Logging Latency & Jitter profile during a session - any chance?

General Discussion
1

JackTrip is now apparently measuring latency & jitter individually for all participants during a session. Is this data being logged anywhere & if so is there a possibility of retrieving these logs so that they may be displayed either locally or on the studio display? In recent two hour sessions of (typically) six players in the early evenings we have observed changes in connection quality which apparently coincide with ISP throttling of fibre connections - giving jitter in the order of >100ms. Being able to compare the connections for all players at different times of day might help us find a better time to play together.

We are not currently logging any of the jitter stats. Good idea, though!

Just in case you haven’t tried it already, JackTrip’s Audio Quality slider lets you set a limit on connection jitter. Of course, there is a limit to how much you can limit it before the audio gets completely garbled. But there may be a balance in there that works better for you than the “Auto” setting, when you ISP gets flaky.

Thanks Mike.

There are tools such as ThinkBroadband’s quality monitor (https://www.thinkbroadband.com/broadband/monitoring/quality) which flagged a severe problem on our drummer’s connection on our Tuesday night rehearsal slot, so we could use that individually and compare the results. I was just thinking that the Virtual Studio might already have relevant data for all participants in a session & present it conveniently. Maybe this is one for later!

That looks like a very useful tool! I often use mtr myself, but I’m more of a command line guy.

What did JackTrip’s latency indicator look like for your drummer during rehearsal? It should already detect and flag anyone with a bad connection. Was it not red and displaying a warning message?

Here is an example of what it may look like for someone who otherwise has a good setup, but is using Wi-Fi:

Thanks Mike - yes, JackTrip’s indicator was indeed showing something similar to your example (only the figures were much worse).

Our drummer had just upgraded to full fibre broadband so the results surprised me. Connection direct to the router (not wi-fi). When I investigated I soon discovered this has been an ongoing problem with the particular combination of fibre and ISP concerned and especially so on Tuesday evenings for some reason. Much earlier on the same day the connection had been showing excellent for the duration of the session.
