I have a rather large vinyl collection, some of which i have recorded to mp3 and added to my iTunes collection over the years.
I have noticed that some of them are not being matched, and i am wondering what the cause is. I have updated the track and album info, but it still doesnt match.
In my collection (notice it says uploaded, not matched) -
and in the store -
It located and downloaded the artwork, yet it still wont match.
I understand from reading this question that it uses gracenote for matching, which may read parts of the waveform. Surely the waveform of my vinyl recording is the same, regardless of gain level?
One thing i have noticed is that my recording is 16 seconds longer - maybe this could be the issue?
