Document Type and Number:
Japanese Patent JP2003510665
Kind Code:
A
Abstract:
A method and apparatus for the real-time creation of an output audio signal from an input signal with an unwanted or noise portion. The system detects the unwanted portion of the input signal by utilizing an adaptive detection filter and reduces the unwanted portion of the input signal. The reduction of the unwanted portion is performed by compression of the unwanted signal, subtraction of the unwanted portion of the signal, or eliminating the output signal until the unwanted portion is no longer detected. The system is specifically designed to find a high frequency and high amplitude sound such as a sibilant.
