Audio Coding With Unified Noise Shaping And Phase Contrast Control

Byeongho Jo, Seungkwon Beack, Taejin Lee

ICASSP 2023accepted

Over the past decade, audio coding technology has seen standardization and the development of many frameworks incorporated with linear predictive coding (LPC). As LPC reduces information in the frequency domain, LP-based frequency-domain noise-shaping (FDNS) was previously proposed. To code transien…

Audio Coding Based on Spectral Recovery by Convolutional Neural Network

Seong-Hyeon Shin, Seungkwon Beack, Taejin Lee, Hochong Park

ICASSP 2019accepted

This study proposes a new method of audio coding based on spectral recovery, which can enhance the performance of transform audio coding. An encoder represents spectral information of an input in a time-frequency domain and transmits only a portion of it so that the remaining spectral information ca…
