View Full Version : WMA Lossless fails with "After Encoding Verify Audio"

02-16-2008, 10:01 PM

I just bought DBpoweramp reference to rip my 1000 CD collection into my hard disk. I decided to use WMA lossless for no particular reason other that I have a Windows XP PC and a MP3 player that support WMA lossless.

I'm trying to rip "Peter Gabriel - So". The CD is on AccurateRip database, but mine must be a very old pressing because DBpoweramp reports in all the tracks "X AR (12) i Secure". I think it means the ripping is OK, but the reported CRC is not.

I have the flag 'After Encoding Verify Audio' on.

Anyway, only the last track '09 - This Is the Picture (Excellent Birds)' gives me:
Error ripping to Windows Media Audio 10, 'Track 9' to '09 - This Is the Picture (Excellent Birds).wma' Error audio file failed verification '09 - This Is the Picture (Excellent Birds).wma'.

I also tried ripping to WAV using DBpoweramp and EAC, then use DBpoweramp to convert to WMA Lossless, but I got the same error with both .WAV.

The strange thing is that if I use Apple Lossess as a codec, DBpoweramp rip and verify this track without error or problem.

Should I re-rip my CDs (so far) using another lossless CODEC (Apple, Wave, FLAC, etc).

I founds this thread, but got no conclusion of what to use from here:

I have seen a comment on this forum that there is a known bug with the window lossless format that it sometimes appears to lose a few bytes in the output file.

The WMA file will be missing a few samples from the end, that is all.

Thanks for the tip people.

Today I ripped 'Eminem - Curtain call - the hits' to Wave (uncompress .WAV). Based on DBpoweamp all tracks were AccurateRip so no problems here (is a brand new CD after all).

Then, I selected all tracks, right-click and using DBpoweramp converted to WMA Lossless. OF course with "After Encoding Verify Audio" enabled.

track 10, 15 and 17 failed to verify. I converted back track 17 to .WAV and compared to the oroginal .WAV using an HEX comparison viewer.

There is an HEX number in the 6th position (header I think): 0x94 in the original and 0x95 in the copy back from WMAL file.

Then, beginning in 0x013D8638 to 0x013C02C there is a huge chunk of data that is different. That's a lot of data!!! Is this what you call 'a sample'? Why is in the middle?????

So far I ripped only 10 CD from my collection, but I asking you guys if is wise to continuing using WMAL. Do you have a better suggestion? Different data in the middle of the .WAV make me paranoid!

If you are interest I uploaded a "17-Stan.ZIP" file that contain the three audio files, the original .WAV, the .WMA (lossless) and the converted back to .WAV. Is huge (166MB) so be patient please.

thanks for your patient. And DBpoweramp Ref is excellent! Better than EAC. It worth the money....
