MP3? AAC? AIFF? What's WAV?

How many tracks can I get on my iPod? What's the best balance of sound and quality?

Over the last three years I've drawn this diagram on odd scraps of paper so I thought it was about time I did it properly. The picture is expanded and I've added some notes explaining the key terms relating to digital music.

You'll find this helpful whether you own an iPod Nano, MP3 player, iPod video, Sonos or iMerge music player.

"First class CD ripping service. I'm enjoying music I'd never have found without you."

"Data grooming is fantastic. All the errors that were frustrating me before are now gone."

"iPod loading without the pain".

"Much better than buying my music again from iTunes Music Store."

"Got an iPod for Christmas. Loaded six albums but got bored, so three months later I thought I'd get you to rip the other 250. I'd never have done it without you."

"Fantastic sound and service. 300 CDs in one week. My wife appreciates the space we've saved."

"Thanks for working over the weekend. The mini iPod was a great leading present for -- and to find it had his favourite CDs ready loaded really made his face light up."

"Really glad you fixed all the composer names. As a classical nut this was vital."

"Getting all my music onto my iPod was great. Thought about for ages, just had to accept I'd never do it myself. You did it without fuss or drama. Thanks also for sorting out how I can listen to music all over the house."
