--------------------------------------------
extract audio and data tracks from CD images
--------------------------------------------
:Manual section: 1

:Version: |version|
SYNOPSIS
========
miragextract [**-l**] [**-s**] [**-t** track] [**-b** base] [**-f** fmt] [**-p** passwd] [**-q** quality ] **image-file**
DESCRIPTION
===========
Extracts data and audio tracks from any CD image supported by libmirage.
Data tracks are written as-is, and audio tracks can be written as-is or
converted to wav, flac, or ogg/vorbis (via libsndfile).
OPTIONS
=======
--help
Print short usage string.
-a Extract only audio tracks. Default is to extract all tracks.
-b <name> Sets the base filename for the output files. Default is **track**.
Can be prefixed with a directory to write files in that dir,
but the dir must already exist (example: -b extracted/track). See
also the -n option.
-d Extract only data tracks. Default is to extract all tracks.
-f Sets the format and filename extension for the output audio files.
Choices are **wav**, **ogg**, **flac**, **cdda** (raw CD audio).
Default is **wav**.
-l Lists the tracks in the image without extracting them.
-n Set the base filename to the input filename, minus its extension.
E.g. for foo.cue, this is the same as saying "-b foo". Beware of
using input filenames with directory separators in them: the output files
will be written in the same dir as the input file. Hopefully you
have permission to write there.
-p <passwd> Password for encrypted images. Note that anyone who can run **ps(1)**
on your system may be able to view the password. Also note that password
support in miragextract is *completely* untested: I have no
encrypted images to test with.
-q <qual> Quality setting for ogg and flac output files. Integer from 0
to 10. Default is 7. Has very little effect on flac, and no effect on
wav or cdda output.
-s Swaps bytes in audio tracks. Use this if your audio files sound
like white noise or gibberish.
-t <track> Takes a track number (1-99), and extracts only that one track.
Default behaviour is to extract all tracks.
Always include a space between an option and its argument (e.g. **-b foo**, not **-bfoo**).
NOTES
=====
Image-file is e.g. a .cue, .ccd, .nrg, .mds, or anything else supported
by libmirage. See the README for your version of libmirage for details.
Output files will be overwritten if they already exist, with no prompting.
Output audio files are named track01.wav, track02.wav, etc by default. The
'track' part of the name can be set with -b, and the extension will
match the encoding set with -f. Note that mp3 is NOT a valid -f option.
If you need mp3, extract to .wav and then use a tool like lame or ffmpeg
to convert to mp3.
Output data tracks will be named to end in '.iso' by default, or '.hfs'
if they look like Apple disk images (HFS or HFS+), or '.hfs.iso' for
"hybrid" images that can be mounted as either ISO9660 or HFS/HFS+
(such as Blizzard's Mac/PC releases).
Images with multiple sessions should be supported, but have not been
tested. Track numbering just continues, so a disc with 2 sessions of
8 files each will have tracks numbered 1 to 16 as far as the -t option
and the output filenames are concerned.
When extracting raw CD audio tracks, you can test them by listening to
them with the *play* command from *sox*. Try::
play -x -t cdda track01.cdda
...possibly without the -x option if you're on a big-endian platform.
.. other sections we might want, uncomment as needed.
.. FILES
.. =====
.. ENVIRONMENT
.. ===========
EXIT STATUS
===========
As usual, 0 for success, non-zero for failure.
BUGS
====
The -p option should prompt for a password.
Not exactly a bug, per se, but miragextract can't deal with multi-file
images where one of the files is missing or truncated. This is because
libmirage validates the image when it's loaded, and is unlikely to change.
Related to the above, there's no attempt to recover from
errors. miragextract exits as soon as it encounters an error of any kind.
