Dear @mijostyn : """
which will account for any wear and inaccuracies that the math won't account for. """
between those inaccuracies are the ones in the test record that is not a " perfect " recording.
With the " maths " ( vynil engine calculator. ) you don't have to spend money for more just inaccuracies and you can be sure that the calculator result will be around 95%+ of the real value that's more than enough for that resonance frequency value..
No one needs a test record for what the OP is looking for, the test record is inherent inaccurate. So, where is its big deal?. No sense at all but to each his own.
In the other side the OP ask for maths even that he already knew about the internet calculators.
