Re: Vinyl introduces a lot of failings
actually studios used to use sony video decks as a cheap dig' second backup to the tape version master, but the sony's recorded at 48k, HHB in london started modding the sonys to 44.1 for studios. studio dat's were initially 48k, like my denon i had imported from japan, again it took time until 44.1 dats appeared. This was long before people commonly had consumer cd players and when vinyl was still king.
From John Watkinson, The Art of Digital Audio, 2nd edition, pg. 104:
"Video recorders... were adapted to store audio samples by creating a
pseudo-video waveform which would convey binary as black and white
levels. The sampling rate of such a system is constrained to relate simply
to the field rate and field structure of the television standard used, so that
an integer number of samples can be stored on each usable TV line in
Such a recording can be made on a monochrome recorder, and these
recording are made in two standards, 525 lines at 60 Hz and 625 lines at
50 Hz. Thus it is possible to find a frequency which is a common multiple
of the two and is also suitable for use as a sampling rate.
The allowable sampling rates in a pseudo-video system can be deduced
by multiplying the field rate by the number of active lines in a field
(blanking lines cannot be used) and again by the number of samples in a
line. By careful choice of parameters it is possible to use either 525/60 or
625/50 video with a sampling rate of 44.1KHz.
In 60 Hz video, there are 35 blanked lines, leaving 490 lines per frame or
245 lines per field, so the sampling rate is given by :
60 X 245 X 3 = 44.1 KHz
In 50 Hz video, there are 37 lines of blanking, leaving 588 active lines per
frame, or 294 per field, so the same sampling rate is given by
50 X 294 X3 = 44.1 Khz.
The sampling rate of 44.1 KHz came to be that of the Compact Disc. Even
though CD has no video circuitry, the equipment used to make CD
masters is video based and determines the sampling rate.
