we have another enhancement possibility available to us. WSJT-X could set the operating system/driver fader to 0 dB as well. This may cause some consternation amongst users who have tweaked the levels because we have said the best place for the WSJT-X slider is in the middle. Those who have done this are probably doing more harm than if they had tweaked the WSJT-X slider to get to 30 dB on background noise. Another option is that we could also switch the WSJT-X level control to actually change the o/s / driver fader but note the value is in the range 0.0 to 1.0 and I assume that 1.0 is 0 dB FS so maybe only attenuation is available. Related to this, I have never been sure if the operating system level is more than just digital manipulation of the 16-bit PCM stream. For example it could have access to a 24-bit sample stream at a high sample rate on the input side (for example my laptop is capable of 192 kHz 24-bit audio input) and therefore has more resolution available than a gain control on a 16-bit sample stream would have. 73 Bill G4WJS. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
