Hey
I've just put in a REM Digi96/8 in my computer and attached it to a
Behringer ADA8000 interface. I can se all the ADAT ports so it seems all
okay so far. But I wonder how I can calculate the best setup for my card
so that it uses a minimum of processor time. I've managed to setup my
jack with these settings:
JACK compiled with System V SHM support.
loading driver ..
apparent rate = 44100
creating alsa driver ... hw:0,1|hw:0,1|256|4|44100|0|0|nomon|swmeter|-|
32bit
Is there a simple formular to use to calculate settings such as
Frames/Period SampleRate Periods/Buffer.
Thanks in advantage

If what you mean is how to get the lowest latency, I believe the
formula is:<br>
<br>
(frames per period X periods per buffer) / sample rate X 1000 = latency
in ms<br>
<br>
Note Ardour often shows a different latency than JACK - not sure yet
why - initially I thought perhaps it was showing one way rather than
round trip latency, however my JACK latency shows 2.67ms while Ardour
shows 0.7ms...I choose to believe Ardour ; - )<br>
<br>
Here's a simple calculator in OpenOffice attached...<br>
