Convert only WMA lossless -> Flac

[RSONNAD]

I have recently purchased a SONOS system. This supports WMA, except for WMA lossless.

So I now need to go through my library and convert only the lossless files (5000 out of 20000 total) to FLAC.

I see with db Batch Converter you can filter on extension, but I need to filter on specific codec.

Does anyone have suggestions for how to do this, or any other ideas on how to make a library SONOS friendly, without manually going though every file. I think one other option would be filtering on size. Most of the WMA Lossless are over 15k meg in size, so maybe I could trigger of that instead of the codec. But I still see now way to do that.

I'm not sure how well this would work, but you could try just doing a search in windows Explorer by size, highlighting the files shown, and right-click --> Convert To should work.

Could you use the extra columns that dMC (Reference) adds to Windows Explorer to search for the files?

Yes, it looks like you can sort wma files that way. The column name is "Audio Quality" and it reports my lossless wma files as "Perfect (Lossless)".
