Non-stationary Noise Filtering of 4K High-definition All-media Broadcasting Vehicle Audio SignalChinese Full Text
FU Dahui;Danzhou Radio and TV Station;
Abstract: The 4K audio signal noise presents a complex state and may lead to an unstable state under the impact response. Identifying and labeling the signal noise is a challenge. This paper proposes a method of non-stationary noise filtering for 4K high-definition all-media broadcasting vehicle audio signals. The amplitude frequency response feature extraction method is used to calculate the position scale parameters of non-stationary noise signals, split audio signal segments, and construct an impact re...
