Geeks' Nook: File Formats

It's a chronic headache in the modern age: There are just too many file formats for digital audio and video. Only Apple players play the songs you buy from iTunes. Conversely, you can't play the copy-protected songs from any other music store on an iPod or iPhone.

So what, exactly, can the iPhone play? Anything iTunes can play.

Which means:

  • Video formats like H.264 and MPEG-4 (files whose names end with .m4v, .mp4, and .mov).

  • Audio formats like MP3, AAC, protected AAC (that is, iTunes Store songs), MP3, Audible (formats 1, 2, and 3), Apple Lossless, AIFF, and WAV.

Tip

A free software program called Handbrake (http://handbrake.m0k.org/), available for Macintosh or Windows, can convert DVD movies into the .mp4 files that can play on your iPhone. And a $30 Apple program called QuickTime Player Pro, also for Mac and Windows, can convert dozens of other formats into iTunes/iPhone-compatible ones.
