Summary THE SIMULATION TOOLS • MultiScape provides an integrated set of tools for multiple people multi-room, multi-user acoustic simulations. • It provides the ability to add Sound objects, Speaker Arrays and Headphones to a virtual Soundscape. • It provides fully featured room and door effects, which can be updated in real-time. HURON TECHNICAL MANUAL PAGE 116
Features Operation HeadScape HeadScape is a subset of the simulation tools used for accurate headtracked auralisation. HeadScape allows the implementation of highly accurate localisation of sounds over headphones. • HeadScape utilises a filter switching technique to provide accurate aural simulations controlled by a headtracked pair of headphones. • HeadScape uses responses derived from acoustic modelling software in order to obtain accurate room responses for use in simulations. HeadScape is Lake Technology’s premier head-tracked auralisation system. Designed for critical evaluation of room acoustic simulations, HeadScape makes use of Lake Technology’s proprietary low-latency long convolution technology to switch long FIR filters smoothly and efficiently in response to the listener’s head movement. To create a consistent and realistic simulation HeadScape employs a two stage filtering process. The late part of the room’s impulse response is kept fixed but the early part is selectively switched depending on the listener’s head position. The early part is of the order of 4000 samples long and includes a binaural representation of the early reflections in the space. This feature enables HeadScape to create virtual sound objects that are strongly and clearly externalised. HURON TECHNICAL MANUAL PAGE 117
