  A typical neural speech enhancement (SE) approach mainly handles speech and
noise mixtures, which is not optimal for singing voice enhancement scenarios.
Music source separation (MSS) models treat vocals and various accompaniment
components equally, which may reduce performance compared to the model that
only considers vocal enhancement. In this paper, we propose a novel multi-band
temporal-frequency neural network (MBTFNet) for singing voice enhancement,
which particularly removes background music, noise and even backing vocals from
singing recordings. MBTFNet combines inter and intra-band modeling for better
processing of full-band signals. Dual-path modeling are introduced to expand
the receptive field of the model. We propose an implicit personalized
enhancement (IPE) stage based on signal-to-noise ratio (SNR) estimation, which
further improves the performance of MBTFNet. Experiments show that our proposed
model significantly outperforms several state-of-the-art SE and MSS models.
