Rich said: intelligibility is concentrated around 1-2K Hz. Yes?
I think so. If my failing memory serves, early Bell Labs work found that 300 - 3000 Hz was the minimum- width audio band which preserved intelligibility and allowed the speaker to be recognized. That became the basis of the A/D converters which in turn fed the T-series [T-1, T-2 etc] of digital transmission systems for the telephone network. On the other hand, much of this thread seems to be about speech fidelity [Does it sound Great?] as opposed to intelligibility [Can I copy it?] Eric VA7DZ -- "Democracy depends on well-informed voters; absent that, it is all mud flowing down hill." --Charles Harpole -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
