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.
