Recently I found that I had two copies of a several tracks in my collection, one copy that I'd transferred from vinyl and another copy I'd acquired as mp3's (typically of dubious origins though probably sourced from CD). Making a few listening tests I noticed immediately that my vinyl transfers all sounded a little slow. Making some waveform measurements I estimated the speed error to be about 2% to 2.5% (too low) for my vinyl transfers.

The first thing I was wondering is if most people would consider this a serious problem or not? I was thinking about correcting the speed using software. I think audacity for example can speed up or slow down the audio so if I've got lossless copies it would seem fesible to correct it this way. Does this seem an ok way to do it?

The other question is : does this mean my turntable is crap? I just measured the speed, with only the platter spinning and no record or needle drag, and it was only going at about 32.7 RPM. There is no speed adjustment, at least no external one that I can see. It's a JVC belt drive turntable (I don't have it here with me at the moment so cant give more details). Just wondering if there's ususally any way that you can open them up and adjust the speed?

Does anyone else here tweak the speed of their vinyl rips in a wave editor. If so what procedure do you use?

Thanks. smile.gif
