Abstract:In this paper, a new dynamic noise reduction algorithm is proposed based on time-variety filter (TVF), which can be implemented in both time and modified discrete cosine transform (MDCT) domain. In time domain, an IIR filter with changeable bandwidth is for the TVF. In frequency domain, combined with MDCT transform, the noise is suppressed in MDCT domain. A few experiment results reveal that the algorithm retains the noise-suppressing performance with low delay and algorithm complexity. ? 2011 IEEE.
