Linear Phase HURON TECHNICAL REFERENCE Linear phase is characterised by a constant time delay corresponding to a phase shift increasing linearly with frequency. Location Channels Are communication channels for transferring locational information of a Lake Technology AniScape or MultiScape simulation object. Low Latency Low latency is characterised by a short delay during signal processing. Optimum Phase By reducing optimum phase in Lake Technology’s EQ application, filters can be programmed to have zero or minimum phase delays. As a trade off for this low delay, phase distortion may occur. Reverberation The reflections of a sound source from the surfaces of a room or environment. RMS Root-mean-square amplitude of a sine wave. Roll The orientation of an object around a central point. Values start at 0.00 when the object is standing upright and increase as the object rotates clockwise, up to 360.00. Sample Rate Digital playback and recording is achieved by measuring the level of input signals at a specified sample rate. For instance at 48kHz 48,000 samples of data are taken every second. SNAP SNAP (Spatial Network Audio Protocol) is a protocol written to facilitate communication between an external application and Huron VRack applications. SNAP communicates with the Socket application using TCP/IP. HURON TECHNICAL MANUAL PAGE 308
SNR (Signal to Noise Ratio) HURON TECHNICAL REFERENCE The signal to noise ratio is defined as: The ratio in dB of the rms voltage to the rms voltage of the noise present. T60 The time taken for a sound to drop (diffuse) 60 dB. TDM Channel A Time Division Multiplex Channel. Time Domain A common way of referring to the mathematical representation of signals, where the signal is displayed in terms of its components over time. Transaural Playback of a three-dimensional soundfield through a pair of speakers. Transaural playback often requires crosstalk cancellation to provide three-dimensional sound. XYZ Coordinates The XYZ coordinate system utilised by Lake Technology simulation tools represents the three axes of a three dimensional coordinate system. X and Y represent the coordinates on a horizontal plane, while the Z axis represents the vertical component of the system. HURON TECHNICAL MANUAL PAGE 309
