How to trim audio as a ringtone

iSkysoft Ringtone Maker for Mac will automatically preset a 40-second audio segment as a ringtone. The highlighted segment is what you get. If the audio is less than 40 seconds, the whole audio will be highlighted.  

Simply drag the highlighted segment to change the part you want to save as a ringtone.

To make a ringtone longer than 40 seconds (up to 60 seconds), drag the left or right slider to adjust the duration, or directly enter time points in the Start Time and the End Time boxes to set the ringtone length. 

Tips: You're able to select a new segment by holding down your mouse and dragging on the audio thumbnail. The Trim time indicates the duration of the selected segment.
