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.
