Mass Tag/Filename Conversion


#1

I use mp3tag for my HUGE audiobook collection
at the moment I do the following steps 1 at a time:

  1. tag track #s
  2. rename file according to directory (track # - directory)
  3. get tag values from file name (title, author, album(series name) etc)
  4. change title to "title - track #"

I think i can do this all in one step using "actions" but i cannot figure out how to handle the fact that in mass processing, some books have album values (series name) while others are "stand alone" books

any ideas?


#2

I am afraid that without any concrete examples for each variation it is very hard to help as very often a single dot or blank in an action make all the difference.


#3

right
some books are named

(track#) - (Author/Artist) - (Novel/Title).mp3

Others are

(track#) - (Author/Artist) - (Series/Album) - (Novel/Title).mp3

I assume that all information is somewhere in the filename, right (why isn't it in the tags straight away? Filenames are only for dumb players that do not look at the tags).
Also I fear that you first name the files and then extract the information to fill the tags. I would recommend to do it the other way round.

Now, down to the other business.
I think that an action of the type "Guess value" would cater for most of your steps in one go:

Create a new action group for the standalone books
first action:
"Guess value"
select the field %_filename%
enter as mask
%track% - %Artist% - %Title%

second action:
Format tag field: Title
Value:
%title% $num(%track%,3)

do a similar thing for the books of a series.
First action like the first above but with a modified mask:

%track% - %Artist% - %album% - %Title%
or if you want to have series and title in the same field then the mask looks just like this:
%track% - %Artist% - %Title% - %Title%

second action like the second action for standalone books.

Is this, what you wanted?

Another general note: data structures that use implicit fields coded by their position always collapse if that position is not filled.
In your case a structure
Series Standalone
1: Number 1: Number
2: Artist 2: Artist
3: Series
4: Title 3: Title

falls one piece of the data short if position 3 is not filled.
So you either have to fill this position or treat the structure with a different procedure.


#5

Create a Action Group (FAQs: Actions ) with the following:

  1. tag track #s
    Action: Format Value
    Field: TRACK
    Formatstring: %_counter%
    (this can't reset the tracknumber for every folder. if this function is needed, you have to put this out for the actiongroup and use the Track Number Wizard, which can't be used as part of a action group)

  2. rename file according to directory (track # - directory)
    Action: Format Value
    Field: _FILENAME
    Formatstring: %track% - %_directory%

  3. get tag values from file name (title, author, album(series name) etc)
    Action: Guess Values
    Source Format: $if($eql($regexp($regexp(%_filename%,.?( - ).?,$1),(.* - ).,$1), - - ),$regexp(%_filename%,(.) - (.*),$1 - - $2),%_filename%)Guessing Pattern: %track% - %artist% - %album% - %title%

  4. change title to "title - track #"
    Action: Format Value
    Field: TITLE
    Formatstring: %title% - %track%

edit:
step 3 adjusted according the discussion below

Is the sequence of step 2 and 3 correct?
If so ... does it mean, that ...
"tag values from file name (title, author, album(series name) etc)"
... are part of the directory name?
That sounds rather confusing. You should check your procedure.

For working on files with different structure of the file name it is recommended to simply use the Mp3tag Filter.

This filter expression reduces the amount of files in the list view to those files which are constructed of 3 parts divided by 2 times ' - ', that means the filter expression detects the number of delimiter strings.

"$div($sub($len(%_filename%),$len($replace(%_filename%,' - ',))),$len(' - '))" IS 2

This filter expression reduces the amount of files in the list view to those files which are constructed of 4 parts divided by 3 times ' - ', that means the filter expression detects the number of delimiter strings.

"$div($sub($len(%_filename%),$len($replace(%_filename%,' - ',))),$len(' - '))" IS 3

If you like to put the importance on the parts, then you can modify the filter expression to detect the number of value parts, in this case 4 parts.

"$add(1,$div($sub($len(%_filename%),$len($replace(%_filename%,' - ',))),$len(' - ')))" IS 4

suche im Titel mehr als ein Paar "x - X" => "\ - |\d\d\d\d$

I have to do it that way because most of the time the mp3 do not come with tag values i want/find useful, and the file names are the same
so i rename the folder as "'Author' - 'Series' # - 'Title'" then do from there

so what you are saying is that i can create action group to apply filter to use only those with 2 parts in filename, do everything i want
then apply filter to use files with 3 parts, etc?


#8

Do you know that you can create user defined tag fields as you wish? ... and remove ... and use for all the things you want to do? You can use tag fields like temporary variables. You do not have to misuse folder names to store data. The filesystem does not support all characters and so there is loss of spelling accuracy to be expected.

Yes, divide and conquer, that's the strategy.
The filter is part of the interactive interface of Mp3tag, the actions are part of the batch automatiion interface of Mp3tag. Both together makes tagging life easy.

#9

my 4 step solution has the filter inbuilt to the formatstring by using a $if function and works fine. but do as you want


#10

i can figure out how to use the filters from the other guy in actions so i tried yours

it worked except for the TITLEs, it gets the track, artist, album, but does not get the title
from either the files with "track - artist - title.mp3"
or the ones that are "track - artist - album - title.mp3"
any ideas?


#11

ah yes, there was a little mistake caused by the forum's unability to display two following spaces.

that's the way:
3. get tag values from file name (title, author, album(series name) etc)
Action: Guess Values
Guessing Pattern: $if($eql($regexp($regexp(%_filename%,.?( - ).?,$1),(.* - ).,$1), - - ),$regexp(%_filename%,(.) - (.*),$1 - - $2),%_filename%)
Formatstring: %track% - %artist% - %album% - %title%

but already it should have worked for the ones which are written "track - artist - album - title.mp3"

nope, i dont know if i am doing something wrong but the TITLE is still not being grabbed from the filename

guess value,
Source Format: %track% - %artist% - %album% - %title%
Guessing Pattern:
$if($eql($regexp($regexp(%_filename%,.?( - ).?,$1),(.* - ).,$1), - - ),$regexp(%_filename%,(.) - (.*),$1 - - $2),%_filename%)


#13

I'm sorry. I'm using Mp3Tag in German and I've messed up the terms Source Format & Guessing Pattern.
It's:
Source Format:
$if($eql($regexp($regexp(%_filename%,.?( - ).?,$1),(.* - ).,$1), - - ),$regexp(%_filename%,(.) - (.*),$1 - - $2),%_filename%)Guessing Pattern: %track% - %artist% - %album% - %title%

thank works, thanks for your help
