- Just a silly question: does the 'good old' vinyl player permit
- frequencies as high as 20 kHz? As a rough estimation: suppose the
- needle reads a 78 rpm (as I said, good old) disc at 20 cm (8
- inch) from the center. A 20 kHz frequency then corresponds to a
- spatial resolution of 13 micrometer. My impression is that that
- signal is too small to be even detected by a mechanical needle.

- Am I missing something or does your thread miss any solid
- basis?
