Future echoes on vinyl

    Nah, not a Red Dwarf reissue.

    In quiet patches on certain albums I can hear the music from a second or two further on in the song. I've read about print-through on albums originally recorded on tape, but what about more recent ones that were not?

    Can this also be a function of a bad pressing? Stuggling to see how though, as wouldn't it mean the groove wall had somehow been breached, or part of the other side of the grove wall had somehow leaked across?

    Enlighten me please colleagues.

    It's one of all the great qualities of vinyl records. Pre-echo...

    Deebster,

    The vinyl LP is a time-travel device that lets you hear your music a few seconds before it starts. If you play your records backwards, you will know how they sounded a few seconds ago.

    I assume you were just about to play Pink Floyd Meddle.

    It’s tape Pre echo!

    The only reasonable explanation is tape pre-echo. Modern releases should not have it.

    Tape print-through. Not ‘pre-echo’.

    As per the Steve Hoffman: If it occurs an LP revolution before you hear it as the main audio then its probably down to the cut disc being deformed. e.g as one rotation is cut, the pressure shifts the previous adjacent cut rotation beside it.

    Hmmm, what would happen when playing the Future Sound of London back catalogue?

    Maybe produced by that well-known sonic effects man, Rick O'Shea ?

    Correct, I was imprecise.

    https://forums.stevehoffman.tv/threads/what-causes-the-pre-song-on-a-lp.328880/ seems to cover it nicely. Think I've learned something.

    Hadn't given the vinyl mastering side of it much thought til now, but it makes sense that the groove cut on one rotation can get deformed if the groove on the next rotation contains more musical information in it. Similar to what happens when making spirals in wet sand I suppose. Big one squeezes out little one.

    This is a separate issue to tape print-through though.

    I have one LP, Treason by Gryphon, which has a quiet drum track recorded on the lead in track then the band come crashing in. I suppose the idea being that you never know when the track starts. The effect is spoiled by the sound having a pre-echo of main intro 1 revolution before it comes in. I feel that the adjacent groove is a little deformed and comes through on the lead in groove.

    Bloody annoying in some tracks - OST Rocky has plenty- seems like the energy of French horns are big culprits for pre-echo...
