If 8 is the maximum that a connection can support - then the maximum in a session is 8, of course.
And ALL those 8 must have a connection that support 8.
Maybe some connections can support for example 16 or 32 - who knows?
But it will still require that all the other 15 or 31 also can do the same.
I have NEVER been in a session with more than 8 that actually sounded well - for more than a few seconds.
9 = unpleasant
10 = awful
11 = disguisting
12 = where is the leave button?
13 = I can not breathe
14 = tell them I love them
15 = ???
Hi. I am working with a chorus of around 35 people before COVID hit. We are trying to get as many people to use JamKazam simultaneously as possible. We have figured out that each additional PC that logs into a session adds about 325 Kilobit/second of data for both sending and receiving for everyone in the session. So if there are 10 participants, there will be about 3.25 MegaBits/second data sending and receiving for everyone. This makes it clear that it is important that everyone in the session has good high-bandwidth service from their internet service provider. This can be checked by each person by running an internet speed test with their browser. We use this one: https://www.speedtest.net/ . Here, pay attention to the UPLOAD Mbps result. This is typically the bottle neck in your internet connection. This has to be greater than the bandwidth generated by all the people in the session. If it is not greater, you are going to have a bad session!
Another useful thing we found is that there is an option in JamKazam to reduce the bandwidth of the audio data that is being sent out from a participant in the session. Click the "Manage" tab in the upper left corner, then click on "Audio Settings" and then "Audio Booster". In the window that pops up, you will see a setting called "Maximum Outgoing Music Bitrate". During an active session, this setting can be reduced to 128 Kbps. This greatly reduces the bandwidth sent out by the participant. We have had all our participants do this and it helps keeping the total bandwidth of the session down. It does not seem to greatly degrade the audio quality. So far, we have been able to have up to 13 participants in a session with good results. We are hoping to add more and see how it holds up. Good luck, Hans.
