This is exactly the kind of comment which I need. Thank you. There are certainly gaps in my knowledge. I was attempting to avoid real-time audio file format conversions assuming that the batch conversion in Audacity would be of higher quality. I used the Virtual Audio Cable control panel to specify the format parameters at both the input and the output of the "cable" in an attempt to avoid such conversions. I would be glad to email any of the audio files to anyone interested. The 11 Khz files are just over 8 megs and are too large for posting on my "free" web page. Perhaps I am "straining at gnats and swallowing camels." Wes, WZ7I
