Maybe misunderstanding, the cdxl parser provides score of 1, the DAT 
patches provide a score of the count of detected frames so better.
But attached is a v2 of the 2nd patch, less compilation warnings, using 
less metadata not impacting the decoding and handling corner cases like 
bad metadata e.g. 16-bit 4-ch (impossible) and 32 kHz 12-bit 4-ch.
12-bit is not yet handled but the patch provides the detection of such 
file and a smooth rejection of the file.
