iPod and iTunes: The Missing Manual, Third Edition

Problems with Song Quality

The sound quality of your digital audio files is affected by a number of things. If you find that your MP3 files sound thin and tinny no matter what you play them on, check the bit rate you used to rip them from the original CDs (page 90). Bit rates below 128 kilobits per second generally don’t have CD-quality sound. If you’ve downloaded songs from Web sites, you’re usually at the mercy of whoever encoded the songs in the first place.

Some Songs Skip

If the same songs always skip, the song files themselves may be damaged. Maybe a hiccup or power fluctuation while you were ripping the tune from a CD dinged up the file, or maybe you had several memory-hogging programs open and running while you were recording songs. Try deleting the song files from iTunes and then reripping and reimporting fresh copies.

Shaking or banging the iPod while it’s playing can cause its hard drive to skip while playing a song. (Shaking and banging are two things you want to avoid with any hard drive.)

True, the iPod comes with a memory stash designed to prevent skipping for at least 20 minutes. But as noted on page 88, enormous song files—either hugely long pieces of music or files encoded in uncompressed formats like AIFF—could be maxing out the iPod’s RAM buffer. Here are your options:

• Rerip AIFF or WAV files into the smaller, compressed MP3 format. They may not sound as pure, but they’re less likely to skip.

• Break down larger files into smaller ones. If you’ve used the Join Tracks ...
