Free BPM and Key Finder by MusicWave

Description

Find the BPM and key of whatever is playing in your browser tab. Free, no account, and the audio stays on your device. Find the tempo and key of a song playing in your browser, without downloading or uploading anything. Click the icon while music plays in a tab. The first numbers appear in about 10 seconds, and the BPM shows right on the icon. It keeps listening for up to a minute to firm up the result, even if you close the window. WHAT YOU GET • BPM, with the half-time and double-time numbers • Key, such as F♯ minor • Camelot code for mixing, such as 11A • A confidence rating based on how much of the song it heard • One click to make a new track in that key and BPM on MusicWave NO ACCOUNT, NO UPLOADS The audio is analyzed on your own device, using the same analyzer as MusicWave's free online BPM and key finder. It is never recorded, saved or sent anywhere. The extension only listens to the tab you click on, and only after you click. GOOD TO KNOW • Works on YouTube and other sites that play audio in the tab. • It's most accurate once a song is past its intro. If a key looks off, press Listen again later in the song. • The first time you use it, your browser asks for permission to capture tab audio. Browsers show a general warning about data on websites for this permission. It's used only to hear the tab you clicked on. • Prefer to use a file?
