Right, here is what i do for Windows Vista Home Premium
What you need is
Audacity
Encoder
pick a song you want to have as a ringtone
select the part you want to use and cut it to size between
30 -39secs long using Audacity
and have it no longer than
39seconds
once you have picked which section and the correct length, export it as
MP3
(at this point Audacity will ask you to point to an
encoder, point it to the encoder you should have downloaded earlier
then drag the MP3 file into you
MUSIC list on iTunes
then right click on the MP3 in iTunes
and click on "
Convert Selection to AAC"
once that has converted it, you will have the 2 files, 1 MP3 and 1 AAC
delete the MP3 file which leaves you with the AAC file
Right click on the AAC file and click COPY
go back to your music folder in
My Documents and perhaps setup a folder in the called Ringtones
and PASTE the AAC file into the RINGTONES folder.
At this point you need to have your file settings to show your file extensions, how you do this is once your in your Music Folder in Documents
Click on the top left Organize
Which gives you the drop down menu, Select Folder and Search Options
Then you get the Folder Options Menu, Click on the View Tab
then take the tick out of Hide extensions for known file types
then click Apply then OK
Right, then go back to you music file you copied and it should now have after the file name .m4a
Right click on the file and click rename
then you can change this to m4r
it will then ask you do you want to change the extension of the file
which you click YES
then once its changed you just Double click on the song and it will Automaticaly go into your ringtones section in iTunes
This sounds Long-winded but its really easy to do.
