Version history

2.1.9 - Online updates: when T Sound Man releases a new version, the program offers it 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
2.1.8 - When the audio driver stops by itself (an ASIO reset, for example) audio comes back within 2 s; before, it stayed off until the interface was chosen again in Settings

Show all (7)

2.1.7 - Uses every CPU core: the 8 channels are shared out over the cores, about half the CPU, the same sound sample for sample, and lighter again with NOISE off. 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
2.1.5 - The Feedback Killer 2.1.5 detection engine: a returning howl is caught at once, notches let go faster, fewer false cuts on the voice
2.0.1 - New howl detector, faster and more accurate across the whole range (better with several treble howls at once, ignores clipping harmonics, notches re-centre on the howl)
2.0.0 - New engine shared with the plug-in, 48 kHz default sample rate, Remote app support
