Prevent latency, USB controller/channel
Like many others, I want to achieve the least amount of latency etc., using a USB sound interface.
My computer has various USB ports/controllers. 2 x USB2 - 2 x USB3 - 2 x USB3 front.
I believe someone said it is best to keep the sound interface on it's own separate USB controller/channel on the computer, to prevent latency/interferences.
In other words, not sharing the sound interface USB lane with other peripherals.
Is this still advisable today?
And, could I buy an extra USB i/o card to get another separate USB lane?
Interfacing via USB is not the best way of minimising latency. Direct PCI/PCIe will always give lower latency, and even FireWire on a PCIe card will give lower latency than USB, even if the transfer rates are lower. Having said that, a motherboard that has USB3 capability will probably give you sub-millisecond latencies, but try to avoid having other peripherals on USB ports sharing the same controller channel.
Also, audio latency as a lot more to do with drivers and buffer adjustments and software that runs in the background (antivirus etc..)
pcrecord: Yeah I'm trying to optimize every bit I can, incl. those things.
Boswell: PCI card.. hm I actually thought that was history in favor of usb/firewire. Must check up on it. I remember RME cards
Ok, looking at the total price for a PCI solution far exceeds my budget.
So I'll stick with USB for now, and just optimize it best I can
