2. 1. Description
Echo Chamber is a stereo Reverb and Delay plug-in effect, used to create psychoacoustic models to
simulate sounds reflecting from surfaces in a room or space. Optionally a delay can be added to yield a
spacious and open sound of a repeating, decaying echo to complete a sense of space and depth to a
'dry' input signal.
A highly tweakable, versatile, and inspiring solution for ambience effects, that produces a natural
sounding room reverberation and delay effect giving a true room perception, from small rooms to large
caverns as well as generates a doubling echo, slapback echo, ping-pong delay and analog tape delay.
Offers multiple controls for modifying one or both channels to produce a rich array of time-based
effects.
These VST and VST3 plug-ins are perfectly suited for any type of audio production when acoustic space
simulation is needed from recording to post production in 64 bit platforms. Small rooms have a high
percentage of early reflections (the first feedback from the closest objects) that can give more body to
tracks. It is also good with acoustic guitars and voices. Larger rooms presets are better with strings, or
wind instruments and synthesizer pads.
Features
 Reverb and delay algorithms that delivers a rich reverberation and echoes by providing a
spaciousness and depth to simulate the sound reflections from walls, floors and ceilings in an
acoustically reflective environment.
 Flexibility to control Left and Right channels separately in Reverb and Delay units as well as in
'dry' signal output.
 Reverb unit works as a Stereo enhancer and mono-to-stereo creator, to produce a wide stereo
image or stereoize a mono sound source. In Delay unit, improves the stereo image by adding
a slight delay to one of the channels.
 Delay Time manual or synced to host (Tempo Sync BPM).
 12 Reverb Presets: Predefined space types, giving a virtually infinite number of possible
shapes and sizes. These presets consist of some parameters to determine apparent room size,
reverberation time, distance from you to the performer, etc.
 4 Delay Presets: Doubling Echo, Slapback Echo, Ping-Pong Delay and Analog Tape Delay.

Note: In each predefined reverb or delay these parameters are preset with values precisely calculated by Syntheway
to create the sound field unique for the program. Each preset has a set of parameters that allow you to change the
characteristics of the acoustic environment to precisely create the effect you want and contribute to your personal
sound field, allowing you to essentially 'redesign' the spaces and echoes, provided to create custom-tailored listening
environments that ideally match your mood and music.
PARAMETERS:
- DRY Signal Output (Left and Right): It independently controls the left and right channels 'dry'
(unaffected) signals. Turn the knob clockwise to increase the dry signal or counterclockwise to
decrease it. Default:0. Input signal is fully processed according to the reverb / delay stereo
shaping wet assignments.
REVERB UNIT:
- WET Reverb Stereo Shaping (Left and Right): It independently controls the left and right
channels wet signals. Turn the knob clockwise to increase the wet signal or counterclockwise to
decrease it.
• SPACE Controls: Consist of size, width and depth knobs. These parameters determine the
nature of the space and its properties such as its abstract geometry and determine its
complexity.

