KaraokeNerds Requests Prep 🎶

Prepare for bulk karaoke video creation, by downloading audio from YouTube and lyrics from Genius for top requests on karaokenerds.

This was created with a single use case in mind - to make it easier for me to prepare for bulk creation of karaoke videos while I'm offline (e.g. on a flight or train). It makes it easy to bulk prepare the top X requests by votes, tips, views, spotify rank etc. so I can then do the actual karaoke creation in a focused batch without internet.

Features

• Audio Fetching: Automatically searches YouTube for each song, downloads the top result and extracts the best quality audio in WAV format.
• Lyrics Fetching: Automatically fetches song lyrics from Genius.com using LyricsGenius.
• Audio Separation: Separates the downloaded audio into instrumental and vocal tracks, using audio-separator.
• Multiple Audio Models: Runs audio separation with 2 different models (by default, UVR_MDXNET_KARA_2 and UVR-MDX-NET-Inst_HQ_3) to give you options for the backing track.
• Easy Configuration: Control the tool's behavior using command-line arguments.
• Organized Outputs: Creates structured output directories for easy access to generated tracks and lyrics.
• Internet First: Completes all operations which require internet first (quickly), in case user is preparing last-minute before a period of being offline!

├── Artist - Title (Instrumental UVR-MDX-NET-Inst_HQ_3).flac
├── Artist - Title (Instrumental UVR_MDXNET_KARA_2).flac
├── Artist - Title (Lyrics).txt
├── Artist - Title (Vocals UVR-MDX-NET-Inst_HQ_3).flac
├── Artist - Title (Vocals UVR_MDXNET_KARA_2).flac
└── Artist - Title (YouTube CNUgemJBLTw).wav
