Do fingerprints cut off the last note? #124

Looking at the fingerprint configuration

If I understand the definition of filter correctly, Filter(type, y, h, w) defined here

For all of these filters, y+h <= 11 but there's 12 chroma features meaning none of these filters touch the 12th feature? (the note A or Ab maybe?)

Yes, I've noticed this a long time ago, one column of the spectral image window is completely ignored.
