- It is instructive to read the minutes of the standards commitees in
- the AES from around 82. 44.056 was used only because 44.1 wouldn't
- work with ntsc VCR's: for PAL it was always 44.1. The AES wanted 48kHz
- because of compatibility with the 24frames p s of motion film. They
- pleaded (their word) with Sony not to adopt 44.1. Sony said it was
- "a business decision, not a technical one" and stuck to 44.1
- There was also a strong push to limit frq response to 16kHz.
- At the time there were various digital practices: Telarc, for eg,
- used 50kHz. Several Hollywood studios had 48kHz digital edit suites,
- apparently little used (too hard to edit on).
