P800 ringtones

The P800, unlike it's newer sibling the P900, cannot play an MP3 as a ringtone. It is restricted to normal ringtones (which are MIDI based, i.e. they only reproduce the melody of a song, not the actual sound or any lyrics) and WAV files.
Unfortunately, a WAV file is by definition uncompressed, which makes them enormous when compared to the phone's memory. An average MP3 that is 4MB in size, when exported to WAV with QuickTime Pro at the default settings (48KHz, 16bit, stereo), will weigh in at around 50MB in size! How can we reduce the size of our WAV file? Luckily for us, since the file is only for a phone's ringtone, and given the limited speaker in the phone, we can drastically reduce the fidelity of the WAV file to the minimum possible and still have a recognisable song. Using the minimum settings (8KHz, 8bit, mono) when we export to WAV, our output file comes out to about 2MB in size. This is of course for the entire song - for a ringtone we only need about 15 seconds of the song which at the same settings will somewhere in the 100KB range. Qtplayer Bookends

To cut out the section of the song we want, use the 'bookend' markers underneath QuickTime Player's position slider to select the portion of the song you want to keep, copy it, and paste it into a new empty QuickTime Player document. We can then export to WAV from this new document. To export to a WAV, simply choose Export (this requires QuickTime Pro), select WAV, click Options and choose 8KHz, 8bit, mono. If you have a lot of MP3s to convert you may wish to have a look at SoundConverter, a great drag-and-drop audio conversion application. It is free for input files under 500KB in size, otherwise it costs US$10. What I do is cut my MP3s in QuickTime Pro, save them all, and then batch convert the lot with SoundConverter (once your MP3s are cut down to size they should be quite a bit smaller than 500KB).
