LATENCY, mostly TOTAL LATENCY |

TOTAL LATENCY, about
We begin with some serious fun - for people hit by latency
LATENCY demonstration in SESSION - by distinct clapping, tapping on microphone or whatever. 60-70 bpm:
1. One person start - and keep on, steady.
After some seconds all other try to follow excactly. One by one, maybe. Whatever.
2. One person start ...
Only one other person follow ...
-
JamKazam terms:
20 milliseconds and below is called GOOD and the dot is GREEN
Between 20 and 35 is called FAIR and the dot is YELLOW
Between 35 and 50 is called POOR and the dot is RED
50 and over is called UNACCEPTABLE and the dot is RED
-
10 milliseconds TOTAL LATENCY between (two) people is like playing 3,5 meters apart from each other. Very few people can hear/notice such low latency as 10 ms.
20 milliseconds is like 7 meter apart. All average human beings can hear/notice 20 milliseconds delay - under best condition.
50 milliseconds is like 17,5 meter apart.
100 milliseconds is like 35 meter apart.
-
Playing together in "real" real time is impossible
There will always be some latency, delay - from audio interface and from the internet connection.
Audio interface latency can be as low as 2 milliseconds - depending on quality and so.
Internet latency can be as low as 3 milliseconds, depending on quality - and distance between people, quantity, so to speak.
--- VERY important is the so called PING - the "answer time" from PC to internet provider and back,
I have 13 ms PING, for example. It can be so low as 2 ms.
Example: 2 x audio interface = 4 milliseconds.
1 x internet connection = 3 milliseconds
TOTAL LATENCY = 7 milliseconds
-
The best connection I have is from one of my computers to another of my computers on the same router/LAN. Two accounts is needed for that, of course. The TOTAL LATENCY is around 10 milliseconds.
My second best connection is with a person 100 kilometers away. The TOTAL LATENCY is 18 milliseconds.
To people in Australia (I am in Denmark) the TOTAL LATENCY is 200-300 milliseconds - that is only for very, very, very slowly and loose singing.
To USAs eastcoast it is usually 75-80.
To Californien 110-130
Thailand around 150.
My relatively best connection is with one 2.000 kilometer away in Norway. The TOTAL LATENCY is about 27 milliseconds.
Latency in my audio interface is by the way 4.2 milliseconds.
-
Having the same internetprovider gives usually lower internet latency.
Maybe 5 milliseconds in most cases.
Maybe 20 in some cases.
What is the usual internet latency between for example?
1. Portland, New Hampsh i re and New York
2. Kansas City and Denver
3. Seattle and Chicago
4. San Antonio and Panama City
4. Dallas and Los Angeles
6. Jacksonville and Miami
7. New York to Kansas = 32 ms - as one example. audio gear included
Other examples is very welcome
- from all over the world
Not audio interface latency included, please
- only internet latency

No Input Signal to Jamkazam application |

Unable to get any audio signal to show on channel 1 or 2 on the JamKazam (JK) app...
Using a MacBook Pro (Mojave 10.14.6)...
Connected a M-Audio (m-track), the JK inputs/outputs show as a M-Audio, latency reads 10.2ms (yellow), can hear output audio (jamtracks) no problem....but no visual reading on the JK app seeing any audio on ch 1 or 2 (I can see input audio to the M-Audio, but it is not being sent to the JK app).
Also tried connecting Presonus Studiolive 24.4.2 (via firewire), the JK input/output configuration shows the Presonus Firestudio, latency reads 9.8ms (green), same as M-Audio... cannot see the audio input from the Studiolive.
Appreciate any advise...THX Jim.

Video is not recording |

Hi,
we did some Tests and recorded today our Audio. We had to record Video with our Phones to have it.
Because (both mac Catalina and April Update of jk client) the Video does not record. The record stops after some seconds. Access to te Cam is allowed in the security settings of MacOS.
Is ist a bug or a feature? Any advice on this?

30 minutes to load app |

Peter from Jamkazam referred my problem to the forum. I am new to Jamkazam and the forum. Any first opening of the app creates the 30 minute delay after powering my Samsung tablet with Windows 10. It stalls on Windows Installer: Preparing to install. After 30 minutes, I get Windows Installer: Install server not responding. The options are retry or cancel. Retry starts another 30 minute hold. Canceling allows the app to open. Once the app opens, using ethernet cord with wifi disabled, closing and subsequent opening of the app works without delay. Enabling wifi at any point creates a 30 minute delay in opening again. I tried a clean boot with no effect. Let me know what you think. Thanks. Stay safe.
Larry
