Step 1) Open Mobile Music Converter.
Step 2) Click on '+' sign on the left of the screen. This will let you find the files on your computer. You click on the file(s) you want to convert and you will now see it in the large box next to the '+' symbol from earlier. You can select multiple files in one go for conversion.
Step 3) By the output file/folder box click on '...' and choose where you want the converted file to be saved. I always use the desktop.
Step 4) Click on the 'Conversion to' drop-down menu and select your chosen file type, in this case Ogg Vorbis audio. Then click on the Quality drop-down menu and select 'High'.
Step 5) Click on Convert Now! Your converted .Ogg file will now appear on your desktop, ready for you to move to the SH3 gramaphone file.
Good luck and may your gramaphone ROCK!
