Latency in 1.1 vs usb 2 shouldn't be significantly different as I
understand it. usb 2 just allows higher bandwidth - so more channels
or 24bit vs 16bit. Just depends on whether the interface is properly
supported in linux.
Thanks Len some great information here.
Did you try 48k / 3 periods/buffer?
Also, is 10ms really so bad? I guess it depends what you are using it
for, but 10ms from pressing a keyboard to getting a note out is not so
bad at all - within the realms of analogue organ response times, I
think.. If you need to feed audio in and have near-zero latency, that
is a different matter..
For my live setup (virtual synth-rack) I am planning to rely on the
internal sound - at least in initial (rehearsal) tests.. Not too
worried as long as latency is <25ms and xrun-free.
Jack won't start lower?
Yes, Jack just won't start on lower buffer sizes with internal sound. Not
really a problem. just for testing. For live work,
Guitar effects, soft synths, etc. USB 1.1 at 16bit/48k may
work just fine
My experience with USB audio is limited, but USB 1 on mac, for live
processing, I have found to have unusable latency.
I will probably update this computer at some point and
convert all my
personal recordings to a Linux based system. My main reason for the thinkpad
was for gigs and live processing, so I am thinking a USB 2 audio interface
is what I'll go for.
Yes - I just got a scarlett 2i4 and heartily recommend it - although
haven't stress-tested it much yet. Quality seems very good!
Be careful though - not all usb2 devices are supported in linux..
Re: firewire - there was some discussion here a year or so back that
it might be being slowly discontinued - fewer laptops having as
standard etc, and most consumer interfaces moving to usb2.
