Motu 16a

[ShiftStudios]

These new AVB interfaces are amazing. If you are recording with a Mac and have Yosemite, I highly recommend checking this out. Previously on PT12 with firewire device, I was getting 20 tracks stable and noise free at 256 samples 48khz. With the MOTU 16A, I just did a benchmark test, 24 tracks @ 96khz with setting of 32 samples, less than 3ms round trip and nary an issue. Call me impressed in the AVB protocol. :)

How did you measure the round trip latency?

Hi Amack,

Not the most accurate method, but I use the Logic Pro X audio interface settings panel. Probably not 100% accurate. But I have always used that for my round trip reading for all my interfaces because at least it's consistent. :)

If I record x tracks without pops and crackling, I consider it a pass, and I then use the setting readouts. Whether or not it's 100% accurate does not change the fact that this interface, through AVB, is measurably better than firewire interfaces.

I'd be happy to use whatever methods you guys use to provide some useful measurements. I'm extremely excited these AVB interfaces and their possibilities. The fact alone that I can get 128 channels in and 128 channels out simultaneously with AVB or thunderbolt, is amazing!

Just wanted to share my experiences. Happy to do some examples for people. :)

Hi ShiftStudios,

Thanks for sharing - that does sound like an awesome device. And at <1/3 the price of HD_IO, it sounds like the better performer (though its hard to tell because, unlike Motu, Avid apparently doesn't provide any real specs for the HD_IO).

How does it work on your PC?

Are you using Logic Pro for recording and mixing, or just recording?

ProTools Vanilla or HD will only go to buffer 32/64 at 44.1/96k

RTL will be A/D +(2X buffer)/SampleRate + D/A + any Thunderbolt overhead

MrMiller from MOTU has a lot of posts on this starting here - Somewhere in that thread there is an update from him about where they ended up. Great interfaces for sure but I would not totally trust what Logic says and sadly the Pro Tools answer may be different...

Audio over Ethernet is amazing!

Hi propower,

You are right, it was 64, so apologies for that, the latency time is still correct though. :) As I told Amack in my last post, the test I ran last night proved a perceivable improvement to me. :)

Cheers!

Hi Amack,

I only used Logic Pro for the test, I generally use Pro Tools for all my record/mixing. :)

In regards to real world scenario I did the following last night:

45 tracks, lots of heavy plugins (H-Reverb, SSLChannel, RVerb, iZotope oZone 6 Advanced. Created 2 x stereo and 7 x mono Audio, but input, fed output from drum tracks to busses, armed and hit record/play. At 64 samples there was no perceivable latency in the drum tracks being recorded against the tracks playing and being recorded, not a stutter or crackle either. This was not possible previously for me, so it's definitely a marked improvement. :)

Cheers.

Which version of Pro Tools did you use for this test? You used a Mac right? How long was your recording? What bit depth, sample rate, and buffer size did you use? What did Pro Tools show for the "System Delay" (in "Session Setup")

ShiftStudios,

Here's a simple procedure to measure DAW system audio Round Trip Latency (RTL), DAW RTL compensation error, and audio interface Direct Monitoring Latency (DML) http://duc.avid.com/showthread.php?t=368814. Although some (like guitardom and mesaone) may still disagree, I believe that propower, who apparently has a much better understanding of the issue, considers it to be effective (http://duc.avid.com/showpost.php?p=2267009&postcount=67).

Please let me know if you have any questions about the procedure or the posted results. I and likely many others would be interested in seeing your test results - especially in light of this post (which I no longer have “access” to) which suggests RTL latency compensation errors now occur with “HD native cards” (http://duc.avid.com/showpost.php?p=2269524&postcount=85).

Thanks!

Why do you keep bringing me up? Its not my fault you cant understand that track count does not affect latency among other ridiculous things you claim and some of us have to call you on it in order to keep you from telling people like its some sort of fact. You should be able to take hint of this by the way people keep stonewalling you in threads.
