The Beat Calculator
The Beat Calculator is a tool for calculating the tempo of
freely recorded audio or MIDI material. It also allows you to
set the tempo by tapping.
Calculating the tempo of a recording
1. In the Project window, make a selection that covers an
exact number of beats of the recording.
2. Select “Beat Calculator…” from the Project menu.
The Beat Calculator window appears.
3. In the Beats field, enter the number of beats that the
selection encompasses.
The corresponding tempo is calculated and displayed in the BPM field.
• If you need to adjust the selection, you can go back to
the Project window, leaving the Beat Calculator open.
To re-calculate the tempo after adjusting the selection, click Refresh.
4. You can also insert the calculated tempo into the
tempo track by clicking one of the buttons in the lower left
corner of the Beat Calculator window.
Clicking “At Tempo Track Start” will adjust the first tempo curve point,
while “At Selection Start” will add a new tempo curve point at the selec
-
tion’s start position, using the “Jump” curve type (see “Adding tempo
curve points” on page 292).
Using Tap Tempo
The Tap Tempo function allows you to specify a tempo by
tapping:
1. Open the Beat Calculator.
2. If you want to tap the tempo to some recorded mate-
rial, activate playback.
3. Click the Tap Tempo button.

board or with the mouse button.
The tempo display will update the calculated tempo between each tap.
5. Click OK to close the Tap Tempo dialog.
The tapped tempo is now shown in the Beat Calculator’s BPM display.
You can insert it into the tempo track as described above.
Adjusting the audio to the project
tempo
If you want freely recorded audio to follow a fixed tempo or
a different project tempo, you can use the Set Definition
From Tempo dialog to save the tempo information from
the tempo track in the corresponding audio clips.
Proceed as follows:
1. Select the audio events that you want to have follow
the project tempo.
For example, this could be the individual tracks in a multi-track drum
session.
2. On the Audio menu, open the Advanced submenu and
select the “Set Definition From Tempo…” option.
The Set Definition From Tempo dialog opens.

If fixed tempo mode is selected when you insert the
calculated tempo, the fixed tempo will be adjusted,
regardless of which button you click.
