hmm
that could be so.
but at the lower speed, it could be that the frequency ceiling could be lower. i dont know.
i was just making an observation. I've never seen those spikes on mp3s |

If you work with vinyl you also have to work with the needle, wich has a certain bandwith aswell, maby it's 'improved' for dance music and has an earlyer roll-off on the high freq to reserve the extra energy for the low-end...
but I'm probably just talking sh*t, but it seems logical though, the better the needle the better the sound... |

From what I've read, vinyls are cut pretty sharply after 16khz in the mastering because, like Qbical suggested, the needle has a certain physical limit to what frequencies it can reproduce. On the other hand, I just looked through some specs for a bunch of styluses and they all supported a range typically from 20-20000 Hz, so that shouldn't be a problem  Looks like I/we need to do more research on this matter.
As for the spectrum that is an mp3, you might be right there. The file I used to produce that curve was an wav file, but it is possible that the source I got it from at some point might have had it as an mp3 and then converted it to wav without thinking about the results? Anyway, it seems I'll have to do an extensive analysis of various vinyl tracks to clear this up. I'm going to transfer all my vinyls to a digital medium at some point in the near future, probably over the summer. At the same time I could do some research into this matter.
Anyway, thank's for pointing out the possible other reason for the cut at 16Khz, Atlantis  |
