However a failed patent by Murray Crosby created the copying of that contained information (somehow) which created research into companding
Companding being
https://en.wikipedia.org/wiki/Companding products then that were made by Dolby and DBX and many others enabled raw devices to
provide much greater dynamic range. DBX and Dolby have been a feature of almost every recording since 1965
Now why audiophiles have yet to catch up with the benefits companding provides remains a deep mystery, hopefully now to be investigated.
A cursory look provides very simple somewhat crude methods have been offered to consumers ie Dolby B. or Type 2 DBX simply because there is no discussion
or interest.
Surely this is what a forum like this is about, to raise awareness of an attribute for audio reproduction.
Anyone with a Dolby A or other more modern equivalents like Dolby SQ, hands up.
Back to Murray Crosbys invention ..RIAA is a reverse emphasis deemphasis curve, anyone know why ?
DBX too need to be contacted to start building a Type 4 digital domain product, and not hide behind
the fence offering Type 4 just with their poor analog stages. DBX have every ability to release
a world class product, holding a major slice of patents. need I say any more Harmon owners of DBX
now taken over by Samsung. Oh Dear !
Maybe as a suggestion Nebo should demonstrate companding equipment, by simply recording a CD
on to a audio hard disk recorder with and without companding. Could be interesting
