Audacity, Hydrogen, and Ardour work great with Jack controlling the Hardware

The trick is to get the applications to connect together to the audio
interface. If you set Audacity to connect directly to the sound card,
other applications cannot use the sound card resources.
Basically, you have to send all request for the sound card through
Jack. ALSA has the drivers and Jack controls the connections. Setting
Audacity fixed this problem.
In my Ubuntu Studio (US) hardware I use one Delta Revolution 7.1 sound
card. The internal or motherboard (mobo) sound interface is off in
the BIOS. My goal was to only use the Delta and so far I am proving
my theory because it performs excellent under long complicated
recording sessions.
With 2 Gb of Memory and plenty of Hard Disk Space, the programs ran
together with no problem. I just did a couple of loops and recorded
audion directly from my synth. This would have killed my Windows
machine. US handled it quite well. The only noticible latency was
when I decided to hit record in Audacity to see if Audacity and Ardour
could record at the same time. This was extreme and I thought that
something would crash. Well...nothing happened! They both were
recording! It slowed down for a second then the system caught up. I
was impressed. I would never try this with Windoze. I may try it
with a MAC but never Windows. However it was an extreme condition and
I woul not do this again.
I do advise as they suggest in the forums that you use two harddrives
on separate controllers. I do not recommend using RAID SATA or other
RAID internal or external devices. Audio needs to have full attention
of the drive and controller.
The other question in funtionality has to do with fragmentation and
drive maintenance. All of my studies indicate that the drive format
EXT3 does not need to be defraged. I have been working on several
complicated Podcasts with Loop recordings built in Audacity and the
system never glitched. I keep my archives on DVD medium therefore, I
keep the space on my drive for production. I do not do complicated
video on this machine. I am curious to know how things will be over
time. I will keep notes on that progress. Images are forthcoming on
the BLOG for the audio connections with Jack.
