Recently, sampling (convolution) reverbs have become more and more in demand.
With convolution, we have an opportunity to capture the sound of anything in the
world that can generate a reverb and use these sound impulses freely in any
situation imaginable. This enables us to use the sound of high-end reverb units,
real-world rooms, halls, cathedrals, synthetic reverbs and other sources,
including non-reverb ones, without any hassle and in a uniform way using only a
single program or a plug-in module.

Although there are many different sources of impulse responses, we also face the
difficulties of acquiring these so they can be used seamlessly in any software
environment.

In many cases during some stage of the impulse capture, we typically have a
rather large set of recorded test tones that were run through some device or
mic'ed in some room. This poses the difficulty of recovering the impulses
conveniently and with minimal user effort. The other problem we may face is the
input or the output bit-depth incompatibility of the recorded and the recovered
files. Some convolution plug-ins tend to support only a small subset of
available bit-depths. And alike, existing deconvolution programs and plug-ins
support only the given sample rates and bit depths, and tend to offer a very
poor quality deconvolution.

Voxengo Deconvolver overcomes these problems. First of all, it supports almost
all sample formats (bit-depths) of uncompressed mono/stereo WAV files. Secondly,
it offers a very convenient environment in which to deconvolve large sets of
recorded files. Voxengo Deconvolver also offers a true mathematical FFT
deconvolution which delivers 100% exact deconvolution. At the same time, this
puts a huge demand on the system memory: deconvolving a 25-second stereo file at
96 kHz may require up to 100 MB of memory.
