Acon DeVerberate 2 – Reverb Reduction Plug-in

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). There are 32 and 64 bit versions for Windows and the Mac version is 64 bit. The plug-in formats VST, VST3, AAX and Audio Units (OS X only) are supported.
