Fun idea and also I didn&#x27;t know that websites could get access to my accelerometer data. However for me the sample frequency is 50 Hz which is way too low to measure even the lowest string pitch (E2, about 82 Hz).

Don&#x27;t have a handle on it, unfortunately. But the algorithm is in here: <a href="https:&#x2F;&#x2F;github.com&#x2F;tautme&#x2F;phone-sensors&#x2F;blob&#x2F;main&#x2F;guitar-tuner.html" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tautme&#x2F;phone-sensors&#x2F;blob&#x2F;main&#x2F;guitar-tun...</a>. Esp. lines 221–257 and 373–417.

Anyone got a handle on the algorithm required to do this?  I&#x27;ve got a pocketable accelerometer-enabled device I&#x27;d like to try to implement this on..

It also shows that it can leak all kinds of other information.

guitar detuner that uses accelerometer instead of microphone, it doesn&#x27;t really work, but amazing to see how sensitive they are.
