Abstract: An audio signal-processing system has signal-processing units connectable to a transmission line. Each signal-processing unit has channels for applying a signal process to input audio signals. A control unit is connectable to the transmission line for operating a target channel belonging to one of the signal-processing units. The control unit has color pallets different from each other and previously selected in correspondence to the signal-processing units. When the control unit detects an instruction to display an operation screen of the target channel, the control unit renders the operation screen of the target channel using the color pallet corresponding to the signal-processing unit to which the target channel belongs, so that a background color of the operation screen of the target channel displayed on a display part of the control unit is different from a background color of an operation screen of another channel belonging to another signal-processing unit.

Abstract: In a music selection mode, a reproduction object deciding unit in an audio reproducing apparatus selects a plurality of pieces of candidate music from music data stored in a storage unit and has a reproducing unit reproduce them simultaneously. An assigned position deciding unit controls an audio processing unit in such a manner as to assign the sound images of the pieces of candidate music respectively to different positions. An input by which one unit of sound is selected from among a plurality of sounds that a user hears from the different positions is entered to an input unit. Then the reproduction object deciding unit determines that music data corresponding to the sound has been selected. This causes a changeover to a normal mode and the selected music data only is reproduced.

Abstract: In an acoustic design support apparatus, a speaker selection supporter selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space.

Abstract: A method and system for performing audio signal processing is provided. A phase of a signal may be shifted between 0° and 360° for all frequencies of the signal, without any significant delay distortion. The phase shift can be accomplished through the use of two signal outputs (which are each shifted in phase by 90° relative to the other), inverters and an analog summing circuit. Selective use of the inverter on one or both of the 90° phase shifted outputs, and their linear combinations, allows the phase of the audio signal outputs to be shifted between about 0° and about 360° by a recording engineer, for example.

Abstract: A sound receiver includes a casing having multiple cavities which house multiple microphones and through which sound waves are received. A first sound wave is directly received by microphones. A second sound wave is reflected by an inner wall of the cavities and changes in phase corresponding to the material of the inner wall. The material of the inner wall differs for each cavity, thereby effecting a different change in phase of the second sound wave at each of the inner walls.

Abstract: Systems and methods for monitoring a sound pressure level dose at an ear are provided. A system includes an audio transducer which outputs a sound signal is placed within an ear to receive sound at the ear. A sound level threshold detector determines whether a sound pressure level of the sound signal is at a minimum level and outputs a sound pressure level signal corresponding to the sound pressure level when the sound pressure level is not at the minimum level. A time period is calculated during which the sound pressure level is not at the minimum threshold level. A listening fatigue calculator determines whether a cumulative effect of exposure to the sound signal at the ear over the time period will cause harm to the ear. At least a portion of the system is disposed in situ at the ear.
