I make karaoke tracks! I do not take requests, sorry.
All audio is either official instrumentals/stems or by editing the original released track. Vocal separation on the original track is done using UVR, MDX, and/or Demucs models via the UVR GUI app (github.com/Anjok07/ultimatevocalremovergui) or x-minus.pro/. Editing is done in Audacity.
Lyrics are synced at the syllable level with Karaoke Builder Studio, and initial layout and formatting are done there. Any videos since Jan 17, 2023 are then converted to Advanced Substation Alpha format, where some additional edits may be done. Background video is edited in kdenlive, then lyrics are burned in with ffmpeg.
If you want to learn more about karaoke video creation, participate in virtual karaoke events, or keep up with new releases, I strongly recommend the diveBar Discord (discord.gg/divebar). The community is very welcoming and includes a lot of people way more prolific than me in karaoke production.
