Reverb

PSP PianoVerb

PSP PianoVerb is a free reverb VST, Audio Unit, RTAS, AAX plugin developed by PSPaudioware. Compatible OS(s): Windows 64b, macOS.

PSP PianoVerb reproduces a special kind of reverberation originally provided by piano strings. It generates reverberation using twelve string operators with adjustable damping and decay time. Each of them is tuned to a particular note starting from A(55Hz) to a G#(103.8Hz).

The PSP PianoVerb string system can be transposed in the range of +-24 semitones, tuned within a range of +-100 cents and be detuned as well. Transposing to lower octaves produces a bigger and less resonant sound similar to traditional reverbs, while in turn transposing to higher octaves produces a very bright harp-like effect.

Protoverb

Protoverb is a free reverb VST, Audio Unit, AAX plugin developed by u-he. Compatible OS(s): Windows, macOS.

Protoverb is an experimental reverb based on the idea of a “room simulator”.

This first version of Protoverb is released as a free “research-ware” plug-in, created to discover more about reverbs.

Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a rooms walls. Protoverb does the opposite. It builds up as many room resonances as possible, modeling the body of air in the room. It therefore does not need to modulate or colour the signal. The result is a very natural sounding reverberation with some interesting features: Long standing frequencies resonate louder, as if the air takes some time to get excited. Multiple instruments don’t mash into a diffuse mudd, they stay distinct. If you play a short melody, the room seems to repeat a ghost echo of that melody. Those properties are indeed found in churches and large halls, but they’re rarely found in conventional algorithmic reverbs.

Protoverb has limited controls, with most parameters hidden from user control. There are 2 randomise buttons that modify these parameters to encourage user experimentation.

Poor Plate

Poor Plate is a free reverb VST, Audio Unit plugin developed by vacuumsound. Compatible OS(s): Windows, macOS.

Poor Plate is a stereo plate reverb plug-in which emulates a plate reverb algorithm as it was used in the very first digital reverb machines.

Controls:

Dry Level: the level of the original signal, off – 0db.

Wet Level: the level of the reverb signal, off – 0db.

Pre Delay: pre-delay in milliseconds, 0-120.

Decay: decay rate, i.e. how long the reverb tail gets,0.0 – 0.9.

Decay Diffusion: amount of diffusion of the reverb tail.

Input Diffusion: amount of diffusion of the input signal.

Bandwidth: input signal bandwidth, in Hz.

Treble Damping: damping of treble in reverb tail, in Hz.

Pedals

Pedals is a free multi fx and overdrive and saturation and amp simulator and delay and echo and flanger and phaser and pitch shifter and reverb and eq and filter VST plugin developed by ToneBytes. Compatible OS(s): Windows.

Pedals is a VST effect plug-in designed for processing electric guitar and bass. It is also possible to process other audio sources for a variety of artistic techniques.

The Pedals GUI simulates real devices for sound processing: guitar pedals, amplifiers, speakers, etc. There are a total of 20 models of pedals, 2 amps, 7 speakers models and 3 rack units. These devices are not a copy of the real-life models, each with their own sound, but their working principles are identical.

The user can select a combination of effects and can even create extra mood by choosing floor material under the pedals: house parquet, metal garage floor or studio carpet.

There is a built-in preset manager to save the settings and access them or share them with other users. VST automation and full MIDI Learning are supported.
