Lo-fi BPM

What tempo is lo-fi hip-hop? 60 to 80 BPM where Soundtrap and ModeAudio overlap, with a swung, lazy groove, a tap counter and the delay and LFO values.

Mika sleeps through lo-fi. That is what it is for, he says.Play the groove at this tempo, or tap the pad along with a track to check its tempo against the range.

Lo-fi hip-hop: 60–80 BPM

How fast, and who says so

Where the two sources overlap: 60–80 BPM. Each in its own words:

The groove on this page

Lo-fi hip-hop is boom-bap slowed down and loosened: a kick on the one and the and of three, a soft snare on two and four, quiet hats, few elements, often only three. Soundtrap's guide sets swing between 50 and 60 % and Native Instruments drags every second hat late by hand, so nothing sits quite on the grid. The tempo is slow enough to feel like a half-time beat at its slowest.

On this page: the app's Soft kit at 76 BPM, swing 60 %.

Delay and LFO values

A delay in time with the track repeats once per note value: a quarter note lasts 60,000 divided by the BPM, in milliseconds. Dotted is one and a half times that, triplet two thirds. An LFO synced to a note value cycles at 1,000 divided by those milliseconds, in Hz. The table follows the tempo above: − and + move it, and so does a tempo you tap.

Then make something of it

The door opens Brumm, a club track with a beat and a bass, with this groove's low end in it. The app runs between 90 and 150 BPM, so a faster or slower tempo goes in at half or double. No account, no upload: it travels inside the link. Hum a line over it, and it becomes an instrument.

Nothing is recorded: no microphone, only your taps, counted in the browser. The groove's sounds are the app's own samples, fetched when you tap Play. How the site counts visits.

Audio: tones your browser makes on this page; no microphone. Nothing about the audio reaches the visit count.
