Fri 15 Feb 2008 at 01:17:44 EST Alan Bloom wrote I read years ago that speech processors like pre-emphasized audio (louder highs, quieter lows). And the heavier the processing the more pre-emphasis is optimum. Does anyone know if the K3 speech processor does that automatically?
-- Hi Alan, According to the Owner's manual, the K3 has ... 1. An RF speech processor which provides adjustable speech compression in dB (although it doesn't state the maximum compression). 2. 8-Band TX audio graphic EQ +/- 16 dB/octave. ... from the descriptions of these features I would "guess" that the answer to your question is, no it doesn't do that automatically. However, the good news is that the sort of emphasis and de-emphasis you describe can be accomplished manually via the equalizer. To "properly" do what you describe automatically would probably require factoring in your specific voice and microphone characteristics (probably by reciting a known phrase) and IMHO is way beyond the scope of what the K3 firmware should do. I think it would be better to perform this kind of processing via a PC sound card. That said, I believe several users have already requested the ability to save multiple user preferences. With such a capability you could tailor a few different equalizer profiles and (manually) provide a similar capability. All you would have to do is to select the matching EQ profile as you change compression. Hopefully this won't be the sort of thing that you will be changing frequently, and you will only have a few EQ profiles to choose from. 73, Gary KI4GGX K3 S/N TBD _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
