Removing a specific value - but only for a specific fileformat

I have just scanned my collection and found "Whole lotta love", "Gotta be strarting something", "Loretta", "Violetta" as part of a Verdi opera, "Outtake" as part of a title, "Attack of the clones" - so there are a lot of titles (and probably filenames) with tta in them
I also wonder how the presence of these 3 letters would lead to

@Zerow

data loss

As @ohrenkino told you: This will also remove the bold marked text from titles:
Let tta and Cathode
or
Too young tta way

Either I am unable to imagine negative consequence - or both of you did not understand me


The data loss will occur precisely in such cases like @ohrenkino examples - if I will not use the first fail safe [i.e. " tta" with a pause]

All in all, based on this

But I need this as an single action; as in using a single groups action and not combining it with other Mp3tag features

If you really want to go that way, you could use something like this in your "Format value" action:
$if($eql('TTA',$upper(%_extension%)),$repl(%TITLE%,' tta ',' '),)

[...]

I went with

$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),)
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)

as I failed at adding The fourth optional parameter enables ignore case (1) [Scripting Functions – Mp3tag Documentation]; i.e. those did not work

$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' ',1),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' ',1),)

and neither did those

$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),1)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),1)

And on the side note- I stumbled upon a bug: Similar actions get mixed up when using abbreviated function name
