Export total length of mp3 files in a folder?

Question

I have many folders of mp3 files, and I would like to have a list of the combined duration of all the mp3s in each folder. That would be the ideal solution, but some means of doing a directory print attaching the individual mp3 duration would also be good. Any help would be much appreciated. I am running Windows 7 Home Premium, but have access to a number of other Windows/Mac OS.

Edit - I actually found an solution using the export function in the freeware program Tagscanner.

If you're working on Mac OS or any Unix system you can install ffmpeg and use the following command to extract the duration of a single file:

ffmpeg -i filename.mp3 2>&1 | egrep "Duration" | cut -d ' ' -f 4 | sed s/,//

That would for example return "00:08:17.4".

You can use this in a shell script of course, so for example this would list all of the mp3 files in a folder and their duration to the right.

#!/bin/bash
# call me with mp3length.sh directory
# e.g. ./mp3length . 
# or ./mp3length my-mp3-collection

for file in $1/*.mp3
do
    echo -ne $file "\t"
    ffmpeg -i "$file" 2>&1 | egrep "Duration"| cut -d ' ' -f 4 | sed s/,//
done

You can add a column to the file list in Wİndows Explorer. Add "Length" property colum to folder. Then select all off the mp3 files in the folder. You can see total length in the bottom summary pane of win.exp...

(Not the whole solution to your question but you said "any help would be appreciated :D)

or in windows- use directx "audiovideo" obejct a c# project, use a foreach loop for each item in the list adding the length property for every track. sounds like a fun project :)
