AniScape
The AniScape suite is comprised of several simulation tools.
The three main tools are:
• The Sound Field Filter, which takes a number of input
signals and encodes them into a B-format data stream.
• The Speaker Decoder, which takes B-format encoded data
and decodes it through a speaker array.
• The Binaural Decoder, which works in the same manner as
the Speaker decoder, however B-format data is decoded so
that it may be used via headphones.
• Decoding of convolved B-format data to produce real-time
three-dimensional audio simulations.
• Easy integration with visualisation systems, utilising SNAP
messages for network control of source and listener locations
and positions.
• Allows the encoding of any number of input signals into Bformat
audio, dependent on the number of DSP cards
installed in the system.
• Virtual spaces or rooms for use in AniScape can be
generated using acoustic modelling software.
• Creates Doppler effects for moving sound objects.
• Provides up to eight sound reflections for each sound object.
• Allows the decoding of B-format data to headphones or to
arrays of up to forty speakers.
AniScape simulations provide a high degree of realism through
the use of proven acoustic modelling methods coupled with
Lake Technology’s long, low-latency convolution technology
(Lake Convolution). AniScape gives total control of the
locations of multiple sound objects and the listener object
within a virtual acoustic space.
Sound objects are encoded into a general three-dimensional
audio format called B-format by combining source object
location and angle information, the location and angle
information of the listener object and the acoustic properties of
