Mp3 Tag File

Buttons/Scripts
, ,
1

This script, inspired by @Steve link, allows us to edit the metadata of a single Mp3 file at a time, although, through the navigation buttons, we can reach other files and edit them as well.

Important: When modifying a file, before moving to another, we must save the changes.

01

To install it, just download it:
Mp3 Tag File.js.txt (18.8 KB)

And copy it to:
"/dopusdata\Script AddIns"

Once installed, we only have to create a button with the Mp3TagFile command.

The musical genres present in the "Genre" drop-down list are those of Opus, located in /dopusdata\ConfigFiles\musicgenres.xml

However, this list can be edited to individual taste, adding or eliminating genres. To do this, just go to Preferences > Toolbars > Scripts and click on the Scripts Management link, or directly access this window through a button with the command Prefs PAGE=scripts. Once in this window, just locate the script (Mp3 Tag File) and click on the gear shaped icon.

04

Before finishing, I want to once again express my eternal gratitude to @errante, @lxp, @WKen and @bytespiller, four giants of programming, for all the help provided, without whom the creation of this script would not have been possible!!!

Any chance of an English version of this?

4

Oi @juic3 , yes, I can do it, but I don't know whether to add a string with the English language to the original script (the same musical genres would be maintained), or make a completely new version in English, with the most common musical genres for you .

Could you tell me the most common genres for you, the ones you would like to exist in the "Genre" drop-down list? I could do it by searching on Goggle, but it will never be the same as someone's proposal.

5

Send me a message with everything you would like translated to English and I will do so... I would love an English version of this script, its what I've wanted for forever

6

Hello @travibe , thank you very much for your willingness to help me, but I have no problem doing the translation into English, they are few words and very easy to translate, what I would like you to help me with would be in the musical genres that you, the speakers English, they use more frequently, which with certainty, must be very different from those that I specified in my list of musical genres (Latin and Brazilian)

Help me with that, send me a list of the most common musical genres there, thank you very much!

How about this list?

I got this from my Tag&Rename program... I couldn't specifically pick out the most popular because that would be different for everyone.

Thank you very much for your list, but I just published the version of the script in English with the list suggested by @lxp, Opus' own, try the script and tell me if it is okay, thank you very much!

11

Did you see it? Our prayers have already been answered:

Added scripting DOpus.MusicGenres() method to access the list of defined music genres

You can now maintain all your genres within Opus and use them outside the metadata panel.

To feed them to your dialog, use

for (var e = new Enumerator(DOpus.MusicGenres()); !e.atEnd(); e.moveNext()) {
    dlg.Control("genero").AddItem(e.item());
}

It makes me very happy to see that Opus is becoming more perfect every day, that things are becoming more simplified every day.

I will try to implement this method in the script, thank you very much!

@travibe and @khalidhosain I have updated the script, thanks to the help of @Wken, now is possible to edit the list of musical genres, just read the description of the script, enjoy it.

Absolutely fantastic script it's becoming one of my go-to favorites! Is the best for on the spot quick fixing any files that have random erroneous entries or whatnot instead of having to load a whole program and have it scan the folder and all that nonsense. I would place this in the top five best scripts of all time (seriously!}!

Just like the post one or two above this one stated, watching DOpus grow and evolve into the best file manager while also playing a very tiny part in it ourselves (i.e. the community) is a very very cool thing indeed. It's little fixes like this that the community contributes which adds to DO's already massive list of capabilities that set it so far ahead of all the other competitors. Go team! Lol

I am very happy that you liked this script, I did it with a lot of love, thinking of something simple and quick to use, I assigned the F4 key to the button and I don't even need to press the button.

Now I'm thinking about inserting two small buttons to jump to the previous file and the next in case it is necessary to edit other files. I'll let you know when it's ready in case you're interested in this new version.

17

I forgot to tell you about Opus, for me it is the best file explorer in the world, for three simple reasons.

  1. Versatility (high number of options and functionalities).
  2. Very high level of customization (practically everything can be customized).
  3. Powerful technical assistance (that interaction with the forum community, which is practically instantaneous, is difficult to see on other sites).

Thank you so much for this nice Script. I have face a small problem.
When I Select multiple files with multiple track no. and multiple Title. then update only one field Album Name. when I click on save button, it's change all files track no. in same number and all my Title name is same name. but when I select multiple files and I didn't change or input any value in the track no. or Title: field then I want my track no and Title should remain as it was.

2nd Issue. I need 2 more fields here for update or input copyright and publisher columns information.

@khalidhosain The script is designed to work with a single file, that's how I specified it in the description "This script allows you to edit the metadata of a single Mp3 file". If you select multiple files, the changes you make will be applied to all files.

To edit several files at the same time, respecting the different values of each file, I recommend using Steve's script (link), which I also refer to in the script description.

Regarding the "copyright" field (item.metadata.audio.copyright), I did not include it because the intention of the script is really a quick and simple way to edit the most important metadata, I did not want a huge window with a lot of visual content.

In terms of music, I think the "Composers" and "Album artist" (Music producer) fields are most used, however, these days, when I can, I will make a version for you with those fields added.

The built-in metadata editor also handles multiple files.
