What sort of straight recording (no plug ins, stereo monitor mix)
track count @ 24 bit/48k
could I expect with a current G4 IBook and DP4 or PT 6? With a P4 1.8
Gig PC laptop?
(PT6 or Audition or Samp.) How does one determine this, other than
trying it? Is this not enough info to get a real answer?

thanks

5 Megs per track is a good starting point. Why do you want to use 48K? There's
so little difrence from 44.1.

It's no info at all.

You need the harddisk throughput rate, that is the limiting factor.

24/48 = 144kB/s.

Harddisk throughput is usually around 20MB/s, good for about 100 channels.

There may be other limiting factors, but CPU, memory, interface (e.g.
firewire or USB2) aren't the limiting factor.

As many as you can afford input devices for.

For video audio--which is all 48k. I was speaking of the ability of a CPU to handle
the recording of X number of tracks at once, not disk space.

I think a factor is whether the hardware you use to record with has
its own dsp for monitoring input signals. Other wise you would be
doing it via software and that would put a big lag on the system.

If we were to believe this former poster, you should be able to get a
100 tracks from a hard disc. I don't think so. The more fragmented a
hard disc is the harder it will have to work to write new data.

You will essentially need an external hard disc with a laptop. The
ones that laptops come with are often lower rotation speeds because
they need to conserve power since laptops have heat problems and need
to run off batteries as well.

I would assume with the right hardware and an external disc you could
record 24 simultaneously at 24/44.

Things you have to look out for is configuring your system to not run
stuff in the background that can cause a sudden unknown hit on the
system and to defrag the recording drive periodically. Get as much ram
as you can and firewire is generally considered better than USB for
the external drive.

Assume 96Kbytes for 48Khz 16 bit. 100 Tracks is 9.6 megabytes per second. Go
24 bits and it's 14.4 megabytes/second.

Dunno, but I'm doing around 30-40 tracks on a G4 Powerbook with Nuendo.
