μNet: Ultra-Low-Memory and Low-Complexity Speech Enhancement for Embedded Digital Signal Processors
Shrishti Saha Shetu, Jose Miguel Martinez Aponte, Nagashree K. S. Rao +3
Speech enhancement on embedded digital signal processors (DSPs) imposes strict constraints on memory footprint, computational complexity, latency, and support for integer operation…
NDF+: Joint Neural Directional Filtering and Diffuse Sound Extraction
Weilong Huang, Le Nhat Tam Huynh, Oliver Thiergart +1
Recently, neural directional filtering (NDF) has been introduced as a flexible approach for reconstructing a virtual directional microphone (VDM) with a desired directivity pattern…
Neural Directional Filtering Using a Compact Microphone Array
Weilong Huang, Srikanth Raj Chetupalli, Mhd Modar Halimeh +2
Beamforming with desired directivity patterns using compact microphone arrays is essential in many audio applications. Directivity patterns achievable using traditional beamformers…
Sample Rate Offset Compensated Acoustic Echo Cancellation For Multi-Device Scenarios
Srikanth Korse, Oliver Thiergart, Emanuel A. P. Habets
Acoustic echo cancellation (AEC) in multi-device scenarios is a challenging problem due to sample rate offset (SRO) between devices. The SRO hinders the convergence of the AEC filt…
Low-Complexity Neural Wind Noise Reduction for Audio Recordings
Hesam Eftekhari, Srikanth Raj Chetupalli, Shrishti Saha Shetu +2
Wind noise significantly degrades the quality of outdoor audio recordings, yet remains difficult to suppress in real-time on resource-constrained devices. In this work, we propose…
A first-order DirAC-based parametric Ambisonic coder for immersive communications
Guillaume Fuchs, Florin Ghido, Dominik Weckbecker +1
Directional Audio Coding (DirAC) is a proven method for parametrically representing a 3D audio scene in B-format and is capable of reproducing it on arbitrary loudspeaker layouts.…
Neural Directional Filtering: Far-Field Directivity Control With a Small Microphone Array
Julian Wechsler, Srikanth Raj Chetupalli, Mhd Modar Halimeh +2
Capturing audio signals with specific directivity patterns is essential in speech communication. This study presents a deep neural network (DNN)-based approach to directional filte…
