n 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.
