Patent number: 7986797Abstract: A signal processing system, a signal processing apparatus and method, a recording medium, and a program in which high frequency components of a narrow-range signal having suppressed high frequency components can be restored with high accuracy. A narrow-range audio signal having low frequency components is divided into frames by a frame-unit dividing unit, and is spectral-transformed into a signal on a frequency domain by a DCT transform unit. A learning-produced-data table extracts, at an address corresponding to a class code supplied from a classifying unit, high-frequency-component DCT spectrum data. In a spectrum combining unit, the extracted high-frequency-component DCT spectrum data is combined with low-frequency-component DCT spectrum data output from the DCT transform unit. Subsequently, a broad-range audio signal having combined high frequency components and low frequency components is output.Type: GrantFiled: October 1, 2009Date of Patent: July 26, 2011Assignee: Sony CorporationInventors: Tetsujiro Kondo, Masaaki Hattori, Tsutomu Watanabe, Hiroto Kimura, Sakon Yamamoto, Akihiko Arimitsu

Publication number: 20100198426Abstract: A partition, a control device and method, a program, and a recording medium that can enhance the acoustic effect. Partitions are set in a room beforehand. The partitions are movable along a guide provided in a ceiling. In the room, furniture and a speaker are set. When sound from the speaker is reflected by the furniture and the reflected sound is given to a user, the acoustic effect is lessened. Accordingly, the partitions are moved in front of the furniture. Further, the partitions are moved so as to be symmetrically arranged with respect to the speaker. The movement of the partitions can produce an acoustic space in which the reflected sound is uniform. The present invention is applicable to a partition that enhances the acoustic effect.Type: ApplicationFiled: August 8, 2008Publication date: August 5, 2010Applicant: Sony CorporationInventors: Tetsujiro Kondo, Junichi Shima, Akihiko Arimitsu, Takuro Ema

Patent number: 7555429Abstract: Speech likeliness or a degree of speech is determined with a simple configuration or with a small amount of processing, and speech parts are separated from an input sound signal. The input sound signal is subjected to a waveform slicing process in frame units. The increase and decrease rate of a half wavelength in the frame is computed. The rate of a zero cross in the frame is computed. The increase and decrease rate of a half wavelength is computed by determining the rate of the portion where the upward half-wavelength or the downward half-wavelength of the waveform of the input sound signal changes to increase and decrease alternately or to decrease and increase alternately. The degree of speech is determined using each rate. Speech processing for separating or accentuating/attenuating speech and background noise in accordance with the degree of speech is performed on the sound signal for each frame.Type: GrantFiled: June 30, 2005Date of Patent: June 30, 2009Assignee: Sony CorporationInventors: Tetsujiro Kondo, Junichi Shima, Hiroshi Ichiki, Akihiko Arimitsu
