About this tool

Music Practice Kit combines everyday instrument-practice utilities into one mobile-friendly browser app: tuner, metronome, tap BPM, drone tone, and practice timer can be used from the same interface.

It also includes microphone recording and a real-time frequency spectrum. Audio used by the tuner, recorder, and spectrum view is processed in the browser and is not uploaded to Browser Kitty.

Frequently asked questions

Is microphone audio uploaded?

No. Pitch analysis, spectrum processing, and recording run in the browser. Recordings remain in device memory until you explicitly save them.

Can I use it without microphone access?

Yes. Metronome, Tap BPM, drone tones, and the practice timer work without microphone permission.

Can I tune instruments other than guitar?

Yes. Along with Chromatic mode, presets are provided for guitar, high-G ukulele, and four-string bass.

Can I save a recording?

Yes. You can play it back in the page and then save the recording file produced by the browser.

Offline version and source code

GitHub provides a self-contained single-HTML build. Features such as the metronome work locally, but some browsers block microphone access from file://, in which case use the HTTPS version.
