You can edit your recording by cutting out sections of unwanted audio.
To do this:
1. Tap 'Button 1' (see the screenshot below) to show the yellow region selection.
2. Use the two yellow markers to select the area of the recording you want to delete.
3. Tap 'Button 2' to delete the selected area from your recording. You can play the recording and listen to your edit to ensure it is correct.
4. Repeat steps 2-3 to remove all unwanted areas from the recording.
At this point, your edits have not yet been saved and you can revert to your original recording by tapping the Cancel button.
If you are happy with your edits, tap the Save button to overwrite the original file with the new version.
