Options:

-p : preview (do not change file)

Tags:

-a : artist

-g : genre
|

-l : album

You can use the following variables to refer to existing tags:

\$ALBUM

\$ALBUM_ARTIST
|

\$ARTIST
|

\$COMPOSER
|

\$DATE
|

\$TYER
|

\$GENRE
|

\$TRACK
|

Default output folder:

OUTPUT="\$TC_AUDIO_DEST/\$OUTPUT_ARTIST/\${OUTPUT_ALBUM:+\${OUTPUT_DATE:+\$OUTPUT_DATE - }\$OUTPUT_ALBUM/}"
|

Default output file:
|

OUTPUT_FILE="\$OUTPUT\$OUTPUT_ARTIST - \${OUTPUT_TRACK:+\$OUTPUT_TRACK - }\$OUTPUT_TITLE.\$OUTPUT_FORMAT"
|

Examples:
|

|
||||
Set the 'artist' tag and reencode:
|

$1 -a 'Franz Lizst' file.mp3
|

|
||||
Set 'artist' to be 'composer', and 'title' to be preceeded by 'artist', do not reencode:

$1 -s -a '\$COMPOSER' -t '\$ARTIST - \$TITLE' file.ogg

|

Set the 'artist' tag and reencode:

Set 'artist' to be 'composer', and 'title' to be preceeded by 'artist', do not reencode:
