| Tech Note | This is What Became Of The Bettys Source. I cleaned up the interference
in the form of an annoying whine in the same manner as I did other Port
Chester shows (2/18,2/21,2/23,2/24). However, I used two different
programs to do so. For disks 1 and 2, I used Diamond Cut Audio
Restorations Tools Notch Filter, with a filter width of 0.03 to 0.04
octaves, centered on ~8000 Hz, or wherever the whine happened to be.
I used Sound Forge Noise Reduction Plugin, centering on the whine, for
disc 3. Why two different programs? I began work on this show about
a month ago. I recently purchased the DCART program after hearing it
being widely regarded as one of the best (affordable) programs out there
for cleaning up audio. Let your ears judge which is best if you can tell
the difference. I found the DCART notch filter to be the better tool for
the job, while the SFNR plugin is flexible enough to be used as a notch
filter.
I also realized long after I was into cleaning this show up that others
have done so before me on this particular show. I'd be interested in any
feedback as to how my show compares to other efforts! I used the
narrowest filters I could without going bonkers. In some sections of the
show the whine wandered quickly, forcing me to use lots of different
filters over a small portion of the show.
