[Flac] flac --replay-gain

[Ron Decline]

When I run it (OS X 10.6.2), find builds a list across multiple directories and then runs metaflac, causing metaflac to report. "The FLAC file could not be opened.  Most likely the file does not exist or is not readable."

I would think this is the expected result as " {} + " is the same as -execdir, except that ``{}'' is replaced with as many pathnames as possible for each invocation of utility."  and execdir caused metaflac tol be executed from the directory that holds the current file."

The find option '-print' reports ALL my flac files:
.........
./Traffic/Last Exit/Traffic - Last Exit - 06 Feeling Good.flac
./Traffic/Last Exit/Traffic - Last Exit - 07 Blind Man.flac
./Traffic/Welcome To The Canteen/Traffic - Welcome To The Canteen - 01 Medicated Goo.flac
./Traffic/Welcome To The Canteen/Traffic - Welcome To The Canteen - 02 Sad and Deep as You.flac
..............
Then when metaflac is run:
The FLAC file could not be opened.  Most likely the file does not exist
or is not readable.
Traffic - Last Exit - 07 Blind Man.flac: ERROR: reading metadata, status = "FLAC__METADATA_CHAIN_STATUS_ERROR_OPENING_FILE"

The FLAC file could not be opened.  Most likely the file does not exist
or is not readable.
Traffic - Welcome To The Canteen - 01 Medicated Goo.flac: ERROR: reading metadata, status = "FLAC__METADATA_CHAIN_STATUS_ERROR_OPENING_FILE"
..................

Anyway, you answered my original question, and "metaflac --add-replay-gain" is the way to go (not flac -f --replay-gain as I had thought).  I just ran this though a script that recurses through directories and runs metaflac for flac files in each directory (which is on an album basis in my file structure).  

Thanks.
