Having trouble getting acceptable latency

This is Jack. I have been a member for several months. I have read lots of info and have tried several set up variations. I’m still not getting decent latency. First of all, I am using wired ethernet. My only available connection is not fiber. I’m using an external audio device. I’m using wired headphones. I have purchased and am using a new audio interface. ( Focusrite Scarlett Solo 4th generation). and I have tried assorted settings. (Perhaps you could enlighten me on what settings you feel are optimal). My desired reason for using JackTrip would be to play in a jam situation or teaching a class. Other than the lack of fiber internet, I should have it all. Is it doable without fiber internet?

Hi Jack and welcome back. I did not read anything in your post about the distance between you and others to the studio server where you are connecting. Latency has more to do with distance than any of the other details you have mentioned above, so a distance of more than 300 miles to the server by anyone connected will cause more latency.

And I want to add that even with fiber, we face the speed of light limitation.

Fiber Internet offers latency that is 4 to 10 times better than any other type of connection. It’s nearly impossible to get below 25 milliseconds (the typical threshold often referenced for live music performance) without it. Depending on what you are trying to do, it may be required.

Hi Synthia,
I appreciate you getting back to me. I am a newbie here. I really want to get this to work. As far as your question: So far, I have just been testing my latency by opening up my studio, following the basic guidelines, connecting a guitar or microphone, connecting to San Francisco (I am in Oakland)and observing the latency. I’m not connecting with anyone else. My latency will show up as high as 300 ms. I know this is a pretty basic, uninformed question. But, do I have to be connected with someone, regardless of their distance, to get an accurate latency reading? Much thanks. Jack

Thanks, Mike. I will be doing live jams and one on one music lessons, with a desire to play over a track at the same time. Sounds like I might have to wait for fiber connection.

Hi Jack,

Thank you for your question. You should be able to get an idea of the
latency with just your connection to the Virtual Studio in San Francisco
from your location in Oakland, probably less than 20 miles away.

The high latency you are reporting makes me wonder: by any chance is
your internet service connected to a mesh network?

I looked up the definition of mesh network. I don’t believe I have that. I do have 2 neighbors in my apartment building doing wi-fi off of my network.

Additional users on your network, whether WIFI or ethernet, can impact
the availability of bandwidth and amount of latency.

Regarding mesh networks: very popular in the Bay Area, the providers
advertise the low cost and wide service area of a mesh network. They can
give you ethernet inside the building but outside is connected to a WIFI
mesh in order to serve a larger number of users and lower cost to each.

Also Jack, the latency fluctuations that you have reported in previous
posts is typical of WIFI’s dips and spikes of data flow. If you and two
additional people are using your WIFI, it is not unusual to have high
and erratic latency readings.

Which begs the question: are you using wired Ethernet cable from your computer to the router? You can have an Ethernet connection without it being connected to a fiber optic network.

Thanks so much for getting in touch again. To answer your last question: I am using an Ethernet cable from my computer to the router.
I will do a little experiment and have my neighbors turn off their computers as I test Jack trip.

Great idea Jack. Please let us know your findings.

One last tip is to disable Wifi on the router and the computer as well as Bluetooth on the computer. wireless devices tend to compete for computer resources and add varying amounts of instability and latency in the process.

Standing by…

Who is your Internet provider, and what type of connection do you have (Cable, DSL, etc)? 300ms is insane. Is that the number you see reported by JackTrip’s latency indicators? There are plenty of providers in the bay area that can consistently get you under 35ms. You can search for Fiber Internet availability via this link, but you can search on that website for other providers as well.

Checking in with you Jack, we’re so glad you’re here. I have been thinking about how you want to use JackTrip and that reducing latency is a critical need for you.

Please let us know if you have had a chance to test JackTrip again without your neighbors’ connections, or other ways to reduce the latency you are experiencing.

Hi Synthia!
Thank you so much for getting back to me. I did indeed check with turning off my two neighbors Wi-Fi. Sorry to say, nothing changed. Still coming in at around 300 MS. I think I might just let it go for right now. I will get back in touch with you after I get a fiber connection. Much appreciation.

ok, understood. The latency reported here indicates that your internet
service could be going to WIFI outside the building. And there might be
non-fiber provider options that are not using WIFI outside the building
and offer reduced latency without the big jump to fiber.

Good luck with everything Jack, and thanks for sharing - we’re here if
you have any other questions or concerns.
