Smoother SpyServer audio and better handling of slow servers: • Attempted fix for the audio drop-outs ("chuffing") some SpyServer connections had. • SpyServer now has a selectable sample rate and defaults to a lighter setting that streams cleanly on more connections. • If a server can't keep up in real time, Demod now tells you (and suggests switching to 8-bit, a lower rate, or another server) instead of just breaking up. • Stability improvements.
