Happy Record Store Day you assholes

Yes, but it has to do with longer grooves if you will. So on a 33.33 LP the songs on the outer grooves sound better as the cartridge is tracking over on longer distance. There's something called inner groove distortion where it's harder for the cart and tone arm to track the songs near the end of a side ( i.e., shorter orbit). When you take a LP and divide it into 2 x 45 RPM twelve inch discs you've got way more distance to work with overall.

The issue you're describing is only tangentially (pun intended) related to groove length. The issue is related to the tangential velocity at which the information was recorded.YellowSnow said:Yes, but it has to do with longer grooves if you will.

Recall from your basic high school physics:
s = r*theta = groove length at a given radial distance, r, from the center of the album.
Vtangential = sdot = r*thetadot = r*omega, where omega is the angular velocity.
As r decreases from the outer grooves to the inner grooves, Vtangential decreases. When the album is cut, the information recorded via sound vibration becomes closer spaced (shorter wavelength) when the cutting stylus is closest to the center. This can affect both recording and playback, as can differences between turntable tone arm alignment and cutting stylus alignment. -
I don't speak engineering, unfortunately. That said, my reissues cut to two 45 rpm discs do sound better.Southerndawg said:

Since the LP and the 45s are the same size, that makes sense. They probably have wider grooves too, which would allow for recording at higher sound levels and greater dynamic range.YellowSnow said:

I feel like this is linear and there is just more room occupied with shorter orbits of inner tracks. I have to think about this and reread the above which some of it sounds like improvised... I did have my needle weighted too heavy I discovered which caused wow and flutter.

Right I remember.. The outer tracks move faster so would result in inner tracks having more compression. I think.

Ok so @Southerndawg is tabbed for physics consultant of the music bored. Next up what is an OHM and how does that relate to speaker impedance.
