Orilriver

OrilRiver by Denis Tihanov

OrilRiver is a free algorithmic stereo reverb that can rival the quality of commercial reverbs. With this plugin it is possible to simulate the reverberation of a small room and great hall. It has an intuitive interface thanks to which the user can quickly adjust the desired reverb sound.

Parameter functions:

Dry button: turns on/off the dry signal. This parameter allows hearing only the wet signal for more own detailed setup. Also it allows using the OrilRiver like a send FX.

Dry slider: controls output level of dry signal.

Pre delay: determines the amount of time before the reverb begins up to 200.0 milliseconds.

Width: determinates the amount of the stereo width of the wet signal up to 100%.

E.R Variation: this parameter includes 12 variants of early reflections’ emulations. The block of early reflection consists of ten stereo delay lines (ten per channel). Each E.R. variation has a different duration and a different level of the delay lines. These variations were not taken from real premises and only make an imitation of them. For more convenient choice variations, the user can turn off the reverb tail (see Reverb button) and to hear only Early Reflections.

Reverb Variation: this parameter includes 5 variation of reverb tail. Each variation has a different density of the delays networks and has different resonant frequencies.
When processing a signal whose spectrum is close to noise (for example drum section, snare, hats), unpleasant resonances may appear. User can change the variation to eliminate resonances.
Variation1, Variation5, is suitable for emulation of small space.
Variation2, Variation4, is suitable for the medium-sized space emulation.
Variation3 for very large space.

Decay time: this parameter sets decay time of the reverb tail from 0.2 to 20.0 seconds.

Room size: sets the size of the selected early reflection variation and reverb variation.

Diffusion: sets the reverb tail density. Higher values lead to more diffusion and a smoother sound, lower values lead to a cleaner sound of the reverb tail.

H. damp.: controls the knee of where the high frequency damping begins from 4000.0 to 22020.0 Hz.

Damp. int.: controls the intensity of the high frequency damping.
When the value of the controller is set to 0.0 then damping of high frequencies in the reverb tail does not occur.

Mod. speed: controls the speed modulation of the reverb tail up to 20.0 Hz. It uses sinus oscillator.

Mod. depth: sets the depth of the modulation of the reverb tail.

Low Freq. shelf: controls the knee of the wet signal low equalization from 20.0 to 1000.0 Hz.

Low Gain: Simple gain control of the low shelving EQ from -24 to +12 dB. (When equal to –24.0, the filter becomes a High Pass Filter.)

Peak Freq.: controls the peak frequency equalization of the wet signal from 30.0 to 22000.0 Hz.

Peak Gain: simple gain control of the peak equalization from -24 to +12 dB.

High Freq. shelf: controls the knee of the wet signal high equalization from 1000.0 to 22000.0 Hz.

High Gain: simple gain control of the high shelving equalization from -24 to +12 dB. (When equal to –24.0, the filter becomes a Low Pass Filter.)

E.R. button: turns on /off the early reflections signal. This parameter allows hearing a signal processing early reflections.

E.R. slider: controls output level of early reflections from -∞ to 0.0 dB.

Reverb button: turns on /off the reverb tail signal. The parameter allows hearing a signal processing without the reverb tail.

Reverb slider: controls output level of reverb tail from -∞ to 0.0 dB.

Wet button: turns on/off the wet signal. Use this button for hearing difference of the dry signal and signal processing.

WET slider: controls output level of wet signal (early reflections + reverb tail) from -∞ to 0.0 dB.

Switching presets:
OrilRiver has a small number of factory presets, which will help the user to quickly adjust the desired sound.


Button that has a lock image is designed to lock the Dry/Wet controllers when switching presets.

Switching the GUI:


To switch the interface, it is necessary to click the left mouse button on the area located above the section of the equalizer.

Features:

  • 12 variations of the early reflections.
  • 5 variations of the reverb tail.
  • 3-band equalizer for the wet signal, which helps to create different shades of the virtual space.
  • Internal signal processing: 64-bit floating point.
  • Sample Rate: from 44100 to 192000 Hz.
  • Two graphical interfaces.
