I would choose between 44.1KHz and 48KHz on the multitrack recorder,

oversampling (provided a small use of DSP), am I wrong?
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)?
To change things to 48k you would have to do that outside of ardour. I
would suggest against doing that except as a final step after mixdown
as any time differences from track to track in the resample would be
magnified by such a long track. Even in shorter cases stereo imaging
could be affected. It would be best to leave 44100 if at all
possible. If the end product _has_ to be 48k then expect a (hopefully
small) loss in quality.
Ardour will switch it to 32bit float internally whatever the input is
to allow mixing headroom. 24 bit is chosen at export time. However,
again this would be decided by the final delivery route.
Thank for this information, i didn't know of this behaviour.
