When things go wrong

A correct beatgraph visualization depends on a correct knowledge of the length of 1 bar. That in turn depends on a recognition of the time signature and the tempo. Although BpmDj is quite good in tempo detection, sometimes things go wrong. How this affects the beatgraphs and how it can be solved is explained below.

Tempo slightly wrong

When the tempo measurement is inaccurate, each visualized bar will pull in a bit too much or too little information in. This creates a drift that becomes larger with each consecutive bar. The result is a slanted beatgraph

Changing the angle of a beatgraph

To modify the angle of a beatgraph, open the song and then press and .

will appear in the middle of the song. Drag it up/down to modify the songs angle.

Time Signature Wrong

The time signature affects the length of a bar. E.g: a 4/4 rhythm at 120 BPM, has a bar length of 2 seconds and will show 4 beats per bar. However if the song were a 3/4 rhythm at 120 BPM, then each bar would be 1.5 seconds and only show 3 beats per bar.

If BpmDj measures the time signature wrong then it will show the wrong numbers of beats per bar, as shown in the above pictures

Modifying the time signature

To modify the time signature of a song you first need to open the song by pressing on the button. Then press on the button.

The BPM section should open with 3 buttons.

Tap this button every bar. After three or four bars the algorithm will figure out what time signature would have been most appropriate.

If you skipped a bar or felt you were inaccurate, you can press reset. This will reset the counter.

If you want to accept the shown tempo as the correct one.
