摘要： 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.

摘要： In a sound-source signal separating method, a target sound-source signal in an input audio signal is enhanced, the input audio signal being from a mixture of acoustic signals from a plurality of sound sources picked up by a plurality of sound pickup devices. The pitch of the target sound-source signal in the input audio signal is detected, and the target sound-source signal is separated from the input audio signal based on the detected pitch and the enhanced sound-source signal.

摘要： There is a need for being able to excellently audiovisually receive contents without disordering a room atmosphere. An audiovisual room 1 is provided with one wall including an inner wall 2 and an outer wall 3. Part or all of the innerwall 2 forms a rear-projection screen 6C or a diaphragm (speaker unit) 6A. Equipment such as a projector 10 and an amplifier is placed in a space between the inner wall 2 and the outer wall 3. The space is large enough for a person to enter. Accordingly, a serviceperson etc. can enter the space to easily do works such as maintaining the equipment. The equipment such as the projector is not placed in the audiovisual room 1, making it possible to audiovisually receive contents without disordering a room atmosphere.

摘要： 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.

摘要： An audio output apparatus is provided. The audio output apparatus includes: a vibration member, a vibrator, a vibrator positioning unit, and a vibrator-depth positioning unit. The vibration member vibrates to output a sound. The vibrator is in contact with the vibration member and detachably attached thereto to allow the vibration member to vibrate in response to an input audio signal. The vibrator positioning unit controls a contact position between the vibrator and the vibration member. The vibrator-depth positioning unit adjusts a position of the vibrator in the direction of being pressed against the vibration member and brought into contact with the vibration member.
