FLAC

Is it storing a literal analog signal in a digital way?

Or...

Is FLAC just an approximation of analog signal by having an extremely high sampling rate that simulates a sine wave instead of digital flat waves?

you can't store analog signal in a digital way dummy.

Of course you can, just store the formula instead of the sets of values, then it can be evaluated to get the analog value with some approximation error margin. Just finding it would be a fuckton of computing.

And yea flac is #2 since before signal gets to en/decoder it already got sampled.

>Is FLAC just an approximation of analog signal
FLAC isn't an approximation of any signal, it's a compression algorithm for a PCM bitstream.

Is it possible to do #1 before #2?

Doing #1 is practically impossible for audio.

FLAC is digital flat waves. You need something like AAC's quantization to smooth the flatness and give you proper sounding audio.
