It feels like we're having one conversation in two threads. See my last post in the other thread for the answer to this question. The key point is that the 1D voltage (and the 1D sample sequence) does not permit reconstruction of the original 3D wave as it was in the room. What it permits is the reconstruction of the 1D acoustic wave recorded by the microphone, which is a "slice" of the full in-room 3D acoustic wave of the performance. What's missing in the 1D slice is extra information added by the room itself: if we subtract the 1D slice from the 3D original, we'd mostly hear "room sound", such as reverbations and resonances.How is it that the numbers, representing simple voltage fluctuations is permitting a full analog reconstruction of the 3D wave so as to be able to access constituent parts of it post-recording??
The “sequence” of numbers is literally representing waves that should technically “not exist” after the mic picked it up, save for extra-dimensional rationale.
