not really sure where to put this but here goes

I have 16 tracks to record at once for a live concert tomorrow night & the question is how much memory would 16 tracks eat in 1 hour of time??, the gig could extend & I want to be sure I get the whole thing

it's being recorded 24 bit at 44.1

thanks in advance
 
Wow..that could be quite a bit of HD space. I'm guessing at least 500 MB per track, for 1 hour. You are loking at 8 Gb. Obviously just a rough guess, but a 5 minute piece, just a kick drum can be 40MB or more...so it would be about 500MB per hour. X16, and you have 8Gb. Video is bigger, and 1 hr of AVI is about 13GB...If any of this helps.
 
Don't you think your missing a few variables here?

My thoughts exactly. Dogman already gave you a guess so I'm guessing your good. I was wondering like what hardware and software you're using, if you are using plugins, what format you're using, whether or not you are mixing on the fly etc., just stuff to narrow it down.

it's a pro tools control 24 mix+ set up with 882 & 1622 interfaces, I'm using very little plugins at this stage & no mixing on the fly as I have to be in the bands as well you see

the whole stage is going to an LX7 & in turn direct channel outs are being used to feed pro tools

14 tracks to the band, 6 for kit, 3 guitar rigs, bass, harmonica & two vocals along with 2xSE2200a's for room/audience
 
I would avoid using plugins since you're running so many tracks at once, and for a long period of time. I would add the plugins after recording if possible.

I would also test the computer by recording 16 tracks for about an hour or two and see what happens.

What are the specs of the computer?

Yep. I'd say, record as dry as possible...don't let the system bog down, if you can help it. Mix it later.

I've never recorded anyone but myself, so my figures were just based on what i've recorded, for storage space. I record 32bit, 44.1, myself. that is just teh default in my software, and I've never changed it. :D

I've recorded many many live concerts but only on 8-12 tracks & generally no plug ins, although I couldn't help tweaking as I was sound checking things
 
A single 44.1k/24bit mono channel requires just over 1 mbit/sec bandwidth. 16 such tracks come to just under 17 mb/sec. Allow for logistical overhead and figure 17mb/sec even.

Conver that to bytes, allowing for sector slack and a bit of safety margin and that yields a figure of 2.25 megabytes of disc space per second for 16 tracks of 44.1k/24bit mono; or a conservative rate of 135MB per hour for 16 tracks. the actual figure may wind up being a few percent less than that, but it's good to figure on the conservative side in these things.

If a PT Mix 24 system can't record 16 tracks for 2 hours straight without a glitch, just kill yourself! ;)

You will use about 7mb per track per minute. Do your own math!

CORRECTION: That's 135MB/minute, not per hour. That actually comes out to 8.1GB per hour. Sorry for the mistake.

it's cool I'll shoot you later :D

I got my drive cleared in preperation for set 2 & stupidly left my back up drive on which is where the audio was allocated to (STUPIDLY) & I only got just under 1/2 the 2nd set

how pissed off did I feel MAN!!!!

ne'er mind it was an awesome gig & lesson learned for next time :rolleyes:
