Tap Tempo: the BPM of a song playing now
Use Tap Tempo when the music is coming from anywhere you can hear it: a streaming app, the radio, vinyl or a live band. It needs no file. Tap on every beat, ideally on the kick or snare drum. A first reading appears after your second tap, and 16 to 32 taps usually give a steady one to within half a BPM.
When you have a tempo, open the metronome check and play a click over the song. If the click drifts ahead or behind, nudge it until it locks. Tap Tempo also converts the BPM into delay times in milliseconds for a delay pedal, and shows the quarter-note tempo for songs in 6/8 that a DAW expects.
BPM Finder: the tempo of a song file
Use the BPM Finder when you have the song as a file: an MP3 you bought, a WAV from your DAW or a voice memo. Drop it on the page and it measures the tempo in a few seconds, with a confidence rating and the half- and double-time readings. It can’t look songs up by name or open Spotify or YouTube links, and files can be up to 10 minutes long. A click track and a tap pad let you check the result by ear.
MP3 Cutter: keep the part you want
Use the MP3 Cutter to trim the silence off a voice memo, keep the chorus of a song or cut a mistake out of the middle of a recording. Drag the handles on the waveform or type exact times, add fades, and save as MP3 or WAV. Files up to 15 minutes open on a computer, 10 on a phone, because the browser holds the whole song in memory while you edit.
Ringtone Maker: your song as a ringtone
Use the Ringtone Maker to turn a song into a ringtone. Drag the 30-second window to the part you want, or let it find the loudest part, which is often the chorus. It saves an M4R file for an iPhone or an MP3 for Android, with a short fade so the ringtone loops smoothly, and shows the steps to set it on your phone.
Getting a BPM you can trust
Tap where the beat is strongest, and don’t stop for fills. If the number looks twice too high, you probably tapped eighth notes: press ÷2. If it’s half what you expected, press ×2. DJs who beatmatch can turn on two decimals in Settings, and live music that speeds up is easier to follow with the Recent number, which uses only your last few taps. Each result goes into a list for the tab, so you can measure a whole playlist and copy it at the end.
Tune before you play: the online tuner names any note, and the ukulele tuner, violin tuner and bass tuner know your instrument’s strings. The tone generator plays a steady A4 = 440 Hz or any other pitch to tune or sing against. To hear how you sound, record a practice take with the online voice recorder: it stays on your device until you download it.
