Abstract: A decoder generates decoded signals based on quantized signals. The decoder includes an inverse quantizer and a predictor circuit. The quantized signals are generated in an encoder by low-pass filtering an input signal and encoding the filtered signal using adaptive differential pulse code modulation. The predictor circuit has filter coefficients based on a frequency response of the low-pass filter used to filter the input signal.

Abstract: An encoder generates quantized signal words based on a difference signal. The encoder includes an adaptive quantizer. A step size applied by the adaptive quantizer is generated in a feedback loop and based on a loading factor and quantized signal words generated by the adaptive quantizer. The encoder includes coding circuitry which generates code words based on quantized signal words generated by the adaptive quantizer. The coding circuitry generates an escape code in response to a quantized signal word not being associated with a corresponding coding code word.

Abstract: Application servers having multiple virtual machines are restarted by sequentially addressing each active virtual machine (VM) by adding a corresponding new VM prior to stopping the active VM before adding another new VM corresponding to another of the multiple virtual machines to be restarted. Application servers are monitored for restart conditions that trigger a sequential process of adding a new VM and stopping the corresponding active VM.

Abstract: An encoder includes a low-pass filter to filter input audio signals. The low-pass filter has fixed filter coefficients. The encoder generates quantized signals based on a difference signal. The encoder includes an adaptive quantizer and a decoder to generate feedback signals. The decoder has an inverse quantizer and a predictor. The predictor has fixed control parameters which are based on a frequency response of the low-pass filter. The predictor may include a finite impulse response filter having fixed filter coefficients. The decoder may include an adaptive noise shaping filter coupled between the low-pass filter and the encoder. The adaptive noise shaping filter flattens signals within a frequency spectrum corresponding to a frequency spectrum of the low-pass filter.

Abstract: Embodiments disclosed herein generally relate to techniques for managing processing of data in computing systems. One embodiment provides a method which includes receiving a set of inputs to apply to at least a first big data definition. Each big data definition encapsulates information specified in the set of inputs into a set of reusable software components. The method also includes generating, based on the reusable software components, a first executable code component for the at least first big data definition. The method further includes deploying the first executable code component to an executing application without interrupting services provided by the executing application to which the first executable code component is deployed.

Abstract: An adaptive noise shaping filter flattens signal components below a threshold frequency range in a filtered signal to be encoded. An encoder generates quantized signals based on a difference signal and includes an adaptive quantizer and a decoder. The decoder generates feedback signals and has an inverse quantizer and a predictor. The predictor has determined control parameters based on the threshold frequency range.

Abstract: A method and apparatus processes multi-channel audio by encoding, transmitting or recording “dry” audio tracks or “stems” in synchronous relationship with time-variable metadata controlled by a content producer and representing a desired degree and quality of diffusion. Audio tracks are compressed and transmitted in connection with synchronized metadata representing diffusion and preferably also mix and delay parameters. The separation of audio stems from diffusion metadata facilitates the customization of playback at the receiver, taking into account the characteristics of local playback environment.

Abstract: Devices and methods are adapted to characterize a multi-channel loudspeaker configuration, to correct loudspeaker/room delay, gain and frequency response or to configure sub-band domain correction filters.

Abstract: An array loudspeaker includes a plurality of drivers arranged in an array configuration. A digital signal processor-based control system processes direct audio signal and indirect audio signal inputs for the loudspeaker to simultaneously produce direct sound in the form of a directed beam or wavefront, and indirect sound as a perceptually diffuse soundfield.

Abstract: The present invention provides a novel end-to-end solution for creating, encoding, transmitting, decoding and reproducing spatial audio soundtracks. The provided soundtrack encoding format is compatible with legacy surround-sound encoding formats, so that soundtracks encoded in the new format may be decoded and reproduced on legacy playback equipment with no loss of quality compared to legacy formats.
