This is a standalone web app that displays Friday Night Funkin' charts along with audio waveforms to verify the sync of the arrows/notes to the music without any offset.

This tool is not a chart editor in its current state, just a visualizer.

• Display two audio waveforms: instrumental and voices.
• Audio playback and mixing with volume control of each track.
• Users can upload charts and music tracks.
• High DPI support for high resolution screens (experimental, useful for detailed waveforms).

This project includes all charts and music up until to Week 7 as examples.

The schema of JSON chart files are not validated. Dynamic BPM charts have not been fully tested.

Clone the project

git clone https://github.com/jsm925/FunkinChart

This is just a static web page, you can run it locally with any simple web server like Python's 'SimpleHTTPServer', node.js, nginx, etc. I mostly use a node.js static web server:

http-server -p PORT

(PORT could be any HTTP port available for development like 5000, 3000, etc.)

You might need to download this external library to open the page offline: https://github.com/bbc/waveform-data.js

This project uses up until Week 7 assets of the game, so play the game in Newgrounds!
