    Abstract: A method, system and computer program product for detecting and displaying potentially volatile data. A metadata store, which is attached to a data store, is used for storing metadata corresponding to the stored data. A data retrieval component is used for retrieving a first and a second subset of data from the data store. Furthermore, a metadata retrieval component is used for retrieving a first and a second subset of the metadata corresponding to the first and second subsets of data from the data store. In addition, a comparator is used for comparing the first and the second subsets of the metadata. Additionally, a display control component, responsive to the comparator, is used for varying an indicator associated on a display with the first subset of data or the second subset of data to indicate an inconsistency between the first subset of metadata and the second subset of metadata.

  • Patent number: 10321256
    Abstract: Systems, methods, and computer program products for creating an object-based audio signal from an audio input are described. The audio input includes one or more audio channels that are recorded to collectively define an audio scene. The one or more audio channels are captured from a respective one or more spatially separated microphones disposed in a stable spatial configuration. A system receives the audio input. The system performs spatial analysis on the one or more audio channels to identify one or more audio objects within the audio scene. The system determines contextual information relating to the one or more audio objects. The system defines respective audio streams including audio data relating to at least one of the identified one or more audio objects. The system then outputs an object-based audio signal including the audio streams and the contextual information.

  • Patent number: 10318235
    Abstract: In an audio encoder, for audio content received in a source audio format, default gains are generated based on a default dynamic range compression (DRC) curve, and non-default gains are generated for a non-default gain profile. Based on the default gains and non-default gains, differential gains are generated. An audio signal comprising the audio content, the default DRC curve, and differential gains is generated. In an audio decoder, the default DRC curve and the differential gains are identified from the audio signal. Default gains are re-generated based on the default DRC curve. Based on the combination of the re-generated default gains and the differential gains, operations are performed on the audio content extracted from the audio signal.

  • Patent number: 10306363
    Abstract: A method for operating a distributed wireless audio system including several loudspeaker cabinets all of which can communicate with each other as part of a computer network. The method receives temperature data that is indicative of temperature of a first loudspeaker cabinet, which has a network master responsibility of obtaining an audio signal from an audio source and wirelessly transmitting some of the audio signal to a second loudspeaker cabinet of several loudspeaker cabinets, for playback by the second loudspeaker cabinet, while playing back some of the audio signal by the first loudspeaker cabinet. The method determines whether a thermal threshold of the first loudspeaker cabinet has been reached, based on the temperature data. The method, in response to the thermal threshold being reached, gives up the network master responsibility from the first loudspeaker cabinet to the second loudspeaker cabinet, where doing so reduces temperature in the first loudspeaker cabinet.

  • Patent number: 10306348
    Abstract: Techniques for mute pattern injection for a pulse-density modulation microphone are described. In one or more implementations, a pulse-density modulation (PDM) microphone includes a transducer that receives a pressure wave and produces an analog signal that represents the pressure wave, an analog-to-digital converter (ADC) that receives the analog signal from the transducer and converts the analog signal into a digital PDM signal. The PDM microphone also includes a pattern generator that generates a digital mute signal, a controller that outputs control signals, and a multiplexer that receives the control signals, the digital mute signal, and the digital PDM signal. The multiplexer transmits the digital mute signal or the digital PDM signal, responsive to the control signals.

  • Patent number: 10299041
    Abstract: A system is provided to analyze cross-modulation distortion in audio devices, which may include testing with audio frequencies. One or more distortion signals from the audio device may be measured for an amplitude, phase, and or frequency modulation effect. In another embodiment a musical signal may be used as a test signal. Providing additional test signals to the audio device can induce a time varying cross-modulation distortion signal from an output of the audio device. Also utilizing at least one additional filter, filter bank, demodulator and or frequency converter and or frequency multiplier provides extra examination of distortion. Also frequency and or phase response can be measured with the presence of a de-sensing signal and or another signal that induce near slew rate limiting or near overload condition of the device under test.

  • Patent number: 10297261
    Abstract: The present invention provides improvements to prior art audio codecs that generate a stereo-illusion through post-processing of a received mono signal. These improvements are accomplished by extraction of stereo-image describing parameters at the encoder side, which are transmitted and subsequently used for control of a stereo generator at the decoder side. Furthermore, the invention bridges the gap between simple pseudo-stereo methods, and current methods of true stereo-coding, by using a new form of parametric stereo coding. A stereo-balance parameter is introduced, which enables more advanced stereo modes, and in addition forms the basis of a new method of stereo-coding of spectral envelopes, of particular use in systems where guided HFR (High Frequency Reconstruction) is employed. As a special case, the application of this stereo-coding scheme in scalable HFR-based codecs is described.
