Isn't a small part of the "problem" that, in order to bolster the robustness of the data, one bit of the 16-bit word is not a datum that represents digitized music, it is a "Checksum" bit. So, there are only 15 bits available for recording, at best.
The purpose of the "Checksum" bit is to indicate whether summing the other 15 bits results in an Odd or an Even sum (or total). If there is a conflict between the sum and the Checksum, Error Correction kicks in.
Pretty darn clever, I thought back in 1983, or whenever it was I was recruited to write for Digital Audio magazine. I was also impressed by the Reed-Solomon Interleave Code.
