Re: [ARSCLIST] What type of file are music CD's saved as

Each point on the waveform is in a single, 16-bit sample. The 32 bits (one sample for each of the two channels) in appropriate order are the digital representation of the amplitude. Pulse-code modulation means that the sample is represented as such a value - or such a pair for two channels.

The difference between the stream and the WAV is only the ordering of the
32 bits making up the pair of samples.
