Restoration of old recordings

Sound Laundry looks interesting; how much does it cost? I need an
editor to restore 33 1/3 and 78 RPM recordings, mostly speech. Major
problem is scratches and pops, but recording has significant high
frequency noise and some rumble. In addition, there is a large volume
difference between interviewer and interviewee. Have purchase
"Adaptec Easy CD Creator Delux Edition v3.5," but do not hear any
significant improvement when the automatic restoration features are
used, nor can I hear much difference when the graphic equalizer is use
in Adaptec's Sound Editor program. My best results have been by first
adjusting the bass, trebble and loudness controls in my 28 year-old
preamp to produce the clearest speech before recording the wave file,
and then using the sound editor to view the file and cut out the sharp
discontinuities from scratches manually, 0.1 milliseconds at a time.
I'm looking for something faster and better.
Thanks! Norbert Thonnard
