GTune

GTune free tuner by GVST

GTune is a free tuner VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GTune is a chromatic instrument tuner which operates much like its hardware counterparts. It will automatically detect the pitch of a note being played, and display the Western scale note that it is closest to.

The main part of the display mimics a typical electronic tuner. When a pitch is detected, the nearest note is displayed along with an LED-style indication of flatness/sharpness.

There is also a text display providing more accuracy, should it be needed. It gives the detected frequency in Hertz and its position in the Western scale. The latter is shown as a note-name and an offset in cents. For example, “E -13” indicates that the detected pitch is 13 cents below E.

GSnap

GSnap free pitch-corrector by GVST

GSnap is a free pitch corrector VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GSnap is an auto-tune effect. It can be used subtly to correct the pitch of a vocal, or, with more extreme settings, to create a robot-voice effect.

For GSnap to work effectively, the input signal should be monophonic, at a good level and reasonably noise-free. For example, a clean, mono vocal recording, without excessive noise or reverb. Effect plug-ins should be placed after GSnap in the signal chain.

GSnap starts off by detecting the pitch of the incoming audio. The Min Freq and Max Freq parameters help the pitch-detector by narrowing the range of frequencies it needs to consider. Also, the Gate parameter should be set so that the pitch-detector ignores background noise during “silent” passages.

The Speed parameter sets the number of wave repetitions required for positive pitch-detection. Lower values for Speed will allow faster pitch-detection, but will increase the chance of false detection. The default value should be fine in most cases.

Once a pitch has been determined, GSnap applies the specified pitch-correction. There are two modes of pitch correction: fixed scale and MIDI. Fixed scale correction has a fixed set of snap-notes, while MIDI correction is controlled in real time by MIDI data.

The Threshold parameter sets the largest pitch-shift that will be applied to the input. It defines a region around each snap-note that will be corrected to that note. The GUI shows the snap-notes and regions in effect at any time.

The pitch-detection and correction can be made to use a different reference frequency using the Calibrate parameter. This sets the frequency of A above middle C.

Additionally, GSnap will respond to pitch-bend and modulation MIDI messages to apply pitch-bend and vibrato. The Pitch Bend, Vibrato and Vib Speed parameters control these effects.

GSinth2

GSinth2 free software-synthesizer by GVST

GSinth2 is a free software synthesizer developed by GVST. Available format(s): VST for Windows 64b, macOS, Linux.

GSinth2 is essentially the same as GSinth, but with a few extra features. Most notably, GSinth2 offers new oscillator types: triangle, square and saw-tooth.

GSinth is a monophonic synth with three sine oscillators. It also features an LFO for controlling the output level.

The first oscillator will play at the frequency of the MIDI note pressed. The remaining two oscillators can be set to play at a multiple of this frequency. You can also de-tune each oscillator.

For each oscillator, you can set attack, release and portamento times. The portamento time is the time taken to “slide” from one note to the next.

The PortaRst parameter sets the amount of time before resetting portamento. After that time, a new note will not “slide” from the previous note. This is useful to prevent the first note of a piece from sliding from whichever note was played last.

The Random button randomizes all of the parameters. This can often give inharmonic sounding results because of oscillator de-tuning. Holding shift while clicking on Random produces better-behaved presets.

The AutoLevel button will set the MainLvl parameter so that the peak output level is around -3dBFS.

GRevDly

GRevDly free delay | echo by GVST

GRevDly is a free delay and echo VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GRevDly is a delay effect that plays the delayed signal in reverse.

Reversed chunks are cross-faded to eliminate clicks. The Overlap parameter controls the amount each chunk overlaps with the next.

GNormal

GNormal free other-utility by GVST

GNormal is a free audio and studio utility VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GNormal tries to remedy denormal problems by introducing extremely low-level noise to the signal path. (If you don’t know what that means, then you probably don’t need it).

Some CPUs employ techniques to extend the accuracy of floating-point calculations for very small numbers. These small numbers are called denormals.

Unfortunately, calculations involving denormals can be very slow. This can drastically affect audio DSP performance. In most cases, these numbers are too small to be of any interest anyway.

Adding noise to the signal path can sometimes prevent denormals from getting into subsequent calculations. Obviously, the noise-level used is so low that you cannot hear it.

The simplest way to configure GNormal is to place it before a suspect plug-in and set the Level parameter to maximum. Try each setting of the Type parameter to see if the problem goes away. When you have found a suitable noise-type, you can try lowering the Level.

GMulti

GMulti free compressor by GVST

GMulti is a free compressor VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GMulti is a three-band compressor and stereo enhancer.

First, the signal is split at user-defined frequencies into three bands. Each of these bands can then be compressed independently and have its stereo width altered before being mixed back together.

The compression of each band is specified in the usual manner with threshold, ratio, attack and release controls.

The GUI contains gain-reduction meters for each band, which have a resolution of 1dB per bar. There is also a before/after waveform display, which can display any of the three bands. The waveform display features a zoom control, which allows the display to be scaled for optimum viewing.

The stereo enhancement works by amplifying or diminishing the stereo information in each band. If you set a Width parameter to 0% then the associated band is collapsed to mono, which is often desirable for the bass band.

The Mix parameter allows the pre-compression signal to be mixed back into the output signal. You can use this to restore some of the dynamics of the original signal.

GMax

GMax free compressor by GVST

GMax is a free compressor VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GMax is a maximizing limiter. It is designed to boost the level of the signal without letting the peaks exceed a given maximum.

The Gain parameter sets the desired boost in volume. The signal will be boosted by this amount before going into the limiter.

The limiter reduces the signal level as necessary to keep it below that specified by the Ceiling parameter. The Release parameter sets the time taken for the limiter to recover after turning the volume down.

A meter is displayed on the GUI showing the gain reduction applied by the limiter. The resolution of this meter is 1dB per bar.

GLow

GLow free filter by GVST

GLow is a free filter VST plugin developed by GVST. Compatible OS(s): Windows 64b, macOS, Linux.

GLow is a resonant low-pass filter. It is used to remove all frequencies from a signal above a given cut-off point.

Increasing the resonance of the filter causes the frequencies around the cut-off to be boosted.

Resonance can create large peaks in the output. Because of this, the GUI features a peak display showing the maximum peak output level. The peak display is reset by clicking on it.
