What you want is a WAV (or AIFF) in the format specified in the redbook: two channels, sixteen bits per sample per channel, 44100 samples per second, uncompressed PCM audio.

Okeh...this reminds me I had another question...!

Is not "PCM" a digital result converted from the actual digital audio
as sampled into a file based on when strings of "ones" (even if a single
bit) change to strings of "zeroes" (same caveat)...?!

So that a CD player has to convert that content into the actual audio
in digital form, which is then converted to an analog waveform used to drive the output transducer (phones, speaker(s), wotever...)?

PCM = Pulse Code Modulation. Basically, at each sample point, the amplitude of each channel is digitized and that value is stored. You ae writing of some form of incremental encoding.


Isn't this easier?
