But who, except for a few audio fanatics, would be
interested, and worse, who'd have access to the
equipment to measure such effects?
Anybody who has the resources to digitze vinyl with a
computer, and a good test record, and some LPs that are
thought to be illustrative of the effect, has the
required equipment. Suitable software is available for
no charge.
And what method could be used to
try to separate the "bad" vibrations from the wanted
stylus movement?
The method of differences.
One hypothesis in that the record clamp will reduce vibrations. Take data
with and without the clamp.
Another hypothesis is that some record mat materials (say sorbothane) reduce
vibrations. Take data with and without the clamp.
As I mentioned...a clamp might influence things like bearing noise causing
subtle differences that are record vibrations.
The article you referenced indicated this problem is more one of vinyl
compliance
which might be better addressed by using a better material than vinyl
rather than trying to damp the problem.
Acrylic polymer maybe. Something less compliant but still moldable in fine
detail. Calling GE
.
