System with high latency but low jitter

General Discussion

Hi All,

I am investigating a setup to which I cannot seem to find the answers I am looking for yet so I am hoping to get some help here.

My goal is to have a system where 3-10 raspberryPI’s are connected over Wifi to one receiving computer (PC running windows) all being on the same LAN without internet.
I want to use the Rpi’s as “wireless microphones” to send their input (an I2S microphone) tot the PC where I want to multirack record all channels.

My question is; for this setup I don’t care too much about latency (can even be 1 second) but I care very much about synchronization, I want every channel to be within 1ms compared to the rest.
Is it possible to configure a setup in this way?

Many thanks in advance!
Kees

Hi Kees, yes I think you can by using a fixed number for the “-q” command line parameter. For example, “-bufstrategy 3 -q100” would yield a 100ms jitter buffer.

Hi Mike, thank you for you reply.
Can anything be said about the sync between the different senders? Or will it be dependant on the sync of the clocks of each device?

Thanks

JackTrip does not perform any clock syncing.
