native latency rates- what's yours?

Postby Mark Lemaire » Wed Nov 21, 2018 02:01

Just wondering what is the best likely throughput rate I might expect. My old system (Win XP, PMX 5.3, Mykerinos cards) I would get about 4.3ms. My current native system, I am getting about 55ms using 96k. This is with minimal processing.

What are others getting? Curious how good it can be.

I find it difficult to compare performance at different latencies between systems.
For native, ASIO buffers, processor load etc comes in to play.
How are you measuring your latency, is it roundtrip with converters or is it something else?
55ms seem a bit high. It s equivalent to 5280 samples at 96kHz.

For simplicity’s sake, I am simply reading to you the latency figures that are at the bottom of the screen when PMX is open.For purposes of comparison, what numbers are you getting?

That number at the bottom of the Pyramix screen will vary depending on a few factors, most notably the latency setting you've chosen for your ASIO interface (should you be using one), as well as the number of plug-ins in use, combined with their maximum Delay Compensation setting (Settings > Mixer > Mixer Settings).

For example, on my system, with a 96 kHz. four track project loaded, but with all plug-ins, of all types, removed, and with my ASIO connected RME Fireface set to its lowest latency setting of 96 samples, and with the Mixer's Automatic Delay Compensation turned off, I get 397 samples/4.1 ms.

Turn on Automatic Delay Compensation, and set it to the default 116 ms., that goes up to 493 samples/5.1 ms.

Change the Fireface's ASIO Latency to its maximum of 2048 samples, which I like to do when I'm editing, mixing or mastering, that climbs up to 4301 samples/44.8 ms.

Add in a reasonable selection of VS3 and VST plug-ins, that that gets up to 8817 samples/91.8 ms.

When I'm editing, mixing or mastering, I don't really care about Latency, and I'm happy for everything to be set to its maximum value, so that my machine is not stressed unduly. When I'm recording on location, if it's a session and I have a control room set up that is away from the performance space, I'll leave everything at max, because acoustic bleed doesn't interfere with my monitoring. If I'm recording a concert, and have to be located within the performance space, I might reduce the ASIO Latency to 128 samples, just so the bleed doesn't drive me crazy, but in all other cases, I prefer to keep the settings at their max. so that my laptop runs cooler, which when you're running a Bootcamped Mac with Windows 7, is an important consideration.

Frank

Thank you! That’s exactly the kind of information that I was looking for. I’ll give it a shot but I’m sitting down at the computer next time.

Pyramix 11.1.5 Hotfix
Native
Fireface UCX

Buffersize (latency) 128 for recording voices/post sync - I get clicks but no latency/delay to the artist in the studio. Clicks are on monitoring only.
Buffersize for mixing is at least 1024 samples. No issues whatsoever with mixing.
