Audiocodec in Video Problem (mp3/mp4)

[diocloid]

Hello, this is my first post, so if this doesn't belong here I'm deeply sorry.

My Problem:
I was recording a Livestream with the "open Broadcaster Software" and upon reviewing the footage I realized that the sound didn't play.


The Encoding settings for the audio are mp3 128bit.
The File itself is a mp4 File


MediaInfo has this to say:

Premiere Pro doesn't recognize the audio, VLC crashes and Audacity can't open the file.
Only the SMPlayer plays both audio and video correctly.


Is there a way to 'save' the recording (extract the sound for further editing)?


Every little bit of help is greatly appreciated
Best wishes

Try demux/extract the audio with mymp4boxgui or Pazera Free Audio Extractor.
