My Ableton shows that I have input and output latency = 11.6ms, so in total it's 23.2 ms. I think it's too much. I'm using Focusrite Saffire 6 (usb 1.1) and I wonder if I should but sth with 2.0 usb... My question is What has a greater impact on latency: CPU/GPU or DAC (usb version)?

1 Answer 1


All the ultra-low latency DACs are either Firewire or PCI, not USB.

Completely by coincidence, I was looking at Gearslutz yesterday & came across this
Audio Interface - Low Latency Performance Data Base :

There's far too much data to even try to summarise, & also 29 pages of discussion over the main post. I might try to squeeze some kind of précis into here once I've waded through it myself.

  • ok, thanks! I'm counting on you Tetsujin :)
