What dbPowerAmp does is encapsulate the wav file into a FLAC container without actually compressing it. I guess it can be a bit arguable if you can technically call it a FLAC file :) It's like using "Store" mode in RAR, for instance. The idea behing this "uncompressed FLAC" is to give the FLAC tagging abilities to people who don't want to compress their files. But as WAV is lacking in the tags department (some workarounds, but most players are not compatible with those), dbPowerAmp uses the FLAC structure and inputs the uncompressed data inside. As far as I understood from the webpage, that's it. I don't think that option is available with the command-line flac. I think dbPowerAmp (and this is me purely speculating, mind you) manually builds the file by adding a FLAC header where the tags can be stored and then inserts the uncompressed wav in the data field of the file or something equivalent.

The FLAC standard allows for frames to be stored "as-is", specifically with the "SUBFRAME_VERBATIM" type - http://flac.sourceforge.net/format.html#subframe_verbatim Spoon's implementation is likely using this feature to store uncompressed data within a valid FLAC file that can be understood by any compliant FLAC decoder. -Ben Allison> What dbPowerAmp does is encapsulate the wav file into a FLAC container > without actually compressing it.

Mike, I went looking for that article and stumbled upon this gem. http://www.audiocircle.com/index.php?topic=103168 Enjoy.
