[BC] CD vs LP

[RichardBJohnson at comcast.net]

Soundstream was founded by the inventor of digital
audio recording, Professor Thomas Stockham, of MIT.

He also invented, or was first to use RLE compression,
which I implemented as a technician.

His recordings used “true” 16-bit converters which had a
separate sign-bit so that the AC signal was + and – 65536
codes. Unfortunately, it had a “wide zero,” i.e., zero could
be both plus and minus. This produced a one-code dead-
band. Also, there was no dither for improving the low-level
resolution.  Nevertheless, it was the start of something grand.
