Zero latency: no added delay, safe on front-of-house and monitor mixes

Version history

2.1.9 - Fix: after every instance of this plug-in was removed, adding a new one and opening its window could close the host (DAW / SuperRack / Signal Rack). It came with the online-update version; please update every computer. Sound and features are unchanged
2.1.8 - Online updates: when T Sound Man releases a new version, the plug-in offers it when its window opens and installs it in one click (it downloads and checks the installer itself). Mac installers are signed with an Apple Developer ID and notarized by Apple, so they open without a warning. Sound and features are unchanged

2.1.7 - About a third less CPU with NOISE off (the noise-reduction filters run only the part that keeps learning the room); the sound is unchanged sample for sample. Switching NOISE on warms the filters for 0.15 s before the fade, without a click. Steadier activation: at most 4.5 s per try to reach the licence server, closing during an activation never hangs, and every legacy key works
2.1.6 - Activation works on every network: the licence server is reached through tsoundman.com first (fixes Could not connect to the licence server), and stray characters around the key are cleaned off. The Licence window has Paste and Load key file buttons (pick a file with the key, no typing or pasting), and activation messages are always on top
2.1.5 - New howl handling: a howl that comes back is caught at once, notches let go faster once the howl is gone, sub-Hz frequency accuracy, and half the false cuts on the voice compared with 2.0.1
2.0.1 - Fixed a robotic buzz on stereo tracks (heard while a notch was active, mostly in the low band); new howl detector, faster and more accurate across the whole range
2.0.0 - New feedback detection engine, shared with FeedbackKiller Plus+ 8CH
