Turnable database with TimeLine

Nothing to say except it was bang on accurate, with the laser beam hitting a wall 8 feet away. I did not try a wide variety of music, and I did not persevere for very long once I felt the point was made. Perhaps in 10 minutes of observation there might have been some deviation; I can't say either way. I think I watched the blinking light for 2-3 minutes at most. Then I fell into a "deep sleep" and did whatever my wife told me to do for a week. Eventually, I snapped out of it.

If you're asking whether I can post a video, the answer is that I lacked such a capability at the time, not to mention that I had no such idea, either. I can probably re-borrow the Timeline if inquiring minds want to know.

The real question is are these very, very small speed changes AUDIBLE!

I seriously doubt it!

Tape recorders and cutting equipment does not have perfect speed in the first place.

Many audiophiles like to split hairs with theory that makes no difference in real life. This is just golden ear BS!

8 feet to the wall, that is a tough test.

I understand your skepticism, but would argue that these micro speed changes are indeed audible.
Sure we have tape machine speed instability along with eccentricity problems. That said, speed changes due to stylus drag, which is where this thread has kinda coalesced, are fundamentally different in nature. This because the music itself causes it. This results in a subtle smearing and bending of the notes. A general softening of the soundscape. The effect can be " nice " but it is not what was laid down on the record.

I would like to again offer my Timeline Calculator Excel file for anyone who would like to try it out. You enter the distance to the wall and the laser deviation per revolution and it gives you the circumference of the virtual circle that the laser travels, the speed error of your platter in percent, the RPM your platter is off by, and the actual RPM of your platter. It can also tell you how many Hz a given frequency is off by.

Ketchup, I'll take you up on your offer. How do I get my email to you so that you can PM me? Thanks.
