diffraction using a secondary edge-source
method based on a discrete Huygens
interpretation of Biot-Tolstoy. As a background
a 20+ page whitepaper document is included
in the documentation and discusses the implementation
as well as diffraction in general. The white paper
explains why this particular implementation
was chosen instead of a screen formula that has many
limitations and questionable applicability in
room acoustics. The chosen implementation also gives
considerably more than a screen formula could
such as more correct reflections from small surfaces
and also helps modeling concave and convex curved surfaces
approximated by facets.

- The FIReverb
Suite™,
4th Edition (18-MAY-2007)
- PureVerb™
creates a new PureVerb
eXtended (PVX) file format.
PVX is a single-file, multi-input,
multi-output, multi-microphone
impulse response format that also stores
a PureVerb settings-file.
A PVX-file can be loaded by File|Open
for examining the parameters used when
creating the impulse responses, or to re-calculate
the same basic responses after some
changes in parameters. The PVX-format
simplifies use of PureVerb responses in
MultiVolver™ since only one file needs
to selected for a complete set of filters.
- the
new PvxViewer shows the contents
of a PVX-file, impulse responses,
octave-band filtered impulse responses
and decays.
- PureVerb
and MultiVolver
optionally creates WAV-files
in WAVE-EX format.
