In a sound processing method of operating audio equipment to perform sound processing relating to audio content in accordance with one embodiment, a distributor terminal communicates with the audio equipment and at least one listener terminal, the distributor terminal distributes the audio content from the distributor terminal to the at least one listener terminal, the distributor terminal specifies an operation listener terminal, from among the at least one listener terminal, that is permitted to change a sound processing parameter of the audio equipment, the operation listener terminal accepts the sound processing parameter changed by the operation listener terminal, the operation listener terminal transmits the sound processing parameter changed by the operation listener terminal to the distributor terminal, and the audio equipment performs the sound processing based on the changed sound processing parameter changed by the operation listener terminal.

Sound processing method, terminal, and sound system

A management method includes generating frequency information indicative of a frequency band of radio waves available to a first audio system from among a plurality of audio systems, by reference to radio wave information indicative of a frequency band of radio waves used by a second audio system, other than the first audio system, from among the plurality of audio systems, where each audio system includes one or more receiving devices for wireless reception of an audio signal; and transmitting the generated frequency information to the first audio system.

Management method, management apparatus, and information processing apparatus

To a first analog signal that has been inputted, a first channel effect is added by an analog process that can be controlled with controls provided in a first channel strip. To a second analog signal that has been inputted, a second channel effect is added by a digital process, the second channel effect being controlled by a fourth control provided in a second channel strip. The second channel effect is preferably performed by a digital effect DSP.

Analog mixer apparatus

When a knob is at a center position, transmission levels of first volumes on a path from a second effector to a first effector, and second volumes on a path from the first effector to the second effector are both zero, and the first effector and the second effector operate independently. When the knob is displaced to right side from the center position, the transmission level of the second volumes is controlled according to the displacement amount, but the transmission level of the first volumes stays at zero. Thus, the second effector is connected in series to the first effector. When the knob is displaced to left side from the center position, the transmission level of the first volumes is controlled according to the displacement amount, but the transmission level of the second volumes stays at zero. Thus, the first effector is connected in series to the second effector.

Effect applying apparatus and effect applying method

An acoustic controller includes a housing including: an upper cover; a lower casing constituted by a shielding member; and a lower cover mounted on an opposite side of the lower casing from the upper cover. The lower casing partitions an interior of the housing into (i) an upper space formed by the upper cover and the lower casing and (ii) a lower space formed by the lower casing and the lower cover. A first circuit board is disposed in the upper space, and a second circuit board is disposed in the lower space.

Acoustic controller

An acoustic signal's high frequency component extracted by an HPFis multiplied in a multiplierby the first coefficient to control the level of the high frequency component. The first coefficient is generated by a coefficient generation portionin accordance with the full band level of an output signal. A low frequency component extracted by an LPFis multiplied in a multiplierby the second coefficient to control the level of the low frequency component. The second coefficient is generated by a coefficient generation portionin accordance with the level of the output signal's low frequency component extracted by an LP filter. The level control of the low frequency component of the output signal and the level control of the high frequency component of the output signal are done separately, resulting in the loudness control which is suitable for the characteristic of the acoustic signal.
