Audio Tools
Free browser-based audio tools for producers and DJs — a chord and scale lab with MIDI export, batch sample prep, BPM maths, a tuner and metronome, a lo-fi effects processor, ear training and a track analyser for LUFS, key and BPM. No account, no upload, no server ever hears your audio. The full workstation lives at /studio; these are the tools around it.

FAQ
Are these audio tools free?
Yes — every tool here is free and unlimited. Pro only adds MP3 and stem export in Studio and batch/format extras noted on individual tool pages.
Is my audio uploaded anywhere?
No — every tool decodes and processes audio entirely in your browser; nothing is sent to a server.
What's the difference between these tools and Studio?
These are focused single-purpose tools. Studio is the full workstation — drum machine, synth, mixer and export — that they sit around.
Do I need an account?
No — no sign-up, no account. Open a tool and start using it.
