I think that is a good way to do it electronically. I would use tones instead of music. The least amount of crosstalk will be at 1K so I'd use a 1K tone.billshurv wrote: ↑Sat Sep 08, 2018 8:47 pm
Random notes on alignment. The usual method of azimuth alignment is to play a vertically encoded track and adjust for a null. Of course most test tracks only have a 300Hz vertical track on them so this doesn't necessary help much and also doesn't address stylus azimuth, which gets critical for certain stylus shapes. But vertical adjusted for null and horizontal adjusted for max should give the same answer, so that certainly seems a good way for live adjustment electrically.
I don't think that is worth worrying about unless you plan on making your own test record. You just have to decide the record you are using is the truth. I think the most accurate test record currently available is Flo Kaufmann's Flokason Test Record.On a first read seems to have useful tests in for checking stylus azimuth but not sure it does anything for generator azimuth measuring.
The AES compendium was mentioned. I wrote this on DIY Audio but the AES publications should be subtitled "Weird, Wacky and Esoteric papers". All the important work was doe before the AES existed. All the good stuff is in the H.E Roys "Disc Recording and Reproduction" compendium. Shhh, no one knows about that book.
