One of the more advanced features of mp3ql is the Tag Editor.
Its primary function is to aid the naming of id3 tags, be
it single or multiple files. In order to grasp a full understanding
and benefit from it's capabilities it is well worth studying
this page ... once the basic ideas have been absorbed there
are few limits on what can be achieved, and the often long
and tiring process of naming multiple files will be drastically
shortened.
In order to edit tags you must initially select one or
multiple files using the view of your choice, which can
be one of detail view,
icon view or playlist view. The tag editor will load the values
of the selected files into the available fields:
- Artist
- Album
- Title
- Track
- Total
- Comment
- Genre
- Year
- Image
In order to change a particular value just type into the
corresponding text field. The check box above the text field
will be activated automatically to indicate that you changed
it's value. Not every field has to be used, they can simply
be left unchanged as desired.
 To embed an album image
into a tag, first select the image box button. A square
area will appear to the left of the tag value fields. Simply
drag or paste an image into the box. If the desired image
isn't already copied into your clipboard or you choose to
set the image by drag and drop, you have to click the lock
button first:
 If the lock is activated,
the tag editor's file selection won't change when you browse
in the file views. After unlocking, the initial selection
will be restored in the file views.
 Once done, simply click
on the green tick and your changes will be applied to all
selected files.
 To abandon all your changes
and collapse the tag editor press the close button.
Notes
Any image format supported by your Qt installation may be
used for the image tag. Those normally include PNG, BMP,
XBM, XPM and PNM. It may also support JPEG, MNG and GIF
To switch to advanced mode click on the mp3ql icon ( ), now you will see a secondary field
next to all the primary fields (including a Path and File
field) which can be activated and deactivated using the
smaller mp3ql icons. The secondary fields are used to specify
the format of the primary fields using the following escape
sequences:
- %i = Artist
- %a = Album
- %t = Title
- %n = Track Number
- %c = Comment
Here is an example, let's say your files are named in this
format - john doe - the unidentified
man - 01 - they don't know who i am.mp3 - we break
this down into smaller parts that mp3ql can understand:
- john doe = Artist
- the unidentified man = Album
- 01 = Track Number
- they don't know who i am = Title
Now we know what the title consists of we need to find out
the corresponding escape sequence, in this case: %i
- %a - %n - %t, remember to specify the hyphens.
So now we have our escape sequence we need to give this to
mp3ql, because we are taking this information from the File name we click on the File mp3ql icon and
type the escape sequence into there, this tells mp3ql where
to extract the information from, then press TAB, and you will
notice the relevant fields now have the corresponding character
inside them...this way you can check that everything is correct
by referring to the list above. If you would like to save
the escape sequence for later use press ENTER and you will
now see that it is in the drop down list. Now that we have
specified the information required all that remains is to
press the green tick icon (), and you should now see
that these details have been written to the tag.
The above process can be used for any of the fields (except
for Total, Genre and Year). The rule of the process is that
you must first specify to mp3ql the format of the details
in order to extract them. As you can hopefully now see, there
are many ways this process can be used to speed up the naming
of tags.
Currently, mp3ql is not able to read or modify ID3 tags
of version 2.2. If you encounter such files you have to
delete the tags or upgrade them to V2.3 or V2.4 with an
external tool. The same might happen ocasionally for files
with invalid ID3 Tag frames.
