Play .669 files in your browser
Play .669 modules online in your browser — no desktop tracker required.
How it works
- Open Filelathe and drop your file (avoid macOS Finder Recents — use the real folder).
- A dedicated tool window opens for this format.
- Press Play when the player is ready.
Playback uses libopenmpt in an AudioWorklet inside your tab. Bytes are not uploaded to convert or stream — useful for demoscene and chiptune modules when you do not want a desktop player.
Privacy
File bytes are read in your browser for viewing and playback. Unlike upload-to-convert sites, Filelathe is built around in-tab tools. API calls may use filename, type, and small samples to choose or invent a UI.
