Vinyl Record Production Gets a Much-Needed Tech Upgrade (engadget.com)
Ever wondered why you sometimes have to wait months after an album's launch to get the music on vinyl? It's not necessarily because the label hates vinyl -- in many cases, it's because the decades-old manufacturing process can't keep up with the format's resurgence. From a report on Engadget: Relief may be in sight for turntable fans, though. Viryl Technologies is producing a pressing machine system, WarmTone, that should drag vinyl production into the modern era. Much of WarmTone's improvement rests in its use of modern engineering. It's more reliable when producing the "pucks" that become records, makes it easier to switch out stampers (the negatives that press records) and sports a trimming/stacking system that can better handle large-scale production. Also, there's a raft of sensors -- the machine checks everything from pressure to temperature to timing, so companies will immediately know if something goes wrong.
Matter o'fact RIAA equalisation is different from just generalised compression. At the start of the LP era each record producer had its own equalisation scheme so what sounded good on your TT/AMP might sound awful on your neighbour's. So the Recording Industries Association of America (RIAA) tried, and mostly succeeded, in getting folks to use the equalisation scheme that they had so carefully decided on.
The idea was not so much to "make the mix sound good on vinyl" but to permit greater recording times (by decreasing the mean width of each groove), to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.
The power cutting-head could probably have coped, but the recorded track would have been wider (so less tracks would fit on the record) and you would have needed a highly compliant stylus, and much higher tracking weight to keep it in the groove (and so muc faster wear).
The RIAA equalisation curve (NOT compression) was a very neat answer to a difficult problem.
And sorry, but my carefully cared-for LPs have quite a different sound from CDs/DVDs - not necessarily better but different - somehow warmer and more immediate.
