USB 2.0 Audio Interfaces

[Hannes]

I´m just wondering as I´m looking at the deejay trim as well,
mostly because of the 3 USB ports which is really great for additional Controllers

2,2ms latency seems quite high to me, although it really isn´t, i get 1,3ms with the U46 and 0,7 with the Audio8 (which i just sold btw cause NI´s Support suc**)

It's all down to how powerful your laptop/PC is, and not just how good your sound card/interface is.

2.2 m/s is very good compared to other cards of a similar price.

I see, so it´s actually your machine´s latency that you set within the preferences

thx for explaning

44100Hz at 96/2ms

I could not get my U46 to such small values and I agree with Jim, it depends on your computer.

P.S.: Why does the NI devices su**?

[Hannes]

You might try a higher sample rate and look what that can do for you.
I get lower latency on 48 than on 44.1Khz.

It was the Support that su*** plus i really dont like their products policy anymore....

Oh this is interesting! I thought it is vice versa: higher sample rate means more data that has to be processed so the CPU is busier and the latency will increase.

Nice recommendation that I have to try!

But recording in 48kHz does not work for me. Okay, technically there is no problem but my radio station accepts only 44.1kHz mp3s. Months back I sent in a mp3 with 48kHz that was not streamed by the server, it was skipped automatically. But if the latency decreases I will use Cross with 48kHz and record with 44.1kHz. Thanks for the hint j-kut!

No Prob Steve!

It uses your Processor a little more, but if you set it to the same buffersize you´ll automatically have lower latency by factor which you increase the Sample rate.

In your Case it would be:

2.2ms *44,1/48 =2.0....ms

Anyone please correct me if i´m wrong here.
