Experience the Revolutionary Vivid Hall Algorithm in 3D

Verberate Immersive 2 is a surround reverb and a 3D capable edition of Verberate 2 — our algorithmic reverb plug-in that simulates real acoustical spaces with exceptional realism. Verberate Immersive 2replaces Verberate Surround and supports all common surround and immersive formats up to 7.1.6 channels. The new Vivid Hall algorithm adds time variance to avoid the stiffness that plagues convolution based reverbs while preserving the natural high density reverb tails of Verberate Surround 1.

Verberate Immersive 2 was developed in close cooperation with professionals in film and TV post production. Great efforts were made to create a tool that not only delivers best-in-class audio quality, but also delivers results quickly through a well thought out workflow. Verberate Immersive 2 offers complete and independent control over the panning of the dry sound, late reverberation and early reflections. The panners work in up to three dimensions and have adjustable divergence. The pan positions and divergences are visualized and adjusted in an intuitive way, thus simplifying automation of complex movements.

Audio source placement in three dimensions using the integrated panner in Verberate Immersive 2. The direct, reverb and early reflections can be panned independently.

The decay editor resembles a fully parametric equalizer and allows you to set frequency dependent reverb times quickly and effortlessly. Additionally, there are integrated and fully parametric input and output equalizers, each with five bands.

The decay editor allows you to sculpt the reverb tails through frequency dependent reverb times.

A large catalog of beautiful factory presets is delivered with Verberate Immersive 2. A search button allows you to find the desired preset quickly. A clear and to-the-point graphical user interface simplifies the search for a specific reverb quality.

Verberate 2 with the Revolutionary Vivid Hall Algorithm

When it comes to reverb, it’s all about the sound quality. Verberate is an algorithmic reverb plug-in that simulates real acoustical surroundings with exceptional realism. The first Verberate version already raised the bar. Version 2 introduces the Vivid Hall algorithm that adds time variance to avoid the stiffness that plagues convolution based reverbs while preserving the natural high density reverb tails of Verberate 1.

Real acoustical surroundings will have slight variations due to air currents, moving performers or movements in the audience. While these variations may seem subtle, the effect towards the end of the reverb tail is significant, since the sound is reflected a large number of times before the reverb tail fades out. The new Vivid Hall algorithm models these random variations without artifacts like chorus effects or pitch changes, and is therefore capable of simulating reverberation of real halls with a higher degree of realism.

The decay editor that makes it possible to sculpt the reverb tails by setting up frequency dependent reverb times. There is also a powerful output equalizer integrated.

Another new feature is the ability to better simulate mechanical plate reverbs. High frequencies travel faster in metal plates than low frequencies, and this effect is called frequency dispersion. Verberate 2now has a Dispersion parameter which allows for highly realistic plate reverb simulations when combined with the decay editor to simulate the longer high frequency decay of plate reverbs. A new Swirl parameter makes it possibly to simulate the feedback modulation effect found in many vintage digital reverb units.

The 15 early reflection patterns offered are algorithmic, calculated in real time and applied using convolution. A dense and resonance free late reverb tail follows the early reflections, resulting in extremely convincing room simulations with impressive depth combined with the flexibility algorithmic reverbs are known for.

A large catalog of beautiful factory presets is delivered with Verberate 2 and a clear and to-the-point graphical user interface simplifies the search for a specific reverb quality.

Highlights

• Highly realistic simulation of real acoustical spaces and mechanical plates
• The new time variant Vivid Hall algorithm goes beyond convolution
• Powerful decay editor allows frequency dependent reverb times
• Versatile integrated output equalizer

The new DeVerberate 2 — now with Early Reflections Filter

DeVerberate is a reverb reduction plug-in that can attenuate or boost the reverberation that is already present in recorded material. The novel real-time algorithm works equally well with mono as with stereo recordings and splits the incoming audio into an estimation of the direct sound and the reverberated sound which can then be recombined freely. The improvement process can be monitored visually using the spectral representations of the input and output signal as well as of the estimated reverberation.

DeVerberate 2 introduces a new and unique Early Reflections Filter that works in conjunction with the late reverb suppression found in version 1. The Early Reflections Filter uses sophisticated statistical methods to estimate the so called impulse response of the early reflections. The impulse response is then utilized to calculate an inverse filter that cancels out the effect of the early reflections.

Use Cases

• Improve dialog and location sound
• Forensic specialists can improve speech intelligibility
• Attenuate reverberation in existing recordings
• Boost the natural reverberation in existing recordings
• Change the perceived distance in a mix by changing the balance between the direct sound and the reverberation

Acon Digital Mastering Suite consists of five plug-ins for audio mastering that were designed for ultimate signal transparency:

Equalize

Equalize is a parametric equalizer. Unlike other equalizers, you can freely adjust not only centre frequency, gain and bandwidths, but also the filter slope for each band. The filter slope can be set anywhere from 3 dB to ultra-sharp 120 dB per octave. You can operate Equalize as a zero latency plug-in when using the minimum phase mode, choose to preserve the phase relationships in the linear phase mode or use the unique mixed phase mode. The mixed phase mode allows you to set the latency freely in the range 5 to 120 milliseconds while preserving the phase relationships as far as possible. That gives a unique control over potential pre-ringing artifacts which is a common problem with linear phase filtering.

