Reverb Machines: Reflections
The Reflections machine is a psycho-acoustically accurate small-space reverb that allows you to move your amp anywhere in
the room. The Reflections algorithm precisely calculates 250 reflections based on the source position within the chosen room
shape. The psycho-acoustic modifiers adjust for human auditory perception to create unparalleled ambient-space realism to
dry instrument or vocal tracks.
PARAMETERS:
F | | B
+ | | -
L | | R
Location Y: Positions the amplifier towards the front (F) or back (B) of the room. The reflections
are re-calculated accordingly with the movement of the amp. When the amp is in the
front of the room (closest to you), the dry signal will dominate over the reflections,
whereas moving the amp to the back will result in the reflections arriving at times and
amplitudes similar to the direct sound, thus appearing more reverberant overall.
Low End: Affects the low frequency decay profile. As you turn it up, more low frequencies
reverberate creating the impression of longer decay times and a room that is sparsely
furnished.
Location X: Positions the amplifier towards the left (L) or right (R) of the room. The reflections are
re-calculated accordingly with the movement of the amp, and the dry signal is panned
through the stereo analog buffers to give proper imaging.
Shape: Selects the shape of the room that is producing the reflections. The Square shape is
(you guessed it) square, while the Rectangle shape is short and wide with Golden Ratio
dimensions (1.618:1), and the Oblong is long and narrow with Golden Ratio dimensions
(1:1.618).
TIPS & TRICKS:
The Decay knob adjusts the size of the room from 100 sq ft (10’x10 square, or 8’x13’ rectangle and oblong)
to 1000 sq ft (31’x31’ square, or 24’x39’ rectangle and oblong). As the room size increases, the decay
increases accordingly.
Set Mix at 12:00 and Pre-Delay to 0 (minimum) for a natural room response.
Darker Tone settings would come about from carpeting, drapes and other absorptive elements on the
reflecting surfaces. Brighter Tone settings create the sound of stone or tiled walls, with fewer absorbing
materials in the room.
Reduce the Low End to give a more natural room or studio environment with furnishing/couches etc.
Increase Low End for more of an ‘empty space’ reverberation.
The Mod control modulates the Pre-Delay time to create a randomized chorus effect against the dry
signal.
