Find the simplest ringtone, SMS ringtone and setting method of iPhone4 mobile phone.

You can only set ringtones, not SMS ringtones. The operation method is as follows:

Step 1: Open itunes, enter the music list and find the song you want to play, such as Direct Answer. Double-click Play, and you can see that the playing time is displayed at the top of itunes, and the recording time is the climax of the ringtone, such as 1: 05- 1: 35. The ringtone file size of iphone cannot exceed 40 seconds.

Step 2: Right-click the name of the song you want to ring, enter "Show Introduction", enter "Options" in the top label menu bar, enter the start time and stop time respectively, and then confirm.

Step 3: Return to the itunes music list interface, right-click the song again, and select "Convert selected content to AAC" in the menu. After that, you will see an audio file with the same name in the song list, but the playing time is much shorter than the original file. This is the parent file of the ringtone file we want: right-click the file, select "Display in windows Explorer" in the menu, and directly change the file suffix from "m4a" to "m4r" in the pop-up window.

Remarks: Many comrades sent short messages saying that the file suffix cannot be changed. If you find that the suffix does not appear after the file name, please take the following measures: 1. Open a file at will, and the following window will appear. For example, click Tools-Folder Options on the menu bar: 2. Check before "Hide extensions of known files" in View. Then double-click this file, and you can see that there is another list of ringtone files in itunes. Hehe, the ringtone was made in less than 2 minutes. Edit and update on April 23rd: According to the above instructions, after double-clicking the ringtone file with the suffix changed, there are no ringtones in the itunes ringtone list. The reason is that itunes is not set as the default player for playing .m4r format files on your computer, so ringtone files will not be opened through itunes and will not be added to the itunes ringtone database. Solution: Put the ring tone file with the suffix changed into a folder, and then add the ring tone file to the itunes repository through the File-Add Folder to Repository function in the itunes menu, just like importing music files, or right-click the original double-click operation and select itunes to open the file. The last step: synchronize iphone with itunes, select all the ringtones or select the ringtones to be synchronized separately, and then click "Sync" in the lower right corner to get it.
