Ratings & Reviews
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.
