I do think they pioneered this, going back to SONAR training equipment in WWII.
Speaking of half-speed cutting, I have never understood how this is pulled off in a modern context,
especially with Dolby-encoded master tapes. I guess it's possible to make the NAB or CCIR tape EQ
de-emphasis work at half-speed, and the RIAA emphasis at the lathe, but doesn't Dolby get screwed up
when frequency bands are lowered?
Today, I think one can listen to recent LP cuts by Bernie Grundman or Ryan Smith or Sean Magee and
hear that there's no need for half-speed if the cutting engineer and his cutting chain are
top-notch. I've heard arguments about fitting more bass energy on a disk at half-speed, but again I
can't understand how that's true since the disk will be played back at full-speed and hence won't
track on normal-priced systems if the grooves are too wide and deep.
