|
+* As the author(s) of taglib state in their comments, parsing ID3s is actually pretty hard. There are so many broken taggers out there
|
|
|
+ that it is tough to compensate for all their errors.
|
|
|
+* The parsing of MP3 audio properties (mpeg.lisp) is far from complete, especially when dealing with odd case WRT Xing headers.
|
|
|
+* I've parsed just enough of the MP4 atoms/boxes to suit the needs of this tool. l-smash appears to parse all boxes. Maybe one day this lib will too.
|
|
|
+* I've run this tool across my 19,000+ audio collection and compared the results to some of the tools above, with little to no variations.
|

+ That said, I have a pretty uniform collection, mostly from ripping CDs, then iTunes purchases/matched, and the Amazon matched. YMMV
