摘要： A method performed in an audio decoder for reconstructing an original audio signal having a lowband portion and a highband portion is disclosed. The method includes receiving an encoded audio signal and extracting reconstruction parameters from the encoded audio signal. The method further includes decoding the encoded audio signal with a core audio decoder to obtain a decoded lowband portion and regenerating the highband portion based at least in part on a cross over frequency and the decoded lowband portion to obtain a regenerated highband portion. The method also includes creating a synthetic sinusoid with a level based at least in part on a spectral envelope value for the particular subband and a noise floor value for the particular subband and adding the synthetic sinusoid to the regenerated highband portion in the particular frequency band specified by the location information. Finally, the method includes combining the lowband portion and the regenerated highband portion to obtain a full bandwidth audio signal.

摘要： A method and method of extracting information from a netlist. The netlist for a device under test (DUT) is read and a circuit selected to be transformed. Transformation candidates are identified using transformation specific criteria and verification methods are applied to prove the transformation is equivalent to the circuit being transformed. If the candidate transformation is equivalent to the circuit being transformed, the system commits to the transformation. If the candidate transformation is not equivalent to the circuit being transformed, the transformation is undone.

摘要： A seat position adjustment assembly including an anchor plate from which a plurality of slide bearings extend slidably received in guide slots formed in a slide plate enabling seat position adjustment and which can also function as a seat mount. Each bearing includes a slide bearing having a slide plate receiving channel and a retainer engagement channel receiving a keeper disposed between the anchor and slide plates anchoring the slide bearing to the anchor plate. Each keeper releasably engages the slide bearing, can straddle the bearing, can function as a spacer spacing the slide plate from the anchor plate, and can function as an upholstery retainer clip that holds part of an outer cover against the anchor plate. A seat latch arrangement can be disposed between the anchor and slide plates releasably retaining a seat removably coupled by the slide bearings to the slide plate in a desired seat position.

摘要： A system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates. The analyzer of the system divides the input signal in different portions, at least one of which carries information sufficient to provide intelligible reconstruction of the input signal. The analyzer also encodes separate information about other portions of the signal in an embedded manner, so that a smooth transition can be achieved from low bit-rate to high bit-rate applications. Accordingly, communication devices operating at different sampling rates and/or bit-rates can extract corresponding information from the output bit stream of the analyzer. In the present invention embedded information generally relates to separate parameters of the input signal, or to additional resolution in the transmission of original signal parameters. Non-linear techniques for enhancing the overall performance of the system are also disclosed. Also disclosed is a novel method of improving the quantization of signal parameters. In a specific embodiment the input signal is processed in two or more modes dependent on the state of the signal in a frame. When the signal is determined to be in a transition state, the encoder provides phase information about N sinusoids, which the decoder end uses to improve the quality of the output signal at low bit rates.

The method for sinusoidal audio coding includes performing sinusoidal analysis on an input signal and extracting sinusoids of a current frame; tracking and coding a continuation mode sinusoid of the current frame by using a sinusoid of a previous frame which continues to the continuation mode sinusoid; searching for a sinusoid having a closest frequency to a frequency of a birth mode sinusoid of the current frame; calculating and coding a difference between an amplitude of the sinusoid having the closest frequency and an amplitude of the birth mode sinusoid; and coding the frequency of the birth mode sinusoid.

摘要： The present technology relates to a signal processing device, method, and program that may obtain audio at a higher audio quality when decoding an audio signal.An envelope information generating unit 24 generates envelope information representing an envelope form of high frequency components of an audio signal to be encoded. A sine wave information generating unit 26 extracts a sine wave signal from the high frequency components of the audio signal, and generates a sine wave information representing an emergence start position of the sine wave signal. An encoding stream generating unit 27 multiplexes the envelope information, the sine wave information, and low frequency components of the audio signal that have been encoded, and outputs an encoding stream obtained as the result. As a result, the high frequency components included in the sine wave signal may be predicted at a higher accuracy from the envelope information and the sine wave information at the receiving side of the encoding stream. The present invention may be applied to a signal processing device.
