Sound File Reports Wrong Information

Hi all

I have a sound file that reports it's only 880k big and 13 seconds long.
If I pay it in a media player, it's actually a few minutes. I also suspect it isn't actually 880k big as it's around 300kbps. I read VBR songs, if encoded incorrectly, use the first bits of the file to display it's time length.

Found this: VBRFix new version: Corrects Stream Length bug

but the program doesn't work, despite it saying it has.

I have others that report being 30+ minutes but are less than 5.

Is there anything I can do?

I zipped the file (attached).
Right-click and see the properties. However, when you actually play it, the file time length is completely different.

File Explorer shows 13 seconds.
Groove Music plays 13 seconds.
Audacity opens it and plays 13 seconds.
FFmpeg shows:

Code:

 Metadata:
    album           : Kalax
    artist          : Kalax
    genre           : Electronic
    title           : Time Lapse
    track           : 1
    date            : 2017
  Duration: 00:00:13.56, start: 0.023021, bitrate: 539 kb/s
    Stream #0:0: Audio: mp3, 48000 Hz, stereo, s16p, 310 kb/s

Converting it using FFmpeg to another file make a 13 second long copy.

Whatever you are playing after the 13 seconds is up is not in this file, somehow it's linking to another when you play it?

Hmm.
Maybe that wasn't the file I was looking at through an audio program.

However, I have tested this one (attached) and it really does distort the time. However, ran it through the program I linked to and it worked this time.

Will mark as solved though as the program did correct it.

That one reports 1:58 in Properties, but is actually 1:50 when played. Converting with Ffmpeg gives a copy that's 01:49.82 long. I have seen small discrepancies like this before - a few seconds difference between 'properties' and actual play time, even on some of my own recordings.

Does it report the low kbps because it's a variable bitrate file?
So that program just looks at the first section and decides it's all the same?
