### Finding Start/End of the Loop
|
|
|
|
|
|
The first thing you'll need is a music file that you want to loop. It should contain the intro and two full loops of the song.
|
|
|
|
|
|
Launch Audacity and open your music file.
|
|
|
>>>
|
|
|
**Note:** This tutorial will use a mono (single track) song as an example for the sake of simplicity, but the same steps could be applied to a stereo song that contains separate tracks for the left and right channels.
|
|
|
>>>
|
|
|
|
|
|
Launch Audacity and open your music file as shown in Figure 1.

The first thing you'll want to do is to look for a distinctive shape in the waveform that occurs during the loop (so you'll see it appear twice in the waveform display). In the example shown, one such distinctive pattern is marked with red arrows.
|
|
|
|
|
|
Place a marker approximately at this same location in both the first loop and the second loop (they don't have to be exact, there will be further adjustment later). Zoom in to where you want to place the marker and from the menu select:
|
|
|
|
|
|
```
|
|
|
Edit > Labels > Add Label at Selection
|
|
|
```
|
|
|
|
|
|
Figure 2 shows the placement of the first marker. You can give it a name if you like.

And a second marker is placed at approximately the same location in the second loop, as shown in Figure 3.

Zooming out to see the full waveform, both markers can be seen in Figure 4.

|
Next you'll want to select the portion of the song between the two markers. Do this by clicking in track 1 at the location of one of the markers and drag to the location of the other marker. Write down the number of samples in the selection as shown at the red circle in Figure 5.

|
The next step is to add a new blank track by selecting the following from the menu:
|
|
|
|
|
|
```
|
|
|
Tracks > Add New > Mono Track
|
|
|
```
|
|
|
|
|
|
Now you want to select the beginning of the new track. Do this by clicking somewhere in the new (blank) track and dragging as far as you can to the left as shown in Figure 6. If done correctly, then the start of the selection at the bottom of the window should read "000,000,000 samples".
