For the last few days I’ve been attacking latency in the signal processing chain as a prelude to adding transmit support.
I’ve switched over to WASAPI http://msdn.microsoft.com/en-us/library/windows/desktop/dd371455(v=vs.85).aspx for VISTA / W7 / W8 and also made ‘tweaks’ to the DSP code.
I now hear the CW dots & dashes as fast as I see them on the waterfall, even when the waterfall is running at 100 lines / second.
