On the Invariance of Cross-Correlation Peak Positions Under Monotonic Signal Transformations, with Application to Fast Time Difference Estimation
Natsuki Ueno, Ryotaro Sato, Nobutaka Ono
We present a theorem concerning the invariance of cross-correlation peak positions. This theoretical result provides the foundation for a new method for time difference estimation…
Incremental Averaging Method to Improve Graph-Based Time-Difference-of-Arrival Estimation
Klaus Brümann, Kouei Yamaoka, Nobutaka Ono +1
Estimating the position of a speech source based on time-differences-of-arrival (TDOAs) is often adversely affected by background noise and reverberation. A popular method to estim…
Description and Discussion on DCASE 2025 Challenge Task 4: Spatial Semantic Segmentation of Sound Scenes
Masahiro Yasuda, Binh Thien Nguyen, Noboru Harada +10
Spatial Semantic Segmentation of Sound Scenes (S5) aims to enhance technologies for sound event detection and separation from multi-channel input signals that mix multiple sound ev…
Mel-Spectrogram Inversion via Alternating Direction Method of Multipliers
Yoshiki Masuyama, Natsuki Ueno, Nobutaka Ono
Signal reconstruction from its mel-spectrogram is known as mel-spectrogram inversion and has many applications, including speech and foley sound synthesis. In this paper, we propos…
