Abstract: A receiver for decoding associated compressed video and audio information components transmitted in mutually exclusive "frames" of data with respective time stamps PTS vid and PTS aud respectively, includes a controller which is responsive to the respective received time stamps to provide coarse synchronization by delaying or skipping respective frames of one or the other of the components to approximately time align the two components. Fine synchronization is provided by adjusting the processing or clock frequency of the audio signal processor independent of the video processor. The control for the frequency adjustment is related to the difference between audio and video time stamps.
TL;DR: In this paper, the authors describe a control system that is responsive to an audio signal generated by an audio source such as a computer, a video game console, a stereo system and a vibrating seat pad.
Abstract: A control system (100) that is responsive to an audio signal (104) generated by audio source such as a computer (102), video game console (102), stereo system and the like. The control system (100) converts the audio signal (104) into a control signal for a vibrating seat pad (110), and the like. The control system contains an audio signal processor (112) and a control signal generator (114). The audio signal processor (112) produces a processed change of the audio signal. From the processed signal a control signal (108) is generated. The control signal causes the tactile sensation generator to produce tactile sensation corresponding to the present scene being displayed, for example, on a monitor of a computer executing a computer game.

Abstract: A control system that is responsive to an audio signal generated by an audio source such as a computer, video game console, stereo system and the like. The control system converts the audio signal into a control signal for a tactile sensation generator such as a vibrating cushion, vibrating seat pad, and the like. The control system contains an audio signal processor and a control signal generator. The audio signal processor produces a processed signal indicative of the amplitude, frequency, and rate of change of the audio signal. From the processed signal, a control signal generator produces a control signal for a tactile sensation generator. The control signal causes the tactile sensation generator to produce a tactile sensation corresponding to the present scene being displayed, for example, on a monitor of a computer executing a computer game.
TL;DR: An audio system includes a memory storing audio data and an audio signal processor for processing the audio data as discussed by the authors, where addressing circuitry addresses the memory and a pre-fetch storage area stores data for a current address and for one or more following addresses.
Abstract: An audio system includes a memory storing audio data and an audio signal processor for processing the audio data. Addressing circuitry addresses the memory and a pre-fetch storage area stores data for a current address and for one or more following addresses to hide memory access latency during address changes of the addressing circuitry.
TL;DR: In this paper, a frequency-dependent linear audio signal processor takes source signals S in input signals and provides directionally spread directionally encoded output signals, where the processor directionally encodes with constant gain magnitude frequency components of the source signal S to-and-fro across a predetermined directional stage P" as frequency increases such that at least three predetermined positions within the stage P have substantially zero perceived phasiness.
Abstract: A frequency-dependent linear audio signal processor takes source signals S in input signals and provide directionally spread directionally encoded output signals. The processor directionally encodes with constant gain magnitude frequency components of the source signal S to-and-fro across a predetermined directional stage P" as frequency increases such that at least three predetermined positions within the stage P", the directional encoding has substantially zero perceived phasiness. The processor may be a frequency-dependent rotation matrix for stereo input signal and may be a unitary network using a feedback path around parallel identical all-pass networks in series with a rotation matrix and a feedforward path bypassing the all-pass networks. Successive frequencies of positioning of source signal S at a predetermined position P within the stage P" are preferably spaced approximately uniformly on a logarithmic or Bark Frequency scale. Several sources S may have individually adjustable spreads while sharing common processor.
