  • Method for eliminating musical tone from becoming wind shear sound
    Patent number: 7171245
    Abstract: The present invention provides a method for eliminating a musical tone from becoming a wind shear sound, which is used for the music recording file played in the GSM mobile communication system, such as the personal ring back tone. The method is to judge a portion of the music recording file where the music tone is erroneously judged as a background music, and add a small section of silence in front of the portion, so that the GSM mobile communication system would not judge the portion of the music tone as the background music so as to effectively eliminate the generation of the wind shear sound.
