Re: [ARSCLIST] Format conundrum

Hi Richard,

It would seem as though a way to achieve this would be to use the paper tape that was is used in the early computer days, not individual sheets of paper. The paper could then be created with archival paper specifications.

Hi, Steven,

Are you suggesting that we then OCR it back into the computer?

Let's see. 88,200 samples per second, 24 bits.

Lets, for the sake of argument print it as binary since we can't seem to
all agree on the ASCII/Windows/ANSI/etc representations of some of the codes.

So, we have a page of 1s and 0s. We would have 2.2 million 1s and 0s per
second.
Even if we developed a true 8-bit glyph, we'd have 265,000 of them per
second. Let's figure dense printing: 120 characters per line and 80 lines
per page, or 9,600 glyphs per page. We'd need almost 28 pages per second
per channel. A stereo 40 minute recording would require over 132,000 pages.

Now, granted, that's at higher definition than an audio CD.

Doing the same numbers for a CD using the 8-bit glyph gives you 44,100
pages for the same 40 minute recording. (I didn't plan it to work out that
way <smile>.

Cheers,

Richard
