Questions
How accurate is this tuner?
In a quiet room with a clean tone, the reading is usually within a few cents. Background noise, an amp buzz or a loud room lower the accuracy. For critical tuning, check against a reference tone.
What does A4 = 440 Hz mean?
A4 is the reference pitch that every other note is measured from. Most music is tuned to 440 Hz, but some orchestras and older instruments use a slightly different value, so the setting here can be changed from 430 to 450 Hz.
What is standard guitar tuning?
From the thickest string to the thinnest: E2, A2, D3, G3, B3, E4. Drop D lowers only the thickest string from E2 to D2.
Does the tuner send my audio anywhere?
No. The microphone signal is analysed in this page and nothing is recorded or uploaded. The microphone stops when you press Stop or leave the page.
