* bug fix: the server welcome message may appear twice if the server list was double clicked
TODO mixer faders linear -> log gain is better
TODO offer the Jamulus ASIO settingspanel in case of an ASIO ERROR to fix, e.g., incorrect sample rate (https://sourceforge.net/p/llcon/discussion/533517/thread/777663cf94/#035f)
TODO client: larger sound card buffers are managed by conversion buffer, not in processintern for loop (note iSndCrdFrameSizeFactor!)
maybe let the use select all possible sound card buffer sizes, this should solve Ticket #53
TODO mixer faders linear -> log gain is better: CalcFaderGain() -> x = -50:1:0; plot(x, (10 .^ (x / 10)))
TODO offer the Jamulus ASIO settingspanel in case of an ASIO ERROR to fix, e.g., incorrect sample rate (https://sourceforge.net/p/llcon/discussion/533517/thread/777663cf94/#035f)
TODO auto jitter buffer performance not good at 64 samples frame size -> to be checked again
TODO for different frame sizes (64/128) the start value of 6 for the jitter buffer might be too low
