It was discernible by some listeners throughout certain recordings but a quiet passage followed by a loud sound would allow anyone to hear a faint pre-echo of the loud sound occurring 1. Pre- and post-echo can be avoided by the use of direct metal mastering. The first LP records introduced used fixed pitch grooves just like their 78 predecessors. The use of magnetic tape for the production of the master recordings allowed the introduction of variable pitch grooves. The magnetic tape reproducer used to transfer the recording to the master disc was equipped with an auxiliary playback head positioned ahead of the main head by a distance equal to one revolution of the disc.
The sole purpose of this head was to monitor the amplitude of the recording. If the sound level from both the auxiliary and main magnetic heads was loud, the cutting head on the disc recording lathe was driven at its normal speed. However, if the sound level from both magnetic heads was quieter, then the disc cutting head could be driven at a lower speed reducing the groove pitch with no danger of the adjacent grooves colliding with each other.
The playing time of the disc was therefore increased by an amount dependent on the duration of quieter passages. The record manufacturers had also realised that by reducing the amplitude of the lower frequencies recorded in the groove, it was possible to decrease the spacing between the grooves and further increase the playing time.
These low frequencies were then restored to their original level on playback. Furthermore, if the amplitude of the high frequencies was artificially boosted on recording the disc and then subsequently reduced to their original level on playback, the noise introduced by the disc would be reduced by a similar amount.
This gave rise to an equalization frequency response applied during record coupled with an inverse of the response applied on playback. Each disc manufacturer applied their own version of an equalization curve mostly because each manufacturer's equalization curve was protected by interlocking patents.
Low-end reproduction equipment applied a compromise playback equalization that reproduced most discs reasonably well. However, amplifiers for audiophile equipment were equipped with an equalization selector with a position for most, if not all, disc manufacturers. The net effect of equalization is to allow longer playing time and lower background noise while maintaining full fidelity of music or other content.
Consequently, both low-quality and audiophile reproducers alike could replay any recording with the correct equalization. There are two versions of the reproduction RIAA equalization curve. The first, is simply the inverse of the recording curve designed for cheaper equipment using crystal or ceramic reproduction cartridges.
The second curve is intended for equipment fitted with magnetic reproduction cartridges where the output voltage is dependent on the frequency of the recorded signal the voltage output is directly proportional to the frequency of the recorded signal; that is: the voltage doubles as the recorded frequency doubles.
The audio quality of LPs has increased greatly since their inception. While early LP recordings were monophonic , stereophony had been demonstrated in and Alan Blumlein had patented Stereophonic sound in Unsuccessful attempts were made to create stereophonic records starting in the s, including Emory Cook 's "binaural" LPs using two precisely spaced tracks on the record one track for each channel which had to be played with two monaural pick-ups on a tuning-fork-shaped tonearm.
The modern system ultimately released by Audio Fidelity Records in November uses two modulation angles, equal and opposite 45 degrees from vertical and so perpendicular to each other. It can also be thought of as using traditional horizontal modulation for the sum of left and right channels mono , making it essentially compatible with simple mono recordings, and vertical-plane modulation for the difference of the two channels.
The composition of vinyl used to press records a blend of polyvinyl chloride and polyvinyl acetate has varied considerably over the years. Virgin vinyl is preferred, but during the s energy crisis , it became commonplace to use recycled vinyl.
Sound quality suffered, with increased ticks, pops, and other surface noises. Records in different novelty shapes have also been produced. Many critics have expressed skepticism regarding the cost and quality of HD records.
The audio engineering software was created with mastering engineers Scott Hull and Darcy Proper, a four-time Grammy winner. The demonstration offered the first simulations of what HD Vinyl records are likely to sound like, ahead of actual HD vinyl physical record production. Loibl discussed the Perfect Groove software at a presentation titled "Vinyl 4. Disc jockeys or DJs in clubs still frequently use vinyl records, as cueing tracks from cassette tapes is too slow and CDs did not allow creative playback options until The skill came in subtly matching beats or instruments from one song to the next, providing a consistent dance tempo.
DJs also made occasional announcements and chatted on the side with patrons while songs were playing to take requests, similar to what radio disc jockeys have been doing since the s. From Wikipedia, the free encyclopedia. This article is about vinyl records. For music albums in general, see Album. For other uses, see Long Play disambiguation.

Basic to advanced knowledge of the alphabet. This will come in handy when you need to alphabetize by group name. If you need help in this department, consult your local kindergarten teacher. Some knowledge of musical genres and where bands fall into them. This can become difficult if you are organizing records you've never listened to, in which case consult the internet. Led Zeppelin vs. Herbie Hancock. What genre is each? Lots of time This is the first step in breaking down a large collection into smaller more manageable groups.
For the sake saving space it is important to keep your genres somewhat broad. The general rule of five I use breaks down into: -Rock -Jazz -Classical -Bluegrass -Crap I will never listen to Of course if you have a substantial amount of country, hip hop, or electronica records, feel free to make them into their own group. Some people see these groups as being too broad, as Rock can encompass so many things, but for my collection it works just fine.
Once you have divided into genres it is time to take those genres and organize them by letter. Reply 8 years ago on Introduction. One of the most overlooked items that every household has, is PERFECT for removing sticky adhesives from tape, labels, dirt from dust, fingerprints, drink spills etc. It is a cleaner for nearly anything you want removed, it is made from fish oils and is really inexpensive. What is it you might ask? I have cleaned many, many, many records with WD I have thousands , I've removed the little sticky "dots" that some DJ's use on the vinyl prior to my getting them, it works like a charm.
To remove most kinds of dirt from a non-porous surface, simply spray enough WD onto the offending matter to saturate it, then let it soak for 10 minutes or more. Wipe it off and the gunk will come with it.
For stubborn material like double-sided foam tape, several applications will be needed to get it all off. Don't forget, it will work best if you remove as much of the material you can before you soak it. Labels that have a shiny surface are tough, you need to peel off as much of the label as you can, otherwise the WD will not penetrate into the sticky part. If you are worried about the oily residue left behind, you can clean this with Windex or rubbing alcohol, otherwise it will tend to evaporate by itself.
I have found that simply wiping the vinyl record with a soft dry cloth will remove most of the WD, but I've never had any problems by leaving it dry by itself. WD is my first choice for cleaning almost anything. Hope this helps! Reply 4 years ago. Well Im an 80s child so I was stoked. But the record was bad with clumps of dirt.
I tried alcohol at first but then i tried the wd I sprayed some on a microfiber cloth and wiped gently in one motion around the record. Then I used a damp dishsoap microfiber cloth to clean the wd40 off. I think it still has some wd 40 residue certainly smells like it but it plays so smooth now!.
