How good is the quality of itunes downloads compared to CDs?

Question

When I listen to them I find it hard to notice any difference. So I would like a more scientific answer. Thanks.

Answer 1

Actually, CD's audio is sampled at 44.1 kHz, so for stereo, we get:

44,100 samples/sec x 16 bits/sample x 2 channels =

1,411,200 bits/second for a stereo bitstream

If you want to try to detect problems, try listening to the high end frequencies on a good speaker system (not earbuds) with a CD and an MP3. You can also often hear problems with distortion at the low end (i.e. drum beats) with a good woofer.

Answer 2

CDs will, on the instant, continually have extra effective sound. they are an uncompressed organic archives format. a typical music (one music) on a CD runs around 50-60 MB, at a similar time as a 128KBs MP3 archives are around 3-4MB. at a similar time as incredibly some the sound is in simple terms too low or too severe for our ears to discover, there remains some mellowness in a 128Kbs MP3 report. I even have individually used countless report formats, and that i say that 256KBs MP3s/WMAs sound enormously lots appropriate to an CD. you will purely be waiting to observe this with severe high quality headphones, on the grounds that low-priced headphones wont additionally be waiting to supply the highs and lows which may be on a 256Kbs and over MP3 report. in case you have the CD i desire to propose ripping it at 320KBs MP3 format, for downloads you're starting to be the possibility of having a 128KBs report, yet i think that maximum downloads are going to 256 and better.

Answer 3

Well if you transfer songs from a cd to computer it becomes digital and songs from itunes is also digital and digital does not loose quality.

And cd quality is about 128kbps

That is what i think but i could be talking under correction

Answer 4

The songs on CDs are better

They are lossless and are about 512 kbps

Itunes songs i believe are 256 kbps which is basically standard

Answer 5

Is there a difference? I think electronic distribution would be BETTER because there are no scratches or skips.
