Okay, so I've started amassing a collection of Audiobooks and Audio
Dramas in AudioCD format. Compared to Music CD, ripping these to flac
on average requires more post-processing due to things like multiple
discs, incomplete, inconsistant, or missing CDDB data, or
chapters/episodes being split across multiple tracks or discs.
I like having my Audiobooks and Audio Dramas organized as follows:
1 file per Chapter/Episode.
Each file named with chapter/episode number and title if
chapters/episodes are titled or Chapter XX.flac/Episode XX.flac if
they aren't titled.
All the Chapters/Episodes of the same book/program in a directory
named for the book/program.
All Books/Programs by the same Author or in the same franchise in a
directory named for the Author or Franchise.
And with the following file tags:
Artist=Author's Name/Franchise Name as appropriate
Album=Book Tile/Program title
Track= Chapter/Episode Number
Title = Chapter/Episode title if there is one Chapter XX/Episode XX otherwise.
I've been using sox to concatenate tracks belonging to the same
chapter/episode and metaflac for fixing file tags, but I would like to
use scripts to better automate this process after I've gotten files
either sorted into a directory per chapter/episode or into the final
preferred filenames.
For sox, I'd like to create a script that, when executed, will descend
into each subdirectory of the working directory, use sox to
concatenate the flac files found there and spit out the result in the
working directory with a filename that matches the subdirectory whose
contents were concatenated. This problem has a similar structure to
ones I've used a for file in *.ext loop, but I've never done such a
loop where the parameters were directories rather than files with a
given filename extension.
Here is the contents of my untested massSox.sh:
# /bin/bash
for dir in *; do
cd "$dir"
sox * ../"$dir".flac &
cd ../
done
With metaflac, I'd like to create a script that will:
remove all tags for every flac file in the working directory.
set Artist and Album to specified values(if these can be given as
command line parameters or take from Album=../ and Artist=../../ that
would be great).
For each flac file with a filename of the form XX Chapter Title.flac,
it sets track=XX and title=Chapter Title.
for every flace file with a name of the form Chapter XX.flac, it sets
track=XX and Title=Chapter XX with similar for filenames of the form
Episode XX.flac
currently, I've got two scripts for tagging, one to handle the XX
Chapter Title.flac case that requires using ls -1 > filelist.txt to
generate a list of chapter titles and then doing a lot of cutting and
pasting to populate a list of nearly identical commands. The other
tagging script handles the Chapter XX.flac case and only requires that
I add hardcoded Artist and Album values and that there's enough lines
to handle the number of input files. I haven't encountered the Episode
XX.flac case yet, but I can convert tagNoChapterTitles.sh to
tagNoEpisodeTitles.sh with a simple sed command. I would think there
should be a way to do string manipulation of filenames to create a
loop, but my scripting knowledge is not that advanced.
Here are my skeletal tag.sh followed by my tagNoChapterTitles.sh:
# /bin/bash
metaflac --remove-all-tags *.flac
metaflac --set-tag=ARTIST="" --set-tag=ALBUM="" *.flac
metaflac --set-tag=TRACK=01 --set-tag=TITLE="" ""

Any help that could be provided in improving my scripts would be
greatly appreciated, and I'm open to suggestions for alternatives to
metaflac and sox for doing these jobs.
