Signal encoding and signal decoding apparatus

TL;DR: In this paper, a circuit for determining the block length of the input audio signals based upon detected values of predetermined portions of input signal and then performing an orthogonal conversion of the determined block length signal, in which the signal is orthogonally transformed from a timedomain signal to a frequency-domain signal.
Patent

Information detection apparatus and method, and information search apparatus and method

TL;DR: In this article, an LSP decoding section extracts and decodes only LSP information from coded speech data, which is read for each block, and a Cepstrum conversion section converts the obtained LPC information into an LPC CepStrum which represents features of speech.
Patent

Sensor, sensor signal processor, and power line signal encoder

TL;DR: In this article, the amplitude and phase of a fundamental wave which are estimated from the output signal from the sensor and encoded with a value for the fundamental wave are relativized.
Patent

Speech encoding method and apparatus, and sound signal encoding method and apparatus

TL;DR: In this article, a perceptually weighted vector quantization method was proposed to reduce the processing volume in calculating a weight value for perceptually-weighted quantization, which can be used to speed up the processing or to relieve the load on hardware.
PatentDOI

Acoustic signal processing apparatus and method, signal recording apparatus and method and program

TL;DR: In this article, a feature extraction unit extracts sound quality featuring quantities, relevant to the sound quality, from the acoustic signals, to quantify sound quality peculiar to a climax, in order to detect a true highlight domain, based on the so calculated score value.
