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.

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.

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.
    • 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.
    • 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.
