I'm looking for a way to check the audio bitrate of files that don't show the bitrate. I can't check the audio bitrate by right clicking the files like I usually do and I tried checking it with VideoSpec, FFmpeg and Spek, but it didn't work. When I tried checking the video file's audio bitrate with VideoSpec it looked like this:
Audio
Format: AAC - MPEG-4 audio
Bitrate: Undefined
Resolution: Undefined
Frequency: 48.0 KHz
Channel(s): 2 (stereo)
Channel(s) position: Front: L R
It says that the audio bitrate is undefined. Is there a way to check it? Any help would be appreciated.
