[HOWTO] iPhone Hacking – Custom Ringtone and SMS Notification
Posted by Mr. IT Guy | Filed under Howto, IT in General, Mac OSX, Microsoft
Following up on the earlier iPhone hacks is customizing the most common audio: ringtone and SMS notification. Apple has locked down custom ringtones and profit from them. The biggest problem is, their selection is scarce and sucks. Here’s a simple guide on how to upload the Ringtones:
- Choose an MP3 file and trim it to 30 seconds or less – I use Audacity (download link) to do it
- Import that MP3 into iTunes
- Goto iTunes -> Preferences (for Mac) or Edit -> Preferences (for PC)
- Navigate to Advanced -> Importing tab and set the “Import Using:” to AAC
- Find the trimmed MP3 file inside iTunes, right click and choose “Convert Selection to AAC”
- Right click the AAC version of the file and choose “Get Info”
- Note the path to the file as indicated by the “Where” section under the “Summary” tab
- Navigate to the location of the file and copy it to desktop
- Change the extension of the copied file to “.m4r”
- Open the files in iTunes and it should be automatically inserted under Ringtones category, which then can be transferred to iPhone
NOTE: I have tried to use “SoundConverter” and set the file type to be m4a. This actually doesn’t work. When I did it that way, the file will be uploaded but won’t be able to be played. It might have something to do with the file size generated by “SoundConverter” being too large. Read the rest of this entry »
