Question to all vinyl heads.
English

Does anyone know why a 7" single sounds different to a 12" single or LP? Noticed, have done for years, but never really felt the need to ask.

I've got quite a few 7" singles that I've kept either on 12" single or purchased the LP. The 12-inchers seem to sound more cohesive, generally.

Presume it's because all the music is on the inside of the disc so tightly packed.

RE: Question to all vinyl heads.

I think it has to do with 'groove spread'. The amount of space you have got to cut the amount of music into the disc.

In digital terms think of it as the amount you have to compress a song by to get it to fit into a given file size. Smile

RE: Question to all vinyl heads.

You know how the last track on any LP side usually sounds the worst? 

Look at the area of the LP it occupies compared to the area of the first track.

It's a lot less, even when the tracks are of the same duration.

Measure how much length of groove passes under the stylus, in one rotation of an outer track, compared to the length of groove passing under the stylus in one rotation of an inner track.   It's massively longer (but occupies the same amount of time). 

Same with a 7" single compared to a 12" single. The musical information can occupy a much larger area (and a much longer groove) on the 12" version.

Yes, regardless of what your parents tried to tell you ... size matters

RE: Question to all vinyl heads.

It's the same reason why singles probably should have stayed at 10" and 78rpm, even after the move to vinyl. But convenience won over SQ. Wow that doesn't happen very often does it [/irony]

78 is probably OTT.

RE: Question to all vinyl heads.

Back in the day, I decided to buy 12 inch only as yes they were better quality.

They also had picture covers simillar to LPs, I assumed the SQ was due to 12 inch being thicker vinyl and the 7 inch were basically cheap & chearful pressings.

I get your points above abiut compression etc and think I agree.

Have to admi I had a cut out picture disc of Macca and Rupert bear to my shame.

Literally.

I also read somewhere that they often used a higher percentage of recycled vinyl in the mixture for singles than for any other size. The number of times vinyl is recycable is not infinite as it breaks down so just that could be a reason for lesser sound quality as well as less longevity with regards to wear.

Couldn't agree more, DM. This what happens when the eco warriors work in the music industry. Smile

Or when the OAPEC nations quadrupled the price of oil in response to the USA supplying arms to Israel during the 'Yom Kippur war'.

How did that affect the price of oil?
