Testing if beats are sync
Open the Beat sync test window via the database with the "Beat sync test" button at the top left.
With the "Beat sync test" window, you can check if you placed markers on the right positions. There are 2 players: one for the intro and one for the break. The time durations of both players must be the same.
If you play the intro or break you will hear overlapping beats. You can change the volume of the overlapping beats with the slider on the top. The overlapped beats must be in sync with the beats of the song. If this is not the case,click cancel button to return to the database and check if markers are in the right place. Correct their positions where neccesary.
If the beats are in sync, click cancel to return to the database and save the record.
