Audio Interface - Low Latency Performance Data Base

Hey All,

I am sure all of us have seen posts over the years where end users have purchased a new audio interface and have experienced varying degrees of performance issues. A lot of the qualms have been due to the low latency performance, or to be exact, lack of , so I thought it would be a good idea to place the spotlight on that specific aspect of the current crop of audio interfaces.

By testing the interfaces head to head and reporting warts and all, I hope to place some of these developers on notice that jamming as many shiny baubles onto an interface , but neglecting the crucial aspect of the actual driver performance , isn't going to swing for all of us.

I have been working on this for about 15 months odd so the preliminary results were actually from earlier in 2010 , but are still valid and are a good starting point as I add further to the list over the coming month/years.

Here are some initial results for both Desktop and Notebook .

Desktop System Detail:
Intel i7 920 Quadcore/ 2.66 GHZ/
Intel X58 / 6 GB DDR3-PC12800.

Notebook System Detail:
Intel i7 620 Dualcore / 2.66 GHZ/
Intel HM55 / 4 GB DDR3-PC10600.

O.S Detail:
Windows 7 x64 Pro





All of the interfaces listed except for the baseline RME HDSPe units are FW and its quite obvious from the results that there are large variables in LLP- Low Latency Performance depending on the efficiency of the respective ASIO drivers / FW controllers being employed on the respective interfaces.

I have posted a summary of the initial testing at the DAWbench site Here

I have a second round of testing on the way which will include some of the newer AVID interfaces at both ends of the spectrum , Mbox Pro 3 and also one that I have had quite a few requests to put the thru its paces, the PTHD Native PCIe card.

Stay Tuned
