Lives for gear
John, thank you for the info. You're way ahead of me on this stuff.

- FWIW, some engineers (primarily in film post) used the Dolby A decoder as a single-ended NR! You had to be very careful to set levels so that dialog would be preserved but noise would still be downward expanded, but it did provide four bands of independent masking so could be more 'transparent' than a typical noise gate or expander of the time. This was before the Cedar hardware came out.
