WMA Lossless is obviously supposed to fully preserve the source data, however
it appears that sometimes the last few samples of a file will be thrown away.

(Note: For those interested in recreating the problem I have uploaded a "problematic" wav file here: http://rapidshare.com/files/REMOVED* )

If I convert the above file to WMAL using dBpoweramp and Windows Media Audio 9.2 Lossless codec I get (when After Encoding Verify Audio option is checked):

Error converting to Windows Media Audio 10, '06 - Melibea - Boheme.wav' to '06 - Melibea - Boheme.wma'
Error audio file failed verification '06 - Melibea - Boheme.wma'.

If I convert the above file to WMAL using Windows Media Encoder, I get no messages but then if I bit-compare the results using foobar2000 I get:

Comparing:
"06 - Melibea - Boheme.wav"
"06 - Melibea - Boheme.wma"
Comparing failed (length mismatch : 5:35.440000 vs 5:35.439819, 14792904 vs 14792896 samples).

Can anyone help?

Moderation: Removed sample. I haven't downloaded it but from the size of it it is longer than the 30 sec we allow here.
