Anyway it's probably more important to talk about the standardised DV25 and DV50
protocol all these commercial/prosumer products use for communication that
tape/card formats. There are some Sony and Panasonic camera that do this fine
over USB so it's not impossible or a problem with USB itself. I see yours (and
apparently many others) claim to have some kind of USB Streaming but for some
reason it's not usually full quality, as you would get from Firewire. Wonder
why...
Intel says that nobody really needs that low of a latency anyway in
response some sound cards problems with one of their implementations of
USB3. (the problem was USB2 cards with USB3 ports which are supposed to be
compatable)
In recording latency is not the issue it is with live work. For recording
latency needs to known and constant and reasonably low for monitoring. I
have heard/read people who say what does it matter if you move your head a
foot or two closer or father from the speaker? But in live work if the
same audio comes from different places it is called a filter.
Looking at some of the computers around and their latency spec, there is
no reason they should not be able to be used as a live mix engine for FOH
except the audio IF is too slow. Often this is because the IF includes an
internal router/mixer/effects section which I find useless anyway.
Looked at from a different POV, the cost of a digital mixer makes it an
atractive audio interface. For ~$2k you can have:
- 22 digital i/o (USB as happens)
- 16 mic/line preamps
- a 16 motor fader DAW control (can be MCP)
- 16 digital channel strips with complete eq+
- low enough internal latency for live work
- can be used as an on site live digital recorder (18 tracks)
- 32 track/channel available (for more money)
( http://www.allen-heath.com/ahproducts/qu-16/ )
That looks very attractive for a small working studio. For specialty mics
I would still use a dedicated pre if I could. The presence of eq and other
effects in this box should not preclude the use of other plugins in the
DAW as these are live related (make an sm58 sound good) and there may be
better plugins available in some cases.
I am sure there are other digital live mixers around with similar
features.