4. • Size: This knob varies the apparent size of the simulated acoustic space by
controlling the density of the early reflections as well as the slope of the buildup. Turn
the knob clockwise to increase the size or counterclockwise to decrease the size.
• Width: This knob adjusts the stereo separation of the wet reverb signal. Turn the
knob clockwise to widen the stereo image or counterclockwise to reduce the stereo
effect.
• Depth: Adjusts the depth of the environment by controlling the apparent distance
from the listener to the input source. It Ranges 0 (near) to 10 (deepest). Turn the knob
clockwise to increase the depth or counterclockwise to decrease the depth.
• COLOR Control: Turning the control up, provides additional high-end presence in the effect.
• TONE Control: Changes the tone of the reverb by taking over high frequencies. At
times subtle, these changes can alter the timbre or quality of auditory sensations
produced by the tone of a sound of reverb, from dark to bright and everywhere in
between.
• Bright: A shimmering tone. Overbearing high frequencies. Treble emphasis
(Fully clockwise rotation).
• Warm: Well balanced, flat, neutral. Pleasantly spacious, with adequate
reverberation (Tuning around the center position of the knob).
• Dark: A tonal balance that tilts to tones of low (deep) frequency. Weak high
frequencies (Fully counterclockwise rotation).
• PRESENCE Combo Box: Makes subtle changes to the reverb character:
• Stage 1: Tone reverb is slightly attenuated. Provides a warmness tone.
• Stage 2: Tone reverb is slightly amplified. Something brighter in character.
DELAY UNIT
- WET Delay Stereo Shaping (Left and Right): It independently controls the left and right
channels wet signals. Turn the knob clockwise to increase the wet signal or counterclockwise to
decrease it.
• FEEDBACK (Left and Right Channels): Regeneration of delay. By increasing the amount of
signal sent back through (or fed back, or regenerated) the number of repeats is increased
Individually for left and right channels. Turn the knob clockwise to increase the rate or
counterclockwise to decrease the regeneration. Also feedback can be entered by typing in the
desired amount in the text box of each left or right channel.
• TIME (Left and Right Channels): Controls the delay time. The value can either be in
milliseconds or in bar divisions if the Tempo Sync (BPM) is switched ON.

5. • Manual Time (Left and Right Channels): This knob sets the delay time manually.
Controls the speed of the effect when not synchronized to host tempo. Improves the
stereo image by adding a slight delay to one of the channels. Time can be entered by
typing in the desired amount in the text box of each left or right channel in
milliseconds.
• Tempo Sync (BPM) ON/OFF:
- OFF (Default) makes no synchronisation. Time is set by the user by 'Manual
Time' knob.
- ON allows to sync the delay tempo to the host. Controls the speed of the
synchronized effect to the project tempo, including tempo changes. Also is
mapped to control the delay subdivisions for some tempo synced delay changes.
Switch options have programmed subdivision, it goes from 1/1 to 1/16 triplet.
• Bar Divisions (Combo Box. Left and right channels): Used with ‘Sync Time
(BPM)=ON’ makes the Delay time sync to the host BPM and allows specifying delay
times in musical note durations. Independently control the left and right channel
signals. Default 1/1 in both L/R channels.
• Range: 1/1, 1/2, 1/2D, 1/2T, 1/4, 1/4D, 1/4T, 1/8, 1/8D, 1/8T, 1/16, 1/16D,
1/16T. Improve the stereo image by adding a slight delay to one of the channels.
T = Triplet: Delay time equal to 2/3 of the duration of the selected vote value.
D = Dotted: Delay time equal to 3/2 of the duration of the selected note value.
• COLOR Control: Turning the control up, provides additional high-end presence in the delay
effect.
• TONE Control: Changes the tone of the delay by taking over high frequencies. At times
subtle, these changes can alter the timbre or quality of auditory sensations produced by the
tone of a sound of reverb, from dark to bright and everywhere in between.
• Bright: A shimmering tone. Overbearing high frequencies. Treble emphasis (Fully
clockwise rotation).
• Warm: Well balanced, flat, neutral. Pleasantly spacious, with adequate reverberation
(Tuning around the center position of the knob).
• Dark: A tonal balance that tilts to tones of low (deep) frequency. Weak high
frequencies (Fully counterclockwise rotation).
• PRESENCE Combo Box: Makes subtle changes to the delay character:
• Stage 1: Tone delay is slightly attenuated. Provides a warmness tone.
• Stage 2: Tone delay is slightly amplified. Something brighter in character.

