You can edit your audio by wiping out any useless clips, either while recording, or in post-production.
While recording, you can pause at any time and edit what you’ve recorded.
For post-production, you can enter the My Recording page. Tap the three dots next to the file then select Edit.
Follow the below images to edit your recording.
1. Move the Start line and End line. Select the segment you want to delete.
Tap Play if you want to listen to the selected part.
2. Tap Cut out then the selected segment will be deleted.
3. When you finish editing, tap Save. Or if you don’t want to save the edits, just tap the arrow icon at the top-left corner.
