different program dependent attack algorithms.
  • Two release algorithms (program dependent and user defined).
  • Side chain filtering (low and high pass filters).
  • M/S operation with optional side channel transfer function.
  • Stereo operation with adjustable stereo link.
  • Dry mix option for parallel processing.
  • Peak, RMS and Hybrid level detection options.
  • Look-ahead processing for minimizing distortion with extremely fast attack settings.
  • Complex mode (oversampling with a twist).

Corkscrew

Corkscrew free pitch-shifter | time-stretcher by Anarchy Sound Software

Corkscrew is a free pitch shifter and time stretcher VST, Audio Unit plugin developed by Anarchy Sound Software. Compatible OS(s): Windows, macOS.

Mixes together multiple pitch-shifts of the input signal, increasing or decreasing their pitches in parallel, and fading them in/out at the extremes of their range.

This creates the illusion of a sound that seems to continually rise or fall, but doesn’t actually change in average pitch.
