Hello.  I recently had a contribution turned down (it had no votes for or against).  I think it's probably because I was a bit flippant  with respect to what I put to justify the change I'd included from stereo to mono. ("Well it sounded mono to me".)  Normally I've put a bit more about listening to the film, its music, foreground and background noise, etc with headphones on which seems to have been sufficient proof in the past.  But I was tired... wanted to go to bed...

However, it got me thinking, how do you easily demonstrate that a film is mono?  I often see films with their audio marked incorrectly as Stereo, presumable because of the way the sound has been coded onto the disk so it gets labelled by PowerDVD, AV amps etc as stereo, so it is quite a noticeable problem within the online database.  There must be a way that's more scientific than just listening to it carefully.

Thanks.

Well, MonoCheck may sometimes be helpful, but it is far from perfect. It displays the difference in level between the two tracks. In theory that should be zero for mono tracks. But theory and practice are two different things. If it does stay at or near zero, that's a good indicator that it is indeed mono. If it doesn't - you just don't know.

You could check IMDb and see if the original sound was mono. If it was, and there is no mention of any remastering of the soundtrack, then that's also a good indicator that it's mono.

But if you're looking for a foolproof way to determine mono, then I think you're out of luck.

You truly are a person of wonder!  Thank you so much.  I'll enjoy trying your programme out.
