Hello list,
For the first time in my life I need to work with huge
recordings, I would like to understand how much memory and
computing power is required to handle it on a linux box with Ardour.
The recording, retrieved from an Alesis hd24, will be about 1
hour and a half long, 24 channels, 44.1KHz, 16bit,
What are the minimal requirements to work with it?
If I choose sample rate and bit depth to be 48kHz/24bit, will it
require much more resources (other than disk space)?
you could record that on a 400MHz Pentium II (i.e. a box about 12
years old) - you don't need any big hardware to record data like
that.
now, when it comes to editing, the question is a bit different, but
the *size* of the session in terms of duration is largely
irrelevant. 24 tracks is manageable on just about any modern
machine. if you edit it so that there end being hundreds or
thousands of regions, that could cause issues, but by itself, the
data size isn't really significant.
what demands big resources are
* disk i/o, but 24 tracks should be manageable on any modern disk
* plugins, which use (potentially) lots of CPU while processing
audio
without knowing plugins you plan to use, it is hard to predict what
you would need in terms of CPU power.
with no plugins, it would be hard to buy a computer today that could
*not* handle editing that session.
All true. 24 channels, 44kHz and 16bit should not cause problems on
any mid-recent machine. I routinely handle sessions with 24 channels,
48kHz, 24bit. Mostly about 6 busses. CPU-usage can then be a bit high
if you have dynamics and an 8-band-parametric EQ on every channel +
cpu-intensive plugins (ir_lv2, ...) on the busses.
Just try it out and you'll see how your CPU can cope with the DSP
load.
Of course more RAM is better since you can cache disk-reads but as
Paul said: any recent machine should be able to get the work done.

Ok, that's what i hoped, since i don't expect to make heavy signal
processing. I think I would not have any problem with it.
Thank you all for the kind responses.
