Hello Marc56us
I am using a code I found on the forum.
It's fast (0.7 seconds for over 5000 mp3s) but I don't know how to calculate the duration from what I retrieve.
Here is the code
Code: Select all
Fichier$ = OpenFileRequester("Sélectionner un fichier","","Musique (.mp3)",0)
If Fichier$
If ReadFile(0, Fichier$)
length = Lof(0) ; Lit la taille en octets du fichier
FileSeek(0, 1) ;
;Debug "Position: " + Str(Loc(0)) ; Affiche la position du pointeur
*MemoryID = AllocateMemory(30) ; alloue un bloc mémoire pour 10 octets
If *MemoryID
bytes = ReadData(0, *MemoryID, 30) ; Lit les 30 premiers caractères du fichier
Debug PeekS(*MemoryID)
EndIf
CloseFile(0)
EndIf
EndIf

Unfortunately, determining the duration of an MP3 file requires a bit more than just
reading a value and converting it into seconds / minutes.
Framesize, framecount, bitrate, sample rate and so on are also needed to calculate the time....
there are various formulas how it has to look like. and it will take longer than 0.7 seconds
Your 0.7 seconds when reading the directory with 5000 files is probably due to the fact that you
have already scanned the directory several times... something like this is buffered by Windows
and is always faster from the 2nd run onwards....
If I found my old source I will take it to the tips&tricks section....
Edit:
I found and post it.... :

@jack64
There is a good solution using VBS
Maybe some other fellow can do it
Or wait for me [After taking a nap]
