Pitch Smoothing Using Relative Interval Networks
Chin-Yun Yu, Chi-Jen Peng, Li Su +1
Pitch tracking systems typically couple a per-frame fundamental frequency () estimator with a temporal smoothing stage to obtain continuous trajectories. Conventional Viterbi…
Toward Expressive Singing Voice Correction: On Perceptual Validity of Evaluation Metrics for Vocal Melody Extraction
Yin-Jyun Luo, Yuen-Jen Lin, Li Su
Singing voice correction (SVC) is an appealing application for amateur singers. Commercial products automate SVC by snapping pitch contours to equal-tempered scales, which could le…
Semi-supervised learning using teacher-student models for vocal melody extraction
Sangeun Kum, Jing-Hua Lin, Li Su +1
The lack of labeled data is a major obstacle in many music information retrieval tasks such as melody extraction, where labeling is extremely laborious or costly. Semi-supervised l…
Multi-layered Cepstrum for Instantaneous Frequency Estimation
Chin-Yun Yu, Li Su
We propose the multi-layered cepstrum (MLC) method to estimate multiple fundamental frequencies (MF0) of a signal under challenging contamination such as high-pass filter noise. Ta…
A Streamlined Encoder/Decoder Architecture for Melody Extraction
Tsung-Han Hsieh, Li Su, Yi-Hsuan Yang
Melody extraction in polyphonic musical audio is important for music signal processing. In this paper, we propose a novel streamlined encoder/decoder network that is designed for t…
Singing voice correction using canonical time warping
Yin-Jyun Luo, Ming-Tso Chen, Tai-Shih Chi +1
Expressive singing voice correction is an appealing but challenging problem. A robust time-warping algorithm which synchronizes two singing recordings can provide a promising solut…
