Abstract
An automatic sound field correcting device applies signal processing onto audio signals of plural channels and outputs processed audio signals to corresponding plural speakers. The automatic sound field correcting device includes: a noise measuring unit for measuring environmental noise level; a signal level determining unit for determining a measurement signal level based on the environmental noise level; and a correcting unit for outputting a measurement signal having the determined measurement signal level to perform automatic sound field correction.
Claims10
An automatic sound field correcting device for applying signal processing onto audio signals of plural channels and outputting processed audio signals to corresponding plural speakers, comprising:
- a noise measuring unit for measuring environmental noise level;
- a signal level determining unit for determining a measurement signal level based on the environmental noise level;
- and
- a correcting unit for outputting a measurement signal having the determined measurement signal level to perform automatic sound field correction.
A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to control the computer to function as an automatic sound field correcting device for applying signal processing onto audio signals of plural channels and outputting processed audio signals to corresponding plural speakers, comprising:
- a noise measuring unit for measuring environmental noise level;
- a signal level determining unit for determining a measurement signal level based on the environmental noise level;
- and
- a correcting unit for outputting a measurement signal having the determined measurement signal level to perform automatic sound field correction.
A computer data signal embodied in a carrier wave and representing a series of instructions which cause a computer to function as an automatic sound field correcting device for applying signal processing onto audio signals of plural channels and outputting processed audio signals to corresponding plural speakers, comprising:
- a noise measuring unit for measuring environmental noise level;
- a signal level determining unit for determining a measurement signal level based on the environmental noise level;
- and
- a correcting unit for outputting a measurement signal having the determined measurement signal level to perform automatic sound field correction.
