Like some other digital sound sources these days, the sound quality of iTunes is very poor. In fact, it's about the worst. Apple uses an utterly crushing data compression scheme so that kids and the unknowing masses can store zillions of songs on their iPods -- at the expense of audio quality.
All digital music media has been sampled, and the number of times the music has been sampled is a key determinant of its ultimate quality. With commercial CDs, as an example, the original music (from the master tape) has been sampled at a bit rate of 1,378 kilobits per second. The bit rate for iTunes is -- hold onto your headphones -- 128 kbps. :shocked: That's less than one tenth the sample rate of a commercial CD. So when some people talk about iTunes songs not sounding very good, they're telling the truth. They don't sound good because huge parts of the music's original fidelity have literally been
removed by the compression process. Apple could fix this by using a lossless data compression process that would compress the data during download but restore it during playback, but they choose not to (presumably 'cuz it would add to the cost?).
Anywho, I don't know enough about iPods themselves to comment on the fidelity if a source other than iTunes is used. Hopefully there are some other sites/sources you can get songs from that don't use such overwhelming compression schemes. Now that I think about it,
I'd kinda like to know if there any other better sources out there and how their downloads sound on iPods. Anyone care to chime in on this?
