[Lowfer] Re: Sound card measurements

[Lyle Koehler]

I followed Alberto's suggestion and added the schematics for the all-pass
filter to the photos section of the Yahoo soft_radio group at
http://groups.yahoo.com/group/soft_radio/. My Excel spreadsheet calculation
for 1st and 2nd order filters is in the files section. Thanks for the
suggestion, Alberto. It was easier than creating a new web page!

For those who haven't tried Alberto's SDRadio software, it is available at