6. * Note: Setting different delay time in left and right channels allow to create the 'Precedence effect', a
binaural psychoacoustic effect, when a sound is followed by another sound separated by a sufficiently
short time delay (below the listener's echo threshold). The Haas effect, also a psychoacoustic effect
(by Helmut Haas) is often equated with the underlying precedence effect. The precedence effect
appears if the subsequent wave fronts arrive between 10 ms and about 50 ms later than the first wave
front. For speech the precedence effect disappears for delays above 50 ms, but for music the
precedence effect can also appear for delays of some 100 ms. It causes a listener to perceive a space
and direction of a sound when there is a slight delay between stereo channels.
Reverb and Delay Presets Description
• 1. Room Reverb: This reverb effect simulates the acoustics of a small room with a low
ceiling and a quick decay. The sound is very close and intimate.
• 2. Hall Reverb: Bright classical concert hall with strong room impression. This is a dense
hall reverb In this program, the center will appear to be deep behind the main speakers,
creating an expansive large hall ambience. Orchestra and opera music are suited for this
sound field.
• 3. Chamber Reverb: Ambient natural sound of a small chamber. A smaller physical space
than a hall that results in more clarity yet still provides a blend of harmonic content and
dispersion of sound.
• 4. Plate Reverb: Straight and bright reverberation plate sound. Reverb emulation that
utilizes transducers that send and receive a signal through a sheet of metal.
• 5. Spring Reverb: Natural, metallic spring reverb. Similar in design to the plate,
however, it uses a metal spring instead of a sheet.
• 6. Ambience Reverb: Large enclosure ambience sound. This effect adds a perfect match
for pure synthetic sounds.
• 7. Church Reverb: Smooth and clear big church reverb. This program recreates the
acoustic environment of a big church with a high pointed dome and columns along the sides.
This interior produces very long reverberations.
• 8. Arena Reverb: This reverb effect simulates the acoustics of a large enclosure such as a
sports arena.
• 9. Opera Reverb: Typical sound of a classical bright opera house.
• 10. Theater Reverb: Natural sounding audience hall of a theater.
• 11. Cathedral Reverb: Big cathedral with characteristic echoes.
• 12. Cave Reverb: Stereo Echo Delay and Reverb. This effect simulates the reverberations
of a cave.
• 13. Doubling Echo: Is produced by adding short-range delay to a recorded sound. Delays
of 30 to 50 milliseconds are the most common; longer delay times become slapback echo.
Mixing the original and delayed sounds creates an effect similar to doubletracking and can
help greatly thicken up a vocal recording. It’s also often used for recording guitar with a
stereo effect.
• 14. Slapback Echo: Uses a longer delay time (75 to 250 milliseconds), with little or no
feedback, often used on electric guitar, but can also be applied to drums or vocals. Most
often heard in rockabilly and country.

7. • 15. Ping-Pong Delay: This type of delay 'pings' audio back and forth between the left
and right channels, creating a wide stereo rhythmic effect. Useful to create syncopated
rhythm lines that bounce from left to right.
• 16. Analog/Tape Delay: Is inspired by classic analog delays using reel-to-reel tape
loops, earliest delay types in the budding Rock and Roll era of the 1950s.

 Place the following files / folders into your plugins folder:
 Echo Chamber Reverb and Delay VST folder in your VST2 Plugins x64 folder.
 Echo Chamber Reverb and Delay VST3 folder in your VST3 Plugins x64 folder.
To uninstall simply remove:
 Echo Chamber Reverb and Delay VST folder from VST2 x64 Plugins.
 Echo Chamber Reverb and Delay VST3 folder of your VST3 x64 Plugins folder.

10.  VST3 Presets (.vstpreset)
The contains of VST3 Presets folder should be placed manually.
 If VST3 Presets folder exists in Documents, just place the Syntheway folder inside the
following path:
C:Users*username*DocumentsVST3 Presets
 If VST3 Presets folder doesn't exists in Documents, just drag and drop the complete
VST3 Presets folder.
After that, the complete path will look like the following:
C:Users*username*DocumentsVST3 PresetsSynthewayEcho Chamber Reverb and Delay
with the *.vstpreset inside. FL Studio, Cubase, Nuendo, REAPER and Bitwig Studio will
display automatically on preset manager.
 Alternatively .vstpreset can be loaded from Echo Chamber Reverb and Delay VST3
main folder (currently included) for PreSonus Studio One and Cakewalk by BandLab via
preset manager option.
