HD Vinyl - WTF?

Their main claims seem to be "louder than normal vinyl" and/or longer playing time with more uniform sound quality over the run. "Louder than normal vinyl" is mostly a non-issue. I can already cut discs louder than anyone can play back. The problem is that the system is rate-limited; the stylus can only move back and forth so fast. So the amount of excursion you can get on a low note is MUCH wider than the amount you can get on a high note. Sure, you can cut at half speed in order to get wider excursions at higher frequencies, but you get discs that nobody can play back because their playback stylus can't follow the groove accurately. Also, looking at the stylus and groove profiles they favour, the stylus will not be able to get past the dirt in the groove without reproducing it along with the required signal. It'll be the same problem as the laser pickups have. I don't see this being particularly worse than normal playback. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Cutting with wider excursion doesn't necessarily give you any added distortion. The thing about the LP is that, unlike with the CD, there is no actual reference level and although there are hard limits on excursion due to the design of the cutter, there are many other limits that prevent you from coming near them most of the time. In most cases it's the playback system that limits things; there is no reason to cut a disc that can't be played back without skipping. But I would be willing to cut a lot hotter transients on a disc intended for the audiophile market than for one intended for playback on jukeboxes. --scott -- "C'est un Nagra.

Scott is saying that he can get 'higher up' cutting vinyl (presumably versus the averagely good)... Nothing to do with flat tops or average envelope levels sorry thek. geoff |

You can think of the LP as being slew-limited. It's not like regular analogue media. You have more headroom at low frequencies than at high ones because the limitation isn't -total excursion- but how fast you can move the stylus. Nothing to do with flat tops or average envelope levels sorry thek. The cool thing with the LP is that you can have peaks that far exceed the average level as long as you time them right so that the peaks on adjacent grooves don't hit one another. So aggressive limiting doesn't actually make anything any louder (although a little light limiting can make discs easier to track). --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

geoff, Scott:
But loudness is perceived by average levels, not peak levels. |

Because it's not total excursion that limits your cutting levels. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