Dynamics

Dynamics is a combined compressor, expander or gate. The look-ahead can be set anywhere from 0 to 30 milliseconds and the intelligent algorithm ensures a band-limited gain signal which reduces potential distortion to a minimum even with minimal attack and release times. You can use up to 4 times oversampling to further reduce distortion. The side chain signal can be either internal or external and there’s a full blown side chain equalizer integrated with low cut, low shelf, peak, high shelf and high cut filters. The complexity of algorithms is not reflected in the intuitive user interface which provides graphical visualizations of all aspects of the processing.

Multiband Dynamics

Multiband Dynamics is the multiband extension of Dynamics which allows dynamic processing in up to four separate bands. You can freely set the cross-over frequencies and even the filter slopes can be set freely in the range 6 and 48 dB per octave. Multiband Dynamics operates in linear phase mode to avoid phase issues between the processed bands.

Limit

Limit is a transparent limiter with intelligent look-ahead in the range 0 to 30 milliseconds that reduces distortion to a minimum. The limiting is performed in a two step process with a pre-compressor follower by the actual peak limiting algorithm. You can use up to 4 times oversampling for true peak limiting and to further reduce distortion.

Dither

Dither is a dithering plug-in with flexible perceptual noise shaping. You can adjust the maximum gain and the filter length of the frequency response of the noise shaping filter is visualized graphically.

System Requirements

PC Version (Windows)

• Windows 10 / 8 / 7
• Intel Core i3 or AMD multi-core processor (Intel Core i5 or faster recommended)
• 1366 x 768 display resolution (1920 x 1080 or higher recommended)
• 1 GB RAM (4 GB or more recommended)
• 1 GB free HD space
• A host application that is compatible with VST, VST3 or AAX (Pro Tools 10.3.5 or higher)

Macintosh Version (OSX)

• OS X 10.8 or later
• 1 GB RAM (4 GB or more recommended)
• 1 GB free HD space
• A host application that is compatible with AU, VST, VST3 or AAX (Pro Tools 11 or higher)

DeFilter is an efficient tool to even out tonal imbalances in a recording or reduce resonant peaks or dips in the frequency spectrum. Even severe issues such as comb filter effects or standing waves from untreated rooms can be addressed. DeFilter can match recordings to target profiles such as music or speech, or alternatively extract the overall timbre from the source – the large strokes – while evening out narrow peaks and dips. The latter removes resonances and comb filter effects effectively while preserving the tonal character of the input signal. Recordings can also be equalized to match a reference recording.

Great care has been taken to provide a user interface that is straightforward to use. Frequency dependent correction levels can be defined using custom curves, so that DeFilter can focus on problematic frequency ranges while leaving other frequency regions untouched. Realtime spectrum analyzers for both the input and output signals visualize the effect on the frequency spectrum.

Use Cases

• Fix issues in a mix prior to mastering
• Reduce resonances caused by untreated room acoustics
• Matched equalization (automatic equalization based on a reference signal)
• Improve clarity and intelligibility of speech
• Instant fix for nasty comb filter effects

A Giant Leap in Audio Quality

Restoration Suite 2 is a suite of four cutting edge plug-in for audio restoration and noise reduction.

New in Version 2

All four plug-ins have received major improvements both in the processing algorithms and the user interface compared to version 1. DeNoise 2 introduces the novel dynamic noise profiles that help reducing noise that varies randomly over time, such as wind noise or rustle from lavalier microphones. Where the earlier versions merely captured a static noise print with time-constant noise levels, the dynamic noise profiles capture statistics from the noise to be reduced. The noise suppression algorithm then estimates the most suitable noise threshold curve for the noisy input signal using the measured statistics.

DeNoise 2, DeClick 2 and DeHum 2 now support Mid/Side (M/S) processing, which can reduce unwanted fluctuations in the stereo image. The core algorithm in DeClick 2 received major improvements and now better preserves transients and can be pushed to higher click and crackle sensitivities without introducing artifacts.

DeHum 2 has a new automatic fine-tune button that triggers automatic estimation of the hum noise frequency. The hum tracking and suppression have also been improved. DeClip 2 was improved in terms of audio quality and now offers even more impressive reconstruction of clipped signal peaks. All the plug-ins in the suite now support surround and immersive audio formats up to 7.1.6 channels.

Acon Digital Restoration Suite 2 is available as VST, VST3 or AAX for both Windows and Mac or as AU plug-ins for Mac. There are 32 and 64 bit versions for Windows and the Mac version is 64 bit.

