Cleaning of vinyl
There is a need to have old records
restored. There are two of us in the group POCM (Preserve Our Corps Memories) who have developed extraordinary
skills. Give us your record and we will squeeze every last bit of
phonic quality out of the vinyl.
Cleaning the vinyl
we use equipment from Nitty
Gritty. This piece of hardware has been recommended
by the United States Library of Congress as an excellent item for
cleaning "ickys" from a record. In fact, if you read their web site
carefully, you will find that even a new record might benefit from
a pass through this marvelous product. ("Oh, Sop, ye jest do ye

jam, dried beer, etc. but not physical damage to the vinyl. This
type of damage is dealt with another way.
Cleaning the resultant recorded
From this recording, a .wav file
is created. It is important that at no point is the phonic quality
lost by electronic compression. For example, an mp3 file at 192
bits/sec is considered true CD quality and a .wav file contains
more phonic data than that!
This file is then turned over to
the software expert. Any left over imperfections will be removed.
The details of this are probably not as exciting as the tail of
the skip removal technique but I assure you it is not magic. It
also is not simply having high powered software to do the trick.
One must know music and in this case, one must know drum corps music
as a snare hitting the drum can be interpreted by software to be
a click to be removed. A drum major clapping his hands may also
be interpreted as a noise to be removed. Drummers hitting their
sticks together definitely can sound like a click to be removed.
All along in this process there
are limits as to what can be done depending on how much damage has
been done to the original vinyl. An imperfection is a challenge
to be met and conquered. Sadly, not all imperfections can be conquered.
Rest assured that this is a labor
of love for both experts. The joy is in the result.
