Background Noise

[Guest]

is it common for there to be much "background noise" on 7" records from new?

Hello Mick,

The answer to that question is, it depends on the vinyl quality used.

There were a lot of small pressing plants that used poor quality vinyl, these records will have light background noise from new. There is nothing that can be done about this. Some very rare records, for obvious reasons, were pressed on this type of vinyl.

A major company, for example RCA, used the best quality vinyl. These will have no background noise.

Styrene was a budget material used, example Shrine label, that produced a very clear sound reproduction when new. However, just one play on a faulty stylus will tear the groove, thus producing hiss. Also too many plays will eventually cause wear & produce a distorted sound.

If you have a particular 45 that comes to mind just pm me & I may be able to tell you if it was a record that was produced with noisy vinyl.

Regards,

I posted a list of terms and definitions years ago that someone posted on KTF years ago....here's the biut about nvinyl and it does explain abit about noise.....

Vinyl (properly Polyvinyl Chloride).

Relatively flexible material used since the early 1930s to make

non-breakable records. Its fumes are an acknowledged carcinogen, so don't

breathe in deeply when you have your next holy burning of Beatles or

back-masked devil-worship records. :-) Usually pressed by Compression

Moulding which allows the label to be an integral part of the pressing

itself. This process also requires that there be extra material which spills

out the sides of the press, therefore this extra material is routinely

ground up and re-used. Because vinyl does not re-heat and re-cool to a

smooth, glossy surface, the excessive use of re-grind mixed in with Virgin

Vinyl can account for the inherently noisy surface of even Unplayed Mint

examples of the cheap pressings that some record companies used. Noise can

be seen AND HEARD by looking at and/or playing the un-grooved surface of the

lead-in and lead-out areas. If this area looks or sounds grainy, then the

grooves will also have some of this grainy background sound. The stampers

used for the compression moulding process will start to break down after

only 1,000 pressings because they are forced to expand and contract when

heated by steam at the start of the pressing cycle and then cooled to

solidify the record. Some companies routinely overused their stampers for

their pop record series.

I've just tidied up an mp3 which was from Originally sourced from Vinyl with Scratches, Pops & Clicks, etc & IT WORKED

Got me thinking, are there any REAL TIME filters Available for Vinyl. Record Deck to AMP, that remove Scratches, Pops & Clicks, Hiss etc

Try recording in Mono this cleans up 90 0/0 of noise I wire my leads left + right positive.

Yep, there is. The name currently escapes me, but on the odd occasion when I had to master from vinyl for the Mastercuts series I used a real time filter called.......I think it begins with an 'F' or 'S'...........?

It's quite well-known and I'll probaly remember it tomorrow LOL........

I thought Cedar was industry standard Ian? Not sure if it's a real time application though.
