Both MP3 and CD use 16/44 (16 bits, 44kHz sample rate) formats. The
difference is that the CD will have the entire signal stored, while MP3
will remove some of the signal which is not as important as others.


You are partially right.. CD uses a specific sample rate and bit size,
And I believe you are correct as to what they are

MP3 can use a very wide range of sample rates, and different bit sizes
as well.... Crank the bit rate and sample size up enough and yes, I am
not going to be able to tell the difference. (A golden ear I'm not).

But the bandwith needed goes way up.

Some "Cred"info..My daughter, in whom I am well pleased, IS, among other
things, a Classical Musician and music teacher...In the past I have been
her "Recording Engineer" I also do recording in other venues as well...
Usualy ATRAC, but sometimes CD quality.

I have played a lot with Bit Rates, sample sizes and sample rates.using
Total Recorder PRO and the LAME codec.

Fun Fact: Remember Spaceship One, the one that won the X-Prize? Well,
Dr Space (David Livingston) complained during the first flight about
having to change cassettes in his audio recorder... I tossed Total
Recorder on the job and within minutes of the program end he had an MP3
in his mail box.

Next flight he mentioned his new log recorder (Total Recorder PRO) and
credited me with the suggestion.

I have hundreds (IF not thousands) of hours of live recordings lying
about here.
