Exploring Efficient Waveform Diffusion Models for Foley Sound Generation
Runwu Shi, Chang Li, Jiahui Li +7
Recent advances in diffusion models have enabled high-fidelity Foley sound generation directly in the waveform space. Existing waveform diffusion models primarily rely on time-doma…
What Do Neural Networks Learn for TDOA Estimation? A Cross-Architecture Probing Study
Yaozhong Kang, Jiang Wang, Runwu Shi +3
Neural networks outperform classical GCC-PHAT for Time-Difference-of-Arrival (TDOA) estimation in noise and reverberation, yet their internal strategy remains unexplored. To uncove…
Fast-SDE: Efficient Single-Microphone Sound Source Distance Estimation in Reverberant Environments
Jiang Wang, Runwu Shi, Yaozhong Kang +3
Sound source distance estimation (SDE) is a critical capability in human-robot interaction. An inappropriate interaction distance not only reduces the reliability of speech acquisi…
Observability-Aware Active Calibration of Multi-Sensor Extrinsics for Ground Robots via Online Trajectory Optimization
Jiang Wang, Yaozhong Kang, Linya Fu +2
Accurate calibration of sensor extrinsic parameters for ground robotic systems (i.e., relative poses) is crucial for ensuring spatial alignment and achieving high-performance perce…
