The minimum source distance is the distance at which sounds
have unity gain (that is, they are not made louder or softer when
they are within this range). This facility is provided to prevent
excessive gain — and possible hearing damage to a listener —
when a sound object comes very close to the listener object.
• Type the distance in virtual meters into the Minimum
source distance box.
All instances of the Sound Field Filter require 2 DSPs for
reverberation filters.
Each sound source used in the simulation requires 1 DSP.
For example, When the Sound Field Filter boots up, it uses 3
DSPs: two for the reverberation filters and one for the preloaded
sound source.
• The Sound Field Filter receives audio from inputs
characterised as Sound objects, encodes them in B-format,
and convolves them through a room response to produce Bformat
encoded output.
• The Sound Field Filter defines which SNAP or
Locatorchannels the positional and rotational information of
each object will be passed over. Positional and rotational
information can be unique to each object or use a relational
system. Under the relational system, positional and
rotational information is passed over a set of linked
channels.
• The Sound Field Filter allows the definition of a Listener
object (receiver) and Sound objects to be used in the
AniScape suite of simulation tools.
