Just set the exact Start and End time in the timeline or fill in the specific Start/End time in the box.

After you have finished set the Start/End time, click OK and come back to main window. You can click the thumbnail to pre-listen the MP3 music clips.

Step 2: Choose M4R Ringtone as Output Format

Click "Profile" (move the cursor towards bottom side) and head to "General Audio" in the dropdown list from which to select "M4R – iPhone Ringtones (*.m4r)".

Audio Settings as below (click "Settings" next to "Profile") help you choose the optimal encoding property in terms of Encoder, Channels, Bitrate and Sample Rate.

Please note: The encoder for M4R ringtone should be AAC.

Step 3: Start Converting MP3 to M4R on Mac

Click "Browse" (below "Settings")and choose a location where the results will be saved and give it name.

Once you get everything ready, click "Convert" and get it started. What matters to the conversion speed includes source audio, its output settings and the Mac's performance.
