tl;dr: Initial tests have worked for both Mac and Windows
I am eager to get JamKazam (or any online real-time music collaboration tool) working and document it so others can do the same for themselves. Here are my goals:
- Get JamKazam working on and document the process for both macOS and Windows
- Successfully play string quartets with my friends online
- Successfully stage online performances with remote musicians and remote audience members
- Successfully tie JamKazam (or another music collaboration tool) into Google Meet, Zoom, or other video conferencing tool
I had my first brief successful JamKazam session last night! With this post, I have made major headway on Goal #1 above.
Mac to Mac Test #1: Success!
I am in Portland, Oregon, and my friend is in Idaho. For our first test, we used this combination:
| Test #1 | Me | Friend |
| Computer | MacBook Pro | Desktop Mac |
| Network Speed (download/upload) | 500Mbps/802Mbps | 222Mbps/10Mbps |
| Microphone | Plantronics wired USB Headset | Blue Yeti USB Mic |
| Headphones | Plantronics wired USB Headset | Headphones plugged into Mac audio jack |
| Latency | 10.9ms (yellow) Sample Rate: Match Frame Size:1 |
I heard a slight echo in my own voice (like I was in a hallway or bathroom), but it wasn’t disruptive. My friend heard no such echo. We brought up video and were able to see each other with no significant delay between sound and video.
We first tried clapping together. I counted, “1-2-3-4,” and then we started clapping. It was satisfactorily close to unison. I picked up intermittent static when I talked, but my friend heard no such noise.
Mac to Mac Test #2: Success!
Since I wanted to try playing a musical instrument, I needed to switch to a different microphone. A headset mic would do fine for singing, but not for acoustic instruments. I own a Yeti Blue USB mic (same as my friend’s), so I plugged it in.
| Test #2 | Me | Friend |
| Computer | MacBook Pro | Desktop Mac |
| Network Speed (download/upload) | 473Mbps/802Mbps | 222Mbps/10Mbps |
| Microphone | Blue Yeti USB Mic | Blue Yeti USB Mic |
| Headphones | Plantronics wired USB Headset | Headphones plugged into Mac audio jack |
| Latency | 9.77ms (green) Sample Rate: Match Frame Size: 1 |
The first thing I found was that JamKazam does not seem to let you change equipment mid-session, so I ended our jam session, reconfigured JamKazam to use my USB mic, started a new session, invited my friend, and we connected.
Again, sound and video worked fine, although I did still heard some intermittent static when I spoke (which my friend did not hear). It wasn’t terrible or untenable, but it was there. I suspect interference from my numerous electronic gadgets and wireless devices.
I invited my friend to play, so she pulled out her viola, as did I, and we were able to play duets together effortlessly. We started with slower music, so I suggested a faster piece which would have tighter timing demands. Success!
Mac to Windows Test – Success!
Update: My first attempt with running JamKazam on Windows last night was a failure, but I just now ran a test and it was a rousing success. Here was my configuration:
| Test #3 | Me | Friend |
| Computer | Windows 10 Desktop | Desktop Mac |
| Network Speed (download/upload) | 600Mbps/930Mbps | 222Mbps/10Mbps |
| Microphone | Blue Yeti USB Mic | Blue Yeti USB Mic |
| Headphones | Headphones plugged into Blue Yeti Mic | Headphones plugged into Mac audio jack |
| Latency | 19ms (yellow) | 7.77ms (green) |
Not only was my last test running JamKazam on Windows successful, but I experienced none of the static I had last night.
My friend mentioned she experimented plugging her headphones directly into her Mac versus into the jack on her Blue Yeti USB mic. She found she had some static when plugging her headphones into the Mac, but not into the mic.
Testing JamKazam with Google Meet: Fail
We returned to the Mac to Mac configuration for my last test, which was to see whether I could share my JamKazam session with Google Meet.

Why do I want to do this? I host regular online karaoke parties using Google Meet. During those parties, only one person can perform while the others all listen while muted. I would love to be able to sing or play duets with a friend and have my Google Meet attendees see and hear us. Also, my understanding is that although you can stage online performances using JamKazam, I believe it requires all audience members to have a JamKazam account. Tying JamKazam into Google Meet (or Zoom, etc.) would skip that requirement.
So we repeated the setup #2 above, and on my Mac I launched Google Meet and had a second person connect into my Google meeting. I shared my desktop and my second friend was able to see my JamKazam video, but they could not hear my friend in Idaho.
I suspect there may be a permissions setting I need to set to allow my Mac computer sound to be shared on Google Meet. I will continue to investigate and test.
In future posts I hope to connect with different people, getting Windows working (done), and give step-by-step instructions for creating a jam session and inviting friends.
Stay Tuned!
