NAME

dir2ogg - Convert MP3, WAV, and M4A files to OGG format

SYNOPSIS

dir2ogg [ options ] ( filename [filename2] ... || directory [directory2] ... || [cdrom-device] ... )

DESCRIPTION

dir2ogg converts MP3, M4A, WMA and WAV files to the open-source OGG format. dir2ogg is a python script that simply binds together mpg123, faad, and oggenc making it easier for the user to convert his/her music files. OGGs are about 15 to 20 percent smaller than MP3 files, with the same relative audio quality. dir2ogg can be called with the -d flag at the command line to convert any number of directories at once, or given MP3, M4A, WMA, and/or WAV filenames as arguments, dir2ogg will convert only those files. If converting WAV, M4A or WMA files with -d you must add the -w, -m or -W command line flags respectively. These flags are not neccesary unless using -d. Note that converting M4A files requires you to have faad installed, and converting WMA files requires mplayer.

Keep in mind that converting from MP3 or M4A to OGG is a conversion between two lossy formats. This is fine if you just want to free up some disk space, but if you're a hard-core audiophile you may be disappointed. I really can't notice a difference in quality with 'naked' ears myself.

General Options

-h or --help

print quick usage details to the screen.

-d or --directory

convert all MP3 files in directory. WAV and M4A files will be converted if used with the -w and -m command line flags.

-r or --recursive

like -d but descends recursively into directories.

-c or --cdda

Convert an audio CD into ogg. You may pass the device as an argument to the script (default: /dev/cdrom). Requires cdparanoia orq icedax or mplayer

-p or --preserve-wav

preserve all WAV files. By default they are deleted.

-P or --no-pipe

Do not use pipes to send data from the decoder to the encoder, use temporary wav files instead.

--delete-input

Delete the input file after conversion

-v or --verbose

increase dir2ogg's verbosity.

Conversion options

--convert-all

convert all supported audio files to OGG. Only used with -d or -r. Requires at least mplayer.

-f or --convert-flac

convert FLAC files to OGG. Only used with -d or -r. Requires ogg123 or flac or mplayer.

-m or --convert-m4a

convert M4A files to OGG. Only used with -d or -r. Requires faad or mplayer or, for alac, alac-decoder (though mplayer will work, too)

-W or --convert-wma

convert WMA files to OGG. Only used with -d or -r. Requires mplayer.

-w or --convert-wav

convert WAV files to OGG. Only used with -d or -r.

-n or --no-mp3

ignore MP3 files when converting a directory. Only used with -d or -r.

--(cd|flac|m4a|mp3|wma)-decoder=COMMAND

Set the decoder you want to use for one filetype, e.g.: --mp3-decoder=lame. Run dir2ogg --help to see the available decoders.

-qN or --quality=N

OGG quality. N is a number between -1 and 10. Default is 3. Decimals are OK (ie: 3.7)

-t or --smart-mp3

Try to use the same quality as the input file. MP3 input only!
