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 DeVerberate is available for both Windows (PC) and OS X (Macintosh). Both 32 and 64 bit versions are available, and the plug-in formats VST, VST3, AAX and Audio Units (OS X only) are supported.

Acon Digital Restoration Suite - VST audio filters

When shooting a video sequence you cannot always avoid recording some noise. Sometimes you might find out only in the editing suite that there are some disturbing audio signals in your footage.

To fix this in the postproduction is usually very time consuming and often does not lead to the hoped for results.
How often do you have failed to remove noise like hiss, wind noise or broadband noise from important scenes?
With ACON Digital Restauration Suite for EDIUS it is possible to reduce different kind of noise in less time and good quality.

Great efforts have been put into preserving as much of the 
original signal and it’s character as possible during the noise reduction process.

The ACON Digital Restauration Suite for EDIUS consists of four audio restoration plug-ins that can be combined individually:

DeNoise is designed to reduce stationary noise such as broadband noise, hiss, wind noise, buzz and camera noise. 
You can freeze the noise profile anytime in order to perform the actual noise reduction.

Experts recommend operating a camera manually instead of relying on automatic functions. 
This avoids disturbances regarding the volume, which occur when the automatic recording level control tries to set the level of an air condition in the background to the same level of the spoken words of an interviewee. 
But when setting the recording level manually clipping can occur. This happens during recording when the recording level is too high and the highest peaks cannot be correctly recorded. 
DeClip substitutes such distorted peaks with an estimation of the signal curve.

Conclusion

ACON Digital Restauration Suite for EDIUS can be used perfectly in combination with Voxengo Voxformer. It allows you to have best audio quality for your EDIUS productions – for a small price. 

Tip: ACON Digital Restauration Suite for EDIUS is the optimal solution for users new in audio editing as well as a reasonably priced alternative for former users of ReduNoise, a 32-bit application which cannot be integrated in EDIUS 8/9 any longer. ACONoffersbetter performance and more options to improve your audio for a reasonable price.
