FAF-Filt: Frequency-aware Fourier Filter for Sound Event Detection

Siyu Sun, Xiaohuai Le, Zhuangqi Chen, Xianjun Xia, Chuanzeng Huang

ICASSP 2025accepted

Capturing time-frequency patterns along the frequency axis, is crucial for the precision of sound event detection systems. Frequency dynamic convolution (FDY) and a series of its variants which incorporate frequency-adaptive kernels in standard 2D convolutions, have demonstrated remarkable performan…

A Progressive Neural Network for Acoustic Echo Cancellation

Zhuangqi Chen, Xianjun Xia, Siyu Sun, Ziqian Wang, Cheng Chen, Guoliang Xie +2

ICASSP 2023accepted

Acoustic echo cancellation is a key issue in hand-free communication systems. In this paper, we proposed a hybrid signal processing and deep echo cancellation method, where a two-stage neural network is designed to remove residual echo progressively. For the personalized acoustic echo cancellation,…
