Sample file:
https://www32.zippyshare.com/v/aBw5JUeB/file.html
When FFmpeg parses the header the samplerate is detected as 44100hz. But
in reality the audio is actually 32000hz. So seems like an incorrect value
in the header.
MediaInfo correctly detects it as 32000hz. I can't find the relevant piece
of code in its source, so I can't say how it determined that value.
The file has 2 channels and bitrate in header is 128000. So maybe
samplerate could be calculated based on that?
128000 (bitrate) / 2 (channels) / 2 (16 bits per sample) = 32000
