Creating loops in Edit View
Select a range for a loop
To create a good loop from an existing file, you first need to select a range that repeats precisely on a beat. Repeating
on a beat lets you combine a loop in rhythm with other loops.
1 In Edit View, open a file from which you want to create a loop.
2 Choose Edit > Auto-Mark > Find Beats And Mark. Then specify the Decibel Rise and Rise Time for beats, and
click OK.
3 Choose Edit > Snapping > Snap To Zero Crossings.
This command makes your selection snap to places in the waveform that have zero amplitude, preventing audible
noise at the beginning and end of the loop.
4 Select the range that you want to become a loop, typically starting and ending on a beat.
For guidance, use the beats you marked in step 2, together with commands in the Edit > Find Beats menu. (See
“Select audio between beats” on page 75.)
Selecting a range that starts and ends on a clear beat helps create a good loop.
5 Click the Play Looped button to repeatedly play your selection.
6 Adjust the start and end of the selection to fine-tune the loop.
7 Choose View > Display Time Format > Edit Tempo to calculate the tempo of the selected range, and then
click OK.
8 Choose Edit > Copy To New.
9 In the new file, choose File > File Info, click the Loop Info tab, and set original loop properties.
To create a loop that repeats seamlessly, see “View the top and tail of an audio file” on page 71.
