Introduction to the Simulation Tools The simulation tools are comprised of a number of separate VRack applications that provide simulation of threedimensional acoustic spaces over an array of speakers or a set of headphones. Binscape: Which provides facilities for simulating virtual acoustic spaces with multiple moving sound sources. Binscape uses binaural processing and optimised panning algorithms to provide high-end positional audio over headphones. Space Array: Which provides facilities for simulating multiple moving sound sources and three-dimensional virtual acoustic spaces. Featuring an optimised panning algorithm for speaker arrays, Space Array has an enlarged sweet spot and is suitable for personal or group presentations. AniScape: Which provides facilities for simulating threedimensional virtual sound spaces, where a single user can hear multiple moving sources through a speaker array or headphones. Aniscape is made up of a number of individual simulation tools, including Sound Field Filter, Speaker Decoder, and Binaural Decoder. Binscape and Space Array have superseded Aniscape for most simulation applications. MultiScape: Which provides facilities for simulating threedimensional virtual acoustic spaces, where multiple users can hear multiple moving sources by using a speaker array or headphones. Binscape and Space Array have superseded Multiscape for most simulation applications. HeadScape: Which provides facilities for using long, low latency FIR filters in combination with a head tracking device. This combination allows HeadScape to produce very accurate three-dimensional sound for high-end acoustic simulations. Sonic Animator: Which provides a graphical interface and panning tool for manipulating audio sound source location. Lake Technology provides a selection of Other simulation tools which integrate with the above tools and other Lake Technology VRack applications. These other tools include: Locator: Designed for testing and configuration verification, the Locator provides a visual interface to allow the positioning and movement of sound objects on a two dimensional plane. WavePlayer-2: An enhanced version of WavePlayer for play back of long duration Wave files (*.WAV) with zero Huron DSP usage. WavePlayer: Designed to play back Wave files (*.WAV) encoded in the *.SIM file format through the Huron system. Tracker: Allows the Huron to interface with a threedimensional position tracking system such as the Polhemus® HURON TECHNICAL MANUAL PAGE 65
