and a card reader to transfer the files via SD card to your phones
You will also need to rip the wave file I use the Sound Recorder provided with Windows.
Step.1 Convert the mp3 into a wave file using dBpowerAMP use these setting
16 Bit (CD)
8000Hz
2'Stereo' (CD)
press convert
( I always create a new folder to save the converted files into that way they don't get mixed up with the originals)
Step.2 Using the Sound Recorder provided with Windows rip the wave file to your favourite bit this must be under 11 seconds long ( it is important that the ripped wave file is 11 seconds or under other wise it will be to large for your ringtone and it will not be playable after it,s converted into SMAF file. at this stage I also increase the volume of the wave file you can do this through the effects menu ) rename and Save the ripped fill ( shorten the title to less than 26 letters this is very important )
Step.3 Open the Yamaha Wave to SMAF converter drag the renamed wave file into the converter window and press OK ( check that when the file is converters it,s less than 50KB ).
Step.4 On your SD card create a folder name it Sounds ( whilst its in the card reader ) drag the SMAF file into the Sounds folder and put your card back into your phone.
Step.5 On your phone go to My Stuff scroll down to Sounds, then to Memory Card there your phone will find the SMAF files play the file press the Options button scroll to Move to Handset.
Step.6 Go to Profiles on your phone press Options scroll to Personalise then Assign Ringtone then My Sounds and there will be the SMAF file you created press center button on your phone
