MolecularBytes ‘Atomic Reverb’: A Sonically Evolved Reverb Plugin running under Innovative Room Algorithms with a Variety of Controls 


Atomic Reverb provides all possibilities to create stunning dense, smooth and natural reverb with a high degree of customization  




Atomic Reverb is a reverb plugin based on innovative room algorithms running under common interfaces such as VST 2, VST 3, and AudioUnits. Atomic Reverb supports a set of over 170 different predefined ‘early-reflection signatures’ extracted from real room impulse-responses and provides various algorithms for ‘late-reverb’ (reverb tail), ‘wall-absorption effects’, ‘complex modulations’, and ‘gated tail length’. This highly configurable processing for both ‘early-reflection’ and ‘late-reverb’ provides a maximum flexibility throughout the entire spectrum enhancing the sonic range to produce sounds from subtle voice reverbs to full and dense broad spatial reverbs. Atomic Reverb did not adopt static models of reverb effects such as convolution or impulse-response but simulated moving airflow from its complex modulations in reality adding deep, breezy, and individual reverb-tails for every instance. Atomic Reverb is equipped with a variety of controls such as ‘room-size’, ‘room-width’, ‘stereo-position’, ‘different damping parameters’, and a ‘5-channel EQ with spectrum-analyzer’ for users to design individual sound colors. To keep the highest quality of reverb sounds, Atomic Reverb uses an internal 64-bit signal processing with optional 2x oversampling and high degree sample interpolation. Atomic Reverb comes with a huge set of 240 predefined factory presets which are intuitively modifiable to support the maximum productivity for designing breathtaking sound. 





Main Structure and Functions


The default control panel is set to ‘Overview’ mode and users can switch to ‘Detail - General/Room’ or ‘Detail - Damping/EQ’ mode by a click of the button on the panel. Each of the ‘Detail’ mode provides parameters for reverb controls that are not dealt with in ‘Overview’ mode and these parameters are employed to adjust a precise or a dramatic control of a reverb structure. To quickly catch up the use of Atomic Reverb, let’s take a look at the major features of the interface. 




▲ Reverb, Equalizer, and Damping properties visualization

This window shows reverb, equalizer, and damping properties. The left display visualizes duration of the reverb, stereo width, amplitude of the direct signal (dry signal), early reflections and late-reverb (reverb-tail), and output level of dry stereo-signal (D) and wet (reverberated) stereo-signal (W). The right display shows the curve of the EQ, damping settings, and a spectrum-analyzer of the processed signal. The spectrum analyzer is useful for monitoring the frequencies of the signal during settings of selective EQ and damping parameters.





▲ Properties and Parameter pages (The 'Overview' page)

The Properties and Parameter pages provide buttons and controls to adjust the reverb presets and consist of three different pages - ‘Overview’, ‘Detail - General/Room’, and ‘Detail - Damping/EQ’. The ‘Overview’ page is the default parameter page and supports access to the most common parameters to define a reverb-room. Each control of the ‘Overview’ page is a copy of the corresponding control from the ‘Detail’ pages. All parameters which are not part of the ‘Overview’ page are accessible via the ‘Detail’ pages.   





▲ Properties and Parameter pages (The 'Detail - General/Room' page)

The parameters of ‘Detail - General/Room’ page are divided into the four categories of reverb properties such as ‘General’ (general preset properties), ‘Room’ (room properties), ‘ER’ (properties of the early reflections), and ‘Tail’ (properties of the reverb-tail). In the ER menu bar, users can make a choice of a room type to simulate a specific type of early reflections in almost any situation. Atomic Reverb offers two ways to calculate the reverb-tail: Type-D (“Dense”) immediately creates a full diffuse reverb-tail without initial coarse reflections and allows large attack-times and absorption but no modulation. Type-R (“Room”) creates initial coarse reflections with growing diffusion depend on the room size and allows modulation and sparse attack but no absorption. The ‘Stretch’ parameter enables a fine-adjustment of an already set room-size and thus changes the sound of the early reflections. ‘Gate Thres.’ means “a threshold for gated reverberation” and this effect is commonly used for percussive instruments such as snare drums to produce a saturated but not-too-long reverb. The ‘Absorption’ parameter - used only for ‘Type-D’ reverb-tail - controls strength of wall-absorption of a room and the ‘Movement’ parameter - used only for ‘Type-R’ reverb-tail - controls strength of air movement in a room. 





▲ Properties and Parameter pages (The 'Detail - Damping/EQ' page)

In the ‘Detail - Damping/EQ’ page, the damping and EQ properties specify the frequency response of a room. The top ‘Damp low/mid’ switch defines whether the low or mid frequencies will be damped. The frequency range which is damped will have a shorter decay time than the un-damped. ‘Damp L/M’ and ‘Damp High’ control low or mid and high frequency damping levels respectively. These two parameters are used for determining attenuation strength of each selected frequency range. ‘Range L/M’ and ‘Range High’ specify the frequency range where below or above it damping is performed. These parameters are used to fine adjust a room character. The settings of EQ parameters define the sound color of the reverb effect. The EQ always processes after the reverb-effect processing, so it changes only the sound of a wet signal.






▲ Preset selection and handling menu

Atomic Reverb uses a central storage place for presets. As a result, all of users’ saved presets are visible in all instances of the plugin, regardless what DAW or VST host program you are working with. At the top of ‘Preset selection and handling’ menu, users can use the buttons ‘Fact’ or ‘User’ to switch to the factory presets list or to the user-created presets. 














Atomic Reverb supports parameter controlling via MIDI events, so users can assign various parameter knobs to different MIDI controllers. Atomic Reverb can be run as a standalone application under Windows system.

MolecularBytes GbR. MolecularBytes GbR., founded by the twin-brothers AndrÈ Hugenroth and Frank Hugenroth, who have been involved in the development of music and audio software and methods since the early 1990s. Under the name MolecularBytes, a preview version of an elastic audio software was published at the end of 2005. The first commercial product was “AtomicReverb", and it was soon followed by “AtomicTransient". In addition to these effect plug-ins, now we are focusing on the completion of the audio editing software "Membrane".
