Here is what the error log generated for this file

Error: ID3v2 'COMM' frame has invalid size 339 at offset 336 in file D'Angelo/01-03-D_Angelo-The_Charade-SMR.wav (length 115700268)

As the message says, the COMM frame in the ID3v2.3 tag has an incorrect size value of 339. From looking at the contents of the file, this value should be 211.

It seems that XLD got confused by this and made a bigger mess when trying to fix it.

It looks like the COMM size value was encoded using the ID3v2.4 format encoding rules instead of the ID3v2.3 format encoding rules. (The ID3v2 tag in this file is an ID3v2.3 tag.) If the COMM size field in the file is decoded according to the ID3v2.4 rules, this produces the correct value of 211.

I hope this information is useful to Qobuz in fixing their file encoding bug.

Hi Simon

Thank you for the analysis. Based on my rudimentary understanding it appears that the value for the "comment" field in the tag contains an incorrect value which was not calculated following proper tagging rules. This leads me to question how many WAV files which Qobuz sells suffer from the same issue. I also wonder if there is a way for Minimserver to be able to "deal" which errors such as these. If only a small percentage of the millions of music files which Qobuz (and other sellers) provide have similar problems this creates a nightmare for the end user. Legitimately purchased WAV files will not be loaded by Minimserver and subsequently not be displayed by the control point. I guess I can now further appreciate the many comments which indicate a preference in the way FLACS files handle tagging when compared to WAV. In fact the same purchased file downloaded in FLAC did not present any problem.

I wonder if there is a program which will analyze and correct tagging errors so Minimserver does not hiccup. I use Metadatics to tag under Mac OS however I used to run MP3Tag when I used DbPoweramp on the Mac in a Virtual Machine under VMWareFusion. Since Spoon now has a working version of his program for Mac OS I no longer have the need to run VMWare and Windows - thank god.
