Some measurements

[Goofball_star_dot_etal]

I just ran some "Samples from USB Turntables" through my old tool.

Results here:

Perhaps Arny or someone else could pass this information on to Knowzy as
I am not joining 'no forums'..

Thanks.

I am adding/have added some more files. For the first time I can clearly
distinguish
imperfections in the platter-pulley/test-disk from the slightly lower
rotational speed
of those in the belt.

This can be seen in the polat plots in /Grace, /Crosley
where the magnitudes of both effects are comparable. This is done by
tweaking the "platter speed" control which changes the rate at which the
plot wraps around.
