    Default How do software's calculate the BPM of tracks that 'have no beats' ?

    So i have a track (above) which has no beats at all throughout the song. But my Rekordbox shows 144.42 BPM.
    Was curious to know how and why it shows so.

    Lol you're asking why rekordbox does its job. The track has to have a BPM even if it doesn't have beats unless it's just random synths and ambient noises.

    So it randomly categorizes these sounds as beats.

    But Isn't it inappropriate to call a beat less track a 144 BPM track or whatever.

    what about acapellas? on tracks with only vocals. those have beatgrids and dont have beats. you are thinking to hard about this. its very strange these days that anyone would have song of random sounds and synths. i garuntee that track has a bpm. will you post the track here?

    Lack of beats =/= lack of tempo

    The most common method is to analyze transients in the audio. Normally this lines up with the beats if a tracks has them which makes analysis easier. Unless it's a one shot sound, all samples, acapellas, etc have a static or varying BPM they were recorded at (regardless of wanting to record at a specific BPM or not).

    A clear example of this, most people recording an acapella do it along a metronome (so they follow the metronome's BPM)
