For a long time I have encountered severe audio stuttering in VATSIM, to the point where ATIS messages are unintelligible and I can’t understand most ATC.
After testing everything on my end, I discovered that using tethered internet from my 4G mobile completely solved the issue. Therefore, the problem is with my ISP.
Using the WinMTR software, I found that the ‘fsd.connect.vatsim.net’ Automatic server address directed me to the USA-W server (I live in Australia), and some server/switch in LA and San Jose were giving me high rates of packet loss.
Testing the same address with my 4G mobile internet didn’t give me much packet loss at all, and slightly shorter ping times.
Further, testing the Amsterdam and German servers using my home internet was clear – zero packet loss, albeit high ping times as Europe is very far from Australia
I am faced with two solutions – either change my ISP or for there to be a workaround in vPilot to allow me to select the server, rather than the default Automatic.