DeNoise 2

DeNoise 2 is a plug-in designed to reduce noise such as hiss, wind noise, buzz and camera noise. The noise can be reduced automatically in the adaptive mode or after measuring the characteristics of the noise in the noise profile mode. New in version 2 are dynamic noise profiles that capture the dynamic properties of the noise so that noise that fluctuates over time, such as wind noise, can be effectively reduced. The new algorithm has also been greatly improved and is now even less prone to typical de-noising artifacts.

Features

• Advanced algorithms reduce stationary noise efficiently with minimal impact on the wanted material
• Reduces noise in adaptive mode or based on noise analysis.
• Novel dynamic noise profiles makes it possible to remove noise that changed rapidly over time
• Transient detection ensures that transients remain untouched throughout the noise reduction process
• Effective temporal smoothing reduces “musical noise” artifacts
• Optional M/S processing
• Target broadband and tonal noise or optionally broadband only
• Graphical representation of input frequency spectrum and the noise profile
• Frequency emphasis filter:
  • High and low shelving filters with variable slopes (-3 to -96 dB / octave)
  • High and low peak filters with adjustable bandwidth (0.1 to 3.0 octaves)
  • Graphical representation of frequency response
  • Editing of filter settings through handles in the frequency response curve
• Solo Noise mode allows you to listen to the removed signal

DeHum 2

DeHum 2 targets hum and buzz typically introduced by poorly grounded electrical equipment, but also other tonal noise sources like electrical motor noise. The hum detection algorithm has been improved in version 2 and there’s now a new Scan button that automatically fine tunes the fundamental hum frequency.

Features

• Remove hum and buzz with minimal loss of the wanted signal
• Novel sinusoidal re-synthesis algorithm (preserves wanted signal to a much larger extent) or conventional notch filter mode
• Adaptive mode allows removal of hum signals with a fluctuating fundamental frequency
• New automatic fine-tune button looks automatically scans the fundamental frequency
• Removes up to 96 harmonics
• Optional M/S processing
• Option to target only odd harmonics
• High resolution spectrum analysis of the input signal
• Visual indication of the estimated fundamental frequency as well as the harmonics
• Solo Hum mode allows you to listen to the removed signal

DeClick 2

DeClick 2 is designed to remove impulsive noise such as clicks, crackle and thumps. These distortions are frequently encountered on LP and 78 RPM records, but also occur in digital recordings due to drop-outs or distorted data packets. DeClick 2’s thump reduction works also effectively on vocal recordings with unwanted plosives. The algorithm has been improved in version 2 and is now less prone to reducing attacks and transients in the wanted signal.

Features

• Seperate detection and restoration of clicks, crackle, thumps and plosives
• Very accurate detection of click start time and duration ensures minimal impact on the wanted material
• Improved algorithm allows higher sensitivities without artifacts
• CPU efficient algorithm
• Optional M/S processing
• Visual curve meters show the clicks and crackle removal rates
• Residual signal mode allows you to listen to the removed signal

DeClip 2

DeClip 2 restores audio recordings distorted by analog or digital clipping with an improved algorithm.

Features

• Reconstructs peaks distorted by analog or digital clipping
• Improved algorithm over version 1.x
• Separately adjustable upper and lower threshold values
• Optional upper and lower threshold lock simplifies the workflow in the case of symmetrical clipping
• Graphical representation of the input and output level histograms makes it easy to set the threshold values and monitor the restoration process visually
• Threshold values can be adjusted directly from the level histograms by dragging upper and lower threshold handles

The new Equalize 2 — now with Tilt and Bandpass Filters

Acon Digital Equalize is a parametric equalizer plug-in that combines unique features with excellent workflow and an intuitive user interface. Unlike other equalizers, you can freely adjust not only center frequency, gain and bandwidths, but also the filter slope for each band. The filter slope can be set anywhere from 3 dB to ultra-sharp 120 dB per octave. Needless to say, you can operate Equalize as a zero latency plug-in when using the minimum phase mode or choose to preserve the phase relationships in the linear phase mode. Equalize goes one step further, though, and introduces the unique mixed phase mode that allows you to set the latency freely in the range 5 to 120 milliseconds while preserving the phase relationships as far as possible. That gives a unique control over potential pre-ringing artifacts which is a common problem with linear phase filtering. Latency values below 20 milliseconds ensure that any pre-ringing is masked by the temporal masking of the human hearing while preserving the time-alignment across the audible frequency range.

Great care has been taken to provide a user interface that is straight forward to use. Band parameters can be adjusted using handles directly in the graphical representation of the frequency response, including bandwidths and filter slopes. A flexible real-time analyzer lets you monitor every aspect of the processing. You can easily switch between full, mid, side, left or right channel processing for each band and Equalize automatically routes the audio signal internally to ensure the best results and lowest possible latency.

Highlights

• Eight different band filter types — low cut, low shelf, peak, tilt, bandpass, notch, high shelf and high cut
• Up to twelve independent bands
• Freely adjustable gain, frequency, bandwidth, resonance and filter slope
• Three different phase modes, including the novel mixed phase mode with adjustable latency
• Choose channel mode for each band independently (mid, side, left, right or full processing)
