Audio Analyzer
Drop a track and Skeletune reads its key, tempo, length, loudness and format at once, then hands the same decoded file to any tool without analysing it twice.
Key—Detected tonic, mode and Camelot code
BPM—Tempo from the onset envelope
Length—Duration of the decoded file
Loudness—Integrated loudness, EBU R128

Privacy plate
Audio files stay on the machine in front of you. The interface is designed around local browser tools, with no uploads, no account requirement and no server-side audio pipeline in this kit.
The specimen-plate layout keeps the tool first and the pitch second: load a track, read the result, then scroll only if you want background notes about the atlas.
Against the usual audio web app
- Typical
- Dark panels, neon meters, upload-first workflows
- Skeletune
- Paper plates, ink traces, local-first tools
