a strange file

[295126748]

Hello,

This is a ogg file on my pc

37_fadegirl_start.zip

(121.29 KiB) Downloaded 148 times

Everything show the Audio Bit Rate of it is

4294967 kbps

I have tried an other audio editor , it shows 0 bit

I felt strange
Perhaps this file is a broken oggfile?

[void]

4294967 kbps is the average bitrate (nominal bitrate) stored in the header of this ogg file.

Everything will report this average bitrate as the Audio Bit Rate.

Code: Select all

Overall bit rate mode                    : Variable
Overall bit rate                         : 270 kb/s
Writing application                      : Adobe(R) Audition(R)

ffprobe (ffmpeg) says:

Code: Select all

  Duration: 00:00:03.74, start: 0.000000, bitrate: 270 kb/s
  Stream #0:0: Audio: vorbis, 96000 Hz, stereo, fltp, 4294967 kb/s
    Metadata:
      ENCODER         : Adobe(R) Audition(R)

It might ? be this, What is the difference of duration bitrate and stream bitrate in ffmpeg/ffprobe??

not Overall bit rate.it is something called Audio Bit Rate

4294967 is too large.
common files will be 50,100kb,150kb ,roughly more or less

MediaInfo cannot read Audio bit rate of this file ,while can read Audio bit rate of other ogg files
ffmpeg can read it ,but it and says 4294967 kbs

So I guess the head of the ogg is broken or has been artificially modified?

[void]

Yes, the bit rate stored in the header is incorrect.

Everything will use the value stored in the header.

I’ve got it.

Thank you Void and Therube：）
