On the one hand, the "Tempo correction" list offers alternative BPM numbers
which could also fit with the music. The adjustable BPM values are detected
automatically – the total BPM can therefore deviate from song to song.
For more difficult audio material, we recommend using the "Tapping input"
mode. Either the "T" key must be pressed or the "Tap tempo" button must be
clicked with the mouse in time with the music. With repeated tapping of the
tempo correction button, one should keep an eye on the color in the BPM
display. In the "unlocked" condition (red), the tapping is not in time with the
music. One should tap until the "locked" condition is displayed. After a short
time, you will hear if the result is correct via the metronome.
Subsequently, offbeat correction takes place as required. If the detected
quarter note beats lie around the length of an eighth note (transferred behind
the real positions of the quarter note beats), one or more alternatives can be
selected from the onbeat/offbeat correction list.
Determining the start of a measure
Next, the starting point of the measure is corrected. The beat at the start of the
measure must always agree with the high tone of the metronome and/or the
red line in the wave-shaped display.
Corrections can be made by tapping; If the start of the measure can be be
heard, tap with the mouse or press the "T" key. Alternatively, you can also
select how many quarter notes the "one" is to be pushed to back.
If the starting marker was set briefly before the first beat of a measure, this
correction is not necessary.
Note: With all corrections, the metronome and visualization react to the lines in
the wave-shaped display only after a short delay.
Using BPM and beat detection
Now you may select one of the actions to be adapted to the arrangement song
(or vice versa) or cut up the songs at the ends of a measure.
Save only Tempo & Beat information
Only wave file data is stored. This makes sense if some manual post-correction
is required for determining beat/tempo.
When the data is stored, tempo & beat regulation can be released for future
tempo adjustments or to create object remixes.
