I know, thanks. It’s wrong all the time except for only two moments. Plus as you then go on to state - it’s wrong all the time because of skating or “sway". And it’s wrong a lot of the time if the record is decentered. And it bounces in the vertical domain, which is why tracking angle is so critical, not just on a static but on a dynamic basis because needle bounce matters. And if I’m trying to cancel common 6kHz hiss or flutter a sample or two at 96kHz makes a huge difference — it’s the coarseness of the medium in general that leads many to think these things are insignificant, but attention to this level of detail can yield results. > On May 6, 2015, at 4:01 PM, Goran Finnberg [log in to unmask] <[log in to unmask]> wrote: > > Jamie Howarth: > >> Correct, and I'm talking about phase because the two grooves are never perfectly perpendicular. > > The cutter moves the cutting head in a straight line. > > Most replay of disks uses an angled arm that normally only shows zero error at two points on the disk. > > This error is so small that trying to correct for it makes very little sense to me. > > Replaying the disk using a straight line tonearm removes this very small error completely. > > Having a few degrees at most tracking error due to playing with an angled tonearm that upsets the perpendicularity of the disk left/right track is still so small that this error when summed is of no concern to me. > > Most cartridges has greater errors than this ime. > > -- > Best regards, > > Goran Finnberg > The Mastering Room AB > Goteborg > Sweden > > E-mail: [log in to unmask] > > Learn from the mistakes of others, you can never live long enough to > make them all yourself. - John Luther > > (\__/) > (='.'=) > (")_(") Smurfen:RIP
