Default "Ghost" notes on LP playback?

Has anyone else ever come across this?

Particularly noticeable on headphones. Put a record on the TT, cue up stylus, it sets down then just before the music starts you hear the preceding opening few notes very very quietly BEFORE the main groove info is produced properly (ie full volume).

It happens on loads of LP's I've got, most noticeable on loud rock that starts with a bang or a big riff, I hear a faint few notes then the proper full volume sound crashes in. I wouldn't say I actually listen to music very loud BTW.

Doesn't happen on CD.

Any ideas or is possible that I'm actually hearing to the future

no I have heard it too, on regular speakers, no idea at all, apart from the mix engineer, rather like a sort of reverse fade out.

Thats it Ian, maybe theres 2 of us listening into the future then!

I thought it might have had something to do with me 'experimenting' in my formative years....

Hi-i have noticed this for many years !

I always thought it was something to do with that part of the groove -before the music starts -picking up something through the groove wall.

Is there any proper technical explanation ?

Me too, I often wondered if it was "print through" on the master tapes where one layer can leave a very faint imprint on the one next to it? But then what do I know about such things!

Could be.

Other than that my old LP's have all 'gone off' and the notes are leaking a bit?!

Thats my tecknikal take anyway.

This is can be quite common on highly modulated discs and also on those where the maximum recording time has been "sqeezed" onto the surface. One grove "effects" the adjacent "groove" which results in a similar result to print-through on tape. It may, of course also be the result of print-through on the master tape...

Oh, <sulks and crosses arms> It all sounds quite feasible now.
