Get titles from mp3 filenames
I'm doing a ID3 mass editor, which works like this:
the user has an album (eg The Band's Finest), and wants to put an ID3 tag on all the files. This can take time, so i've made a mass editor for this. The program gets all filenames in the album directory, and stores them in a string array. the user types in all info, except the song title in the main screen. the user has the option to use "intelligent title generation", so that the titles for the id3 tags are generated automatically (since they are different for each song), but i'm not intelligent enough to get this to work.
Here's what i want it to do:
i want to 'extract' the title from the filenames. this can be done by checking the difference between two or more of the filenames, and seeing what characters are before and after the differences found, and then copy the difference (=the title) to a TitleArray, but how do i do this ?
another, IMPORTANT, thing: there are different formats for naming the mp3's. Most people use the "TrackNo Artist - Songname.mp3" format, but it may very well be different, and some elements might not even be there - some might be there many times!. Only sure thing is the extension. Also remember that some bands, or even songs begin with numbers, so isnumeric() won't do any good.
This has troubled me for a long time. please help. (if the question is not understood because of me being bad at explaining, i'll be happy to refine it)

You seem quite a hotshot, with fancy code and all. You're even the top VB answering-machine around here..
Naw, I didnt mean to be rude :-)
I was very pleased with all that code, but..
The code you posted is actually not what i had in mind. Writing the tags to the mp3s is no problem. In fact, this has really nothing to do with the mp3s themselves:
I have a directory which contains an album in mp3 format. There are certain patterns in those mp3s' filenames that are the same, eg the artist, the ".mp3" extension, possibly the tracknumber (+1 for every song). Now, how do I seperate the title from the rest? that is what this is all about.

i've made an InputBox where the users tells me what comes first, secon and last:
%1 %2 - %3.mp3
for
TrackNo Artist - Songname.mp3
but I still dont know how to handle this (without a million lines of code)

%1 %2 - %3.mp3

So, If I anderstand, it is only string manipulation, use the INSTR function
Give me a sample, and I will give you the code to extract what yo need

here's a sample (at least i hope it's a sample):
I have a directory, with the "Gamba"'s newest album "Plunder". here's the filelist:
01 Gamba - Hopalong.mp3
02 Gamba - Jorge.mp3
03 Gamba - Plunder for the people.mp3
04 Gamba - Are you Gamba'd.mp3
05 Gamba - I'm a horse.mp3
none of these mp3s have an id3 tag, so i've made a program that creates these tags from the filenames, and this program is supposed to be usable on all albums. I've set all the elements in the tag, except the songtitle, which is different for each file. Now, i want the code to single out the songtitle from the FILEname. I find this very hard, and to easify it, i've made an inputbox where the user tells me what order the TrackNo, Artist, and Songname are in, and one or more of those three might even not be there.
In my code, i've created a sorted Filename array which contains all the filenames (not path) for the album, and i've resized every element in the array with -4 to remove the ".mp3" extension.
How can i fill my Title array just by using the filename array and the inputbox' format of the filenames ?
Here is as far as i've come with the Title array:
For j = 0 To NumberOfFiles
ReDim Preserve Title(j)
Title(j) = Mid(FileArray(j), 1, _
Len(FileArray(j)) - 4)
Next j
...which only removes the ".mp3"
need more code? i dont think you need it, and it's extremely bad.

Use the following code :
sMP3 = GetTokens(sFile, " ")
it will return all the parts, but the last one will have the MP3 to remove

there is a module or class or something that also has a player with it ... i just don't know if it writes to the file but i know it can get the tag from the mp3
ASKER
sorry waty, but what if the format of the mp3 filename is like this:
TrackNo.Artist_Songname.mp
for now, i'm using a temporary solution: i tell the user to write the songtitle of a certain filename, and that way, i can find out the strings that are before and after the title, and apply it to all the files.
thasmartuno: it's just what i'm looking for. it's not important that it writes the tags, i only need to get the songnames. Please tell me where to find this module

well waty, it is a solution, but i'll stick to my own for now since is is more reliable. only thing left is to see if ThaSmartUno finds out something. if he does not, you will be given the points.

it doesn't write to the file ... but it does read the ID3 tag ... not the file name itself
oh ... i don't know ... i could upload it ... and its a dll not a module ... i didn't read your comment =) ... if u want me to upload it ... just ask
ASKER
well.. if it does not read the filename, only the tag, it's no use..
what shall we do then ?
waty: just answer, and i'll give you the points.
