Examples:

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

2013-03-05 21:53:29 +01:00
|
|
|
|
${1##*/} -a 'Franz Liszt' file.mp3

|
|
|
|
|
2013-03-05 21:53:29 +01:00
|
|
|
|
Set 'artist' to be 'composer', and 'title' to be preceded by 'artist', do not reencode:
|
2013-03-03 11:19:50 +01:00
|
|
|
|
${1##*/} -s -a '\$COMPOSER' -t '\$ARTIST - \$TITLE' file.ogg
