Are 45rpm vinyl records better than 33rpm records? Vinyl theory with dr. dub.

[@michaelbradley7595]

45 rpm 12"disco singles in the late seventies and early eighties had the best sound quality that vinyl could produce.

Facts

[@bcarlyle7741]

A lot of the development of hi-fi stylus shapes has to do with extracting high frequencies from inner grooves. At 33 rpm, a conical stylus drops off around 12-14 KHz by the end of a side, and an elliptical extends this to around 18 KHz. The Microline and Shibata stylus are capable of retrieving ultrasonic information across the entire side with the latter being developed specifically for CD4 quadraphonic compatibility requiring response beyond 40 KHz.

I agree indeed and depends on equipment too and how good a pressing is. Lots of iffy facts.

[@stevejohnson1321]

Depends on "the 45," because a 12-inch "big single" allows higher amplitude between grooves. Mastered properly, that lends to improved dynamic range. That's one problem the CD helped solve.

[@charlottewhyte9804]

well yes indeed

[@sambuka57]

Very concise

just got a t560 from master souri! Glad we found your page!

Great info Dr. Dub ! Hello to Benni :)

[@Pisti846]

I would think a 78 microgroove would be even better.

[@ChrisMezzolesta]

You should hear the 78s being put out by Rivermont Records - stereo microgroove at 78 sounds phenomenal...

Nice video!

[@charlottewhyte9804]

I had bad 45 discs too so singles for example,many had poor quality.

[@chichanleon123]

I have lots of 45s and almost all of them sound better than my 33 rpms

[@GordonPyzik]

Strange that no one ever says that the extra speed of a 45 hurts the sound. Its logic

[@vinylrecording]

What do you mean by "hurts the sound"? Only thing I could think of is the noise floor which is a tiny bit higher

[@SPAZZOID100]

45 ALWAYS!!!

[@val058]

but much mastering of 45's in the 60's 70's sounding harsh vs their LP counterparts. Not sure why -- but the LP would be quiet and smooth by comparison.

[@blackhawkjohn1]

How much music does the normal 45rpm record hold? Is there a maximum time limit? Say 4 minutes or 5 minutes? Does anyone know? I can’t find it anywhere on here.

HE SAID IN THE VIDEO!

@@pnichols6500 my bad, I must have missed it while doing something else at that particular moment.

[@pnichols6500]

@@blackhawkjohn1 Well, my all caps was probably a little dramatic. But I have a fair amount of these 45 rpm 1/2 speed masters, and it can vary a lot, some sides are just one long song, but usually you see about 3 per side and about 10 to 14 minutes long it seems. I find the sound has more bottom end mostly, but also a better soundstage.

[@hadleymanmusic]

More imformation on 45

[@hilarylawrence4588]

Same thing, just smaller and fewer songs! Also the speed is faster.
