Being the person in question, I have to point out that what I am trying to
convince him is that the process of converting from the analog domain to
the digital domain at CD-DA sampling rates is in fact a form of lossy
compression. What you get out is smaller than what you put in (compare
with analog recordings on optical media like Laserdisc), and some
information is lost in the process. If it walks like a duck....
Ummmmmm....you can't call the process of analog to digital conversion
compression, you aren't making the audio smaller, your simply sampling it
every so often. Analog doesn't take space, your limited by the speed and
amount of media, so you can't say that a CD is compressed vs a casette. A
casette can hold an hour of music or 8 hours, depending on what speed you
have it running. If you used optical analog techniques on a compact disc you
can vary speed and get more or less time.
Yes, you lose stuff then you digitize, BUT compression removes stuff from
the auctual digital waveform to make it smaller as where digization
preserves the wav best it can.
It's NOT compression.
