chartgen turns songs into Clone Hero charts

chartgen.org Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

An open-source Windows tool that converts YouTube links or local audio files into playable Clone Hero song folders.

Landing page captured for the 2026-09-13 issue.

Field notes

The workflow accepts either online sources or local audio, then writes a complete song folder for Clone Hero rather than stopping at raw note transcription. The page specifies six-way stem separation, four difficulty tiers, synced lyrics sourced from LRCLIB when available, and a local-processing model. Installation is unusually concrete: Windows 10/11, an approximately 3 GB dependency download, another 2.5 GB of models, and an NVIDIA GPU recommendation.
