Info

The simulated acoustic spaces used in AniScape are implemented in real-time using a highly detailed room response supplied by a modelling packages such as CATT- Acoustic, CATT-VRoom (a simplified room generation package) or Lake Technology’s MakeRoom utility. THE SIMULATION TOOLS the simulated space they inhabit. This generalised format is composed of four standard audio signals and may be decoded to speakers using the Speaker Decoder or decoded to headphones using the Binaural Decoder. The B-format signals may also be recorded to multi-track tape or disk and are identical to the format produced by a sound field microphone. HURON TECHNICAL MANUAL PAGE 90
Features Operation Starting The Sound Field Filter The Sound Field Filter simulation application is an integral part of the AniScape simulation suite. The Sound Field Filter takes data from inputs and encodes it into a stream of spatialised Bformat data. This data is then filtered through a room response to give an output which may be further processed by the AniScape Decoder tools, Speaker Decoder or the Binaural Decoder, to produce three-dimensional sound simulations. • The ability to add a listener and multiple sound objects to a three-dimensional Soundscape. • The ability to load various acoustically modelled rooms for spatial convolution. • The ability to set a minimum source distance for unity gain. Figure 30 — The Sound Field Filter interface The Sound Field Filter must be loaded into the VRack from the New/Simulation Tools submenu (for loading instructions see the System Tools section of this manual).
