Stereo Tool

hello there,

we are having issues with sychronizing our fm transmitters.
We have our studio computer, which has audio going through stereotool, and stereotool also streams the audio towards 2 locations where our transmitters are.
On both of the sites of the transmitters we have internet and a computer with stereotool receiving the audio and sending it to the transmitter.
But the audio is not in sync - sometimes up to 30 sec of difference.
I was reading that we need a gps receiver if it's a SFN , but our transmitters are both on different frequencies. Do we still need a gps to make sure the signal is synced?
Thanks for the advice!

Best way to do that is with micrompx. Process audio at studio and send via micrompx to 2 micro mpx decoders , each one at each transmitter.
With that configuration you wil have all stereotool processing benefits and any issue with sync between 2 frequencies.

On the 2 transmitter site, do:
Into FM sound card tab,
Set Buffer size to suffcient size. For ex if your stream is 320Kbps, but 10 sec buffer size.
Enable Synchronize FM Signals with:
Relative Adjust 5.00%
Turbo 20.00%
Resampling quality 32

Now your transmitter should be synchrone. If you have systematically a delay you can adjst slowly Extra delay on one transmitter to have both synchronized
