(Please excuse if this is a stupid question...)
I am learning Ardour doing some practice on my system (Debian
stable, RT kernel, RT tuning, MAudio Audiophile 2496 PCI, 3GHz 4core
CPU, 8GB RAM, JACK buffer 512). Working with a 3min stereo audio
(24bit, 88.1kHz) I have noticed DSP goes to 100% when exporting
(WAV)...
Is it normal (simply Ardour is using all the available resources
during the export) or something is going wrong (and I will have
glithces/pops in the output file)?
It's perfectly normal. Export puts Jack in 'freewheeling' mode
which means that it doesn't sync to the soundcard but starts
a new cycle as soon as the previous one has ended (the sound
card output gets 'silence' for output meanwhile, and input is
discarded). So things will run 'as fast as possible' which
means CPU load will go up to 100%.
Great.
Thank you for the clarification.
Ciao!
