rzzzzru: I've been working on a karaoke app called Nightingale. You point it at your music folder and it turns your songs into karaoke - separates vocals from instrumentals, generates word-level synced lyrics, and lets you sing with highlighted lyrics and pitch scoring. Works with video files too.Everything runs locally on your machine, nothing gets uploaded. No accounts, no subscriptions, no telemetry.It ships as a single binary for Linux, macOS, and Windows. On first launch it sets up its own isolated Python environment and downloads the ML models it needs - no manual installation of dependencies required.My two biggest drivers for the creation of this were: The lack of karaoke coverage for niche, avant-garde, and local tracks. Nostalgia for the good old cheesy karaoke backgrounds with flowing rivers, city panoramas, etc. Some highlights: Stem separation using the UVR Karaoke model (preserves backing vocals) or Demucs Automatic lyrics via WhisperX transcription, or fetched from LRCLIB when available Pitch scoring with player profiles and scoreboards Gamepad support and TV-friendly UI scaling for party setups GPU acceleration on NVIDIA (CUDA) and Apple Silicon (CoreML/MPS) Built with Rust and the Bevy engine The whole stack is open source. No premium tier, no "open core" - just the app.Feedback and contributions welcome.
antihero: This looks like awesome awesome fun! Will let you know how it runs. What a wonderful idea <3
rjh29: I think you nailed it. Does it support pitch/tempo controls?
10729287: Open source, local and passion driven. The kind of news that make me believes in humanity again. Thank you, can't wait to try it this week-end !
solstice: Excited to try this out. How well does WhisperX deal with lyrics in say Mandarin or Cantonese? Does it output Hanzi?
integralid: >app that works with any song on your computerImpressive, very nice. Now let's see my death metal collection.Just joking! Very nice, thanks for open-sourcing it.
whilenot-dev: Just tried it with B.E.D - Walk Away[0], unfortunately it lost track of the lyrics after 30 secs (Model is "large-v3"). Will play around a bit more, as it would be great to have a working karaoke generator.Some quick feedback: - Needs a way to skip for-/backwards during playback to validate the result - Sentences seem to be recognized (first letter has uppercasing), but periods aren't added - Needs an option to edit results from the track analysis Thanks for keeping it FOSS![0]: https://www.youtube.com/watch?v=_MFT4H3VoNE
defrost: Struggled somewhat with Tjamuku Ngurra by the Tjintu Desert Band, absolutely nailed Mariah Carey's Ken Lee.
ETlol: VirusTotal says the .EXE is flagged by 1 security vendor but threat is low
