How to find the tuning frequency for any song

In this demo we go over how the HZ Detect browser extension works, validate its accuracy and then test a popular "432 Hz" video that has over 57 million views but is actually tuned to 440 Hz!

We then demonstrate how it would sound if you were to really re-tune a song on YouTube from 440 Hz to 432 Hz or 528 Hz with the Music Re-Tuner browser extension.
