A significant portion of the game's modding culture involves "Full Week" creations featuring licensed or sampled music. To comply with copyright or to create custom gameplay experiences (specifically "Mania" style modes), modders require instrumental versions of tracks. This paper explores the application of AI-driven vocal removal techniques—specifically Spleeter and Demucs—within the FNF ecosystem, analyzing the technical constraints of source separation on compressed game audio and the workflow integration for rhythm game charting.

Producers can take the isolated vocals and completely rebuild the instrumental backing track in a different musical genre, such as Lo-Fi, Metal, or Synthwave.

Modern vocal removal in the FNF community relies on Deep Learning models rather than traditional frequency filtering (panning cancellation).
