I'm seeing two problems with how Audition CS6 (version 5) saves metadata:
Problem 1:
After saving a file as a WAV file when you view that file in Windows Explorer many of the metadata tags have the last character truncated. The only way that I have found to solve the problem is to add a trailing space on each fields entry. In fact if you change the Recording Date to say "2012" the date won't show up at all in Windows Explorer, but if you save it as "2012 " it shows correctly.
Problem 2:
If I open a WAV file to save it back out as an MP3 - it doesn't matter if I do a batch process or one file it is the same - all the metadata is lost (YES, I have the "Include markers and other metadata" box checked). I follow these steps.. Open the Wav file>Click "Save as">set Format Settings to MP3>check the include markers>click OK. At this point if you look at the resulting mp3 file in windows explorer you will see that no metadata is present, but if you still have the file open in Audition it appears that all of the metadata is there - you can even try changing a value and saving again, but Windows explorer still shows no data. If you completely close the file in Audition and then reopen the mp3 file in audition, you will see that there is NO metadata there either. At this point you can then repopulate the data in audition and save the file and then it will show the metadata when viewed with Windows Explorer. VERY Annoying!!
Am I doing something wrong or is this a bug in Audition... It sure looks like a bug to me!!
