tuner v0.0.1 (initial release)

I just released a new Chrome extension tuner, a chromatic tuner for your browser. If you like to play music, you may find this extension useful.

When I play music in Jamulus with friends, I usually need to find the key of the currently playing song. Usually I would play a random note on the instrument, and then use my relative pitch to find the key. I think there could be ways to make it more efficient. So I used the JavaScript pitch detection library pitchy and created a simple web page. Then I made it into a Chrome extension, so it can be accessed easily and is not subject to web audio’s autoplay policy.

• It shows the pitch of the incoming sound as note name (like A3 + 22 cents) and the frequency (like 444 hz).
• It graphs the pitch class heard over time, so vibrato and stuff can be visualized.
