    摘要： A signal decode circuit is coupled to a buffer for each signal channel. A memory includes a shared area configured to store waveform data sets, each waveform data set including a sequence of coded waveform values specifying waveform step states. The shared area further stores delay data sets, each delay data set including a digital delay value for each signal channel defining a delay profile. A signal pointer addresses the shared area to read one waveform data set from the memory with the sequence of coded waveform values being selectively loaded into one or more of the buffers. A delay pointer addresses the shared area to read one delay data set from the memory with the digital delay values used to control delayed actuation of the signal decode circuits to decode the sequence of coded waveform values from the buffers and generate waveform signals in accordance with the delay profile.

    摘要： One embodiment of the present invention sets forth a technique for generating audio for a speaker system. The technique includes receiving an audio input signal, a first location associated with the audio input signal, a first geometric model of the speaker system, and a second geometric model of one or more surfaces in proximity to the speaker system. The technique also includes generating a plurality of output signals for a plurality of speaker drivers in the speaker system based on the audio input signal, the first location, and the first and second geometric models. The technique further includes transmitting the plurality of output signals to the plurality of speaker drivers, wherein the plurality of speaker drivers emit audio that corresponds to the plurality of output signals, the emitted audio rendering a sound corresponding to the audio input signal at the first location.
