I'm querying a CD as follows:
cdparanoia -sQ -d /dev/sr1
[...]
11. 2603 [00:34.53] 256097 [56:54.47] no no 2
12. 15655 [03:28.55] 258700 [57:29.25] no no 2
13. 30220 [06:42.70] 274355 [60:58.05] no no 2
TOTAL 304575 [67:41.00] (audio only)
That 'TOTAL' figure of 304,575 is measured in, what? exactly? Sectors? Bytes? Something else? If I divide 304,575 by the 4061 seconds of the recording, I get 75 -and I believe there are 75 sectors per second on Red Book CDs, so I *think* it's sectors, but I would appreciate confirmation from someone who knows what they're talking about!
I then rip the CD with the command:
cdparanoia -B -e -d /dev/sr1 --never-skip=40 -O 6 1>/tmp/rip.log 2>&1
...and when I tail the resulting log file, I see this at its end:
##: -2 [wrote] @ 358177847
##: -2 [wrote] @ 358179023
##: -2 [wrote] @ 358180199
##: -2 [wrote] @ 358180200
##: -1 [finished] @ 358180199
Done.
What are these numbers? They are several orders of magnitude greater than the number of sectors, so is it bytes read or something? When I divide the 358,180,199 by the earlier 304,575, I get a result of 1,175.999... and when I repeat this for other CDs, the same ~1176 multiplier comes up.
For example, using a second CD:
4. 71291 [15:50.41] 187759 [41:43.34] no no 2
TOTAL 259050 [57:34.00] (audio only)
...and then...
##: -2 [wrote] @ 304642800
##: -1 [finished] @ 304642799
Done.
And 304642799÷259050=1176, near enough.
So the ~1176 multiplier appears to be a constant, but I haven't been able to find any reference to what it is or what it represents. Can anyone shed light, please?!
By way of explanation, I'm trying to take the last number contained in the log file as it's produced and dividing it by some denominator that represents the maximum amount of work needed to rip the entire CD. So, in that last example, I want to take 259,050 and turn it into the 304,642,799 so I have a denominator. I am currently doing that by multiplying the 259,050 by 1176 and then subtracting 1175... and it seems to work OK and I could just keep on doing it 'blind', I guess. But I'd like to understand what each of the numbers I'm using actually represents and why the 1176 number keeps appearing.
Appreciate any insight, anyway.
