Sampling-Frequency-Independent Universal Sound Separation
Tomohiko Nakamura, Kohei Yatabe
This paper proposes a universal sound separation (USS) method capable of handling untrained sampling frequencies (SFs). The USS aims at separating arbitrary sources of different ty…
Simultaneous Measurement of Multiple Acoustic Attributes Using Structured Periodic Test Signals Including Music and Other Sound Materials
Hideki Kawahara, Kohei Yatabe, Ken-Ichi Sakakibara +2
We introduce a general framework for measuring acoustic properties such as liner time-invariant (LTI) response, signal-dependent time-invariant (SDTI) component, and random and tim…
Versatile Time-Frequency Representations Realized by Convex Penalty on Magnitude Spectrogram
Keidai Arai, Koki Yamada, Kohei Yatabe
Sparse time-frequency (T-F) representations have been an important research topic for more than several decades. Among them, optimization-based methods (in particular, extensions o…
LibriTTS-R: A Restored Multi-Speaker Text-to-Speech Corpus
Yuma Koizumi, Heiga Zen, Shigeki Karita +7
This paper introduces a new speech dataset called ``LibriTTS-R'' designed for text-to-speech (TTS) use. It is derived by applying speech restoration to the LibriTTS corpus, which c…
Safeguarding test signals for acoustic measurement using arbitrary sounds
Hideki Kawahara, Kohei Yatabe
We propose a simple method to measure acoustic responses using any sounds by converting them suitable for measurement. This method enables us to use music pieces for measuring acou…
Design of Tight Minimum-Sidelobe Windows by Riemannian Newton's Method
Daichi Kitahara, Kohei Yatabe
The short-time Fourier transform (STFT), or the discrete Gabor transform (DGT), has been extensively used in signal analysis and processing. Their properties are characterized by a…
