CD audio is sampled 44,100 times per second per channel.

During the recording process it's sampled 44.100 per second?

Yes.

My friend claims audible data is lost during the sampling process.

I don't see how that's possible if the source is sampled 44,100 times
second?

All sound at frequencies 22.05 KHz are totally lost. Noise is added, which
obscures very faint sounds. However, it is highly questionable, to say the
least, whether these loses are audible.

What does 16bit or 24bit mean during the recording process or playback
process, e.g., Denon 3803 16bit and Denon 4802 24 bit, 96kHz A/D
conversion?

The number of bits can be a significant factor in determining how low the
inherent noise of the recording process is. All other things being equal, a
16 bit process puts the noise down no further than about 93 dB. For 24 bits
noise is down no further than 144 dB. Note that I say "no further". When
manufacturers say that a converter has "16 bits" or "20 bits" or "24 bits"
they are saying how many bits are processed in the digital domain.
Converters are hybrid devices, that exist in both the analog and digital
domain. Most of their imperfections are usually in the analog side. A
converter that is "24 bits" may have more noise on its analog side than
another converter that is "16 bits". In fact, very few converters perform
beyond the 20 bit level. The converters in most consumer equipment performs
at the 14 to 16 bit level, no matter how many bits are processed on their
digital sides. The ear has a hard time hearing improvements beyond the 13 or
14 bit level, in typical use for listening to pre-recorded music in the
places and circumstances where most people listen to music.


I use Denon as an example only because
I own a Denon receiver. Years ago, I read an article in Stereophile
that described all of this. However, my memory isn't what it used
to be.

He's probably just posturing. . . . . .

No he isn't, just a rigid guy who hasn't listened to good audio
systems in years.'

IME many people who tout the superiority of vinyl are actually attracted by
a kind of sentimentality factor.
