NNSVS: DNN-based singing voice synthesis samples

https://github.com/r9y9/nnsvs/issues/76

Implemented pitch regularization loss. It seems that the pitch gets very stable.

Same model architecture as https://soundcloud.com/r9y9/20220309-nit-song070-svs-world-conv-sine-based-vibrato-modeling-skip-connection-nitech-jp-song070-f001-003 but with an additional pitch regularization loss.

TEAM AUXILIARYの新しいプロジェクト「SEVEN(No7) for NNSVS/ENUNU」を発表！
経験を積むための研究プロジェクトで能力を見させてくだらい！
プレアルファ版ですが、高機能があります。
今はまだ調査中から完成品をお待ちください！

TEAM AUXILIARY is proud to present our first project: SEVEN(No7) for NNSVS/ENUNU!
This is an independent research project to gain experience and to show we can do!
The current model is a pre-pre-alpha but we believe the program has strong capabilities.
We are excited to do more research and can't wait to share the finished result with everyone!

GAN-based post-filter ありバージョンです。過剰平滑化問題が緩和されて、クリアになっていま（一方、現状、若干ノイズっぽくなってしまいます。気になる？

てるみい、の最後のサビの部分だけ。てるみい最高

開発中のモデルです。以前よりもビブラートがきれいに出ているはず？
無調声、NNSVS の raw output です。IA＆OИE の2パート、どちらも波音リツです

2022/08/02 NNSVS Ritsu Test Tellme

This demo shows the strong capability of the autoregressive F0 model. 

NOTE:
- Namine Ritsu's database [1] is used to train a backbone model.
- NIT-song 070 database is used for fine-tuning
- WORLD vocoder is used instead of a neural vocoder (to save my time to train a vocoder)
- Sampling rate: 48kHz

ルカルカ★ナイトフィーバーのカラオケ音源です。
オリジナル音源だと大手を振っての使用はしづらいかなと思い、作成に至りました。
良かったら歌ってくださいね！

i made karaoke of LUKALUKA★NIGHTFEVER.

i uploaded same track for youtube.
that's subed with romaji.
hope you sing and enjoy^^
