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).

Correlometer

Correlometer free correlation-meter by Voxengo

Correlometer is a free correlation meter VST, VST3, Audio Unit, AAX plugin developed by Voxengo. Compatible OS(s): Windows 64b, macOS.

Correlometer is an analog-style stereo multi-band correlation meter plug-in based on the correlation meter found in the PHA-979 phase-alignment plugin.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

Correlometer features:

  • 4 to 64 band correlation meter.
  • Adjustable band quality factor.
  • Adjustable averaging time.
  • Side-chain input.
  • Resizable user interface.
  • All sample rates support.
  • Zero processing latency.
  • User interface color schemes.
  • Retina and HighDPI support.

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.

CopyShop

CopyShop free glitch by Shuriken

CopyShop is a free glitch VST plugin developed by Shuriken. Compatible OS(s): Windows, macOS.

CopyShop2 is a buffer chopping / FSU effect plug-in – it chops up the audio buffers and plays them back; you can choose the length of the piece of audio played back and when to apply it. CopyShop2 has a pitch controller as well, that does not change the length of the buffer.

Cooly

Cooly free software-synthesizer by PQN Audio

Cooly is a free software synthesizer developed by PQN Audio. Available format(s): VST for Windows.

Cooly combines a classic analog style oscillator with a SoundFont oscillator to produce cool pads and more.

Features:

  • Osc1 has 7 waveforms (sin, saw, ramp, triangle, pulse, white noise et pink noise) and is connected to a 4-pole resonant low-pass filter. The cutoff frequency can be modulated by an LFO.
  • The filter has a dedicated envelope (ADSR).
  • Osc2 has 6 waveforms (attack, brass, organ, string, analog, perc).
  • The 2 oscillators share the same amplitude envelope (ADSR) but you can adjust the volume of each oscillator separately.
