For my phone, which is a Samsung A737, you can record sounds for 15-20 seconds and make this your alarm tone. But it doesn’t record very well for music. So, this is how I was able to import an alarm tone (.mmf) to my cell phone:

1. In my case, I had a music file which I downloaded for $.99 from iTunes (music file format was .m4p.) Even if you don’t have an iPod, I think this is a pretty good way to buy music, if you have conversion software (see #2). I had to find where the music file was stored on my computer by the iTunes library - for most people I would guess this is under “My Music/iTunes/iTunes music.”
2. Since I like my MP3 player - and see no need to upgrade to a $300 iPod – and bought most of my music through legal Napster originally - I found I needed to convert iPod music (.AAC or .m4p etc) anyway, to be able to upload it to my MP3 player. So I downloaded a free converter. I would recommend the imtoo.com/wma-mp3-converter which will let you convert songs up to 5 minutes on the free trial version, and also lets you split the music into smaller clips. [I actually ended up buying the software though and think it’s pretty good].
3. Once you install the free converter and open it, add your music file and choose to convert to a .wav file first. Note that alarm files (.mmf) apparently need to be small to work, so configure the split (you will see this as an option on the converter) to 00:00:16 seconds or so. I would save to the same location as the original music file so you can find the .wav files – you will see there will be a lot of 16 second clips.
4. Listen to the music clips (16 second .wav files) to choose which clip you like best for the alarm.
5. Now you need to convert the best music clip from .wav to .mmf. I would recommend another free software at smaf-yamaha.com/tools/downloads. Again, save the .mmf file to the same folder.
6. I tried some shareware out there which lets you send files to your phone, but .mmf files were not supported and could not be sent. I also tried to send myself the .mmf file by yahoo e-mail to my cell phone, but could not download the attachment to my phone. Maybe there are ways to do this. But I ended up buying a data cable for $9.99 plus shipping at: cellphoneshop.net/a747cable USB Data Cable For Samsung a737. To download pictures off your phone it is probably good to get this anyway.
7. Now, you can easily move the .mmf file to your “Audio” folder on your cell phone. It will be there to choose next time you set your cell phone alarm properties.

Hopefully I have saved someone from the agony of waking up to “Here It Comes.mmf” or what have you, for the last #$%^&*( time. That is why I spent so much time on it!!!!P.S. I have attached my .mmf file!

Is there a way to create my own .mmf files to download to my phone to use as text and alarm tones?
