Some Frequency Spectrum Results Not Showing

[NativeSun]

Sometimes I download music from an online source and get multiple files of the same song.

I then use Fakin' The Funk to help decide which of the files that I have  downloaded is the highest quality to decide which ones to keep.

This works sometimes, but most of the time it will show me one of the frequency spectrum results for both songs.

What does this mean?

For instance I will look at the frequency spectrum results for "Pink Floyd - Sheep" and "Pink Floyd - Sheep (2)"

But it will show me the same frequency spectrum results for both files.

What does this mean, and how do I decide which file is the highest quality audio file?

"Fakin' The Funk" first calculates the MD5-Hash of the filecontent to check if there is already a calculated spectrum for it.
If so, it re-uses the already existing one. This will show the "wrong" filename, since it was computed from a different - but identical(!) - file.

The hash will uniquely identify the file by its content (filename does not matter!) and is much faster than recomputing the spectrum. That's the reason why it is done this way!

So it looks like you have simply downloaded the identical file from different sources!

If you want to enforce a recalculation, hit F5 when the spectrum is shown (or use the right-mouse-key)
