Is it possible to re-encode from FLAC to FLAC and discard all metadata blocks(except the mandatory STREAMINFO block), leaving just the audio frames? Or would I have to decode to WAVE first? I'm searching through the docs, perhaps I just overlooked something.

Thanks a bunch.

Reflacing using retains the metadata. However, if you it will lose the additional WAV metadata, still without an intermediate WAV file.

Gotcha, I think, so this will send the decoded FLAC file to the standard output, and pipe that back into flac. What does the first hyphen do after piping back into flac(between 'FLAC' and '-o' in your code)?

The "-" immediately after FLAC indicates that input to FLAC is to be taken from STDIN.

Ok, I understand. Thank you for the help.

Did you try "metaflac --remove-all" ???

Ah, that is surely another alternative. I personally would specify '--dont-use-padding' to remove the unused space. I wonder if one could use a '--remove-all' to remove everything, then further in the same command, add certain new metadata blocks, or if this would require two separate commands.
Thank You, I had forgotten about metaflac.
