blank spectogram for FLAC, only appears in mp3

[EliaRouge]

as title when checking downloads in spek.app the app shows a blank (all black) spectogram for FLAC 16 and 24 files while it shows the correct spectogram for MP3. same song, same setup, DAB keys correct.

I just pushed out a new updated. I fixed several issues with the downloads. Give it another go with the newest version and it should be much better now.
