Traditional flange processing is carried out only from the time domain. The frequency characteristics of audio signals is not considered. This paper presents a new time-frequency processing scheme for flange effect, which is based on subband decomposition. An audio signal is broken down into several bands of low, middle, and high frequencies to be flanged separately. In each frequency band, the flanging parameters are selected according to the characteristics of the signal in that band. Theoretical analysis and experimental results show that the new flange processing system fits the human hearing sense and improves the effect of flange processing effectively.
