Things You'll Need:
- MP3 version of the sound or song
- LAME Library
- Sound-editing software
- Cellphone that supports custom ringtones
-
Step 1
Direct your sound-editing software to where the LAME library is located on your computer.
-
Step 2
Make a duplicate of the MP3 song or sound you are using for the ringtone, and move that copy into a separate file to work on it. This will prevent you from losing your original MP3.
-
Step 3
Open your MP3 into your sound-editing program, and find the 15 to 25 seconds you would like to use as your ringtone. Crop that section out of the original MP3.
-
Step 4
Export your new ringtone as an MP3, and save it with an appropriate name.
-
Step 5
Connect your phone to your computer using a data cable or Bluetooth connection to transfer the ringtone to the phone. Alternatively, you can email the ringtone file to your phone if your phone supports that service.
-
Step 1
Download free sound-editing software from the Internet. Audacity (available for Mac OX, Windows and Linux) is one of the most popular and widely used versions (see Resources below).
-
Step 2
Download the LAME compression library for free (see Resources below). Store it on your hard drive where it won't be accidentally deleted.
