| | Posted: | | | | I have a feeling that this has been asked before, but I couldn't find any answer, so apologies if it has... I recently switched to a new computer with Windows Vista. My old one came with PowerDVD 4, the new one came with PowerDVD 7. The old version could differentiate between Dolby Stereo and Dolby Surround, but as far as I can tell, no version after PowerDVD 4 does that. Seems really strange unless the old version was giving incorrect results...  Anyhow - is there any software out there (preferably freeware) that can tell if an audio track is Stereo or Surround? I have tried a couple, and none seem to be able to do it. | | | My freeware tools for DVD Profiler users.

| | Posted: | | | | There is no software that can detect dolby surround. PowerDVD 4 can only detect the presence of the dolby surround flag on the track, which is good enough for me but is sometimes wrong. Specially since the surround flag has three states (yes, no, maybe) and is sometimes wrong. I still use PowerDVD 4 but have been told that either VobEdit or IfoEdit should also be able to read this flag. Can't remember which of the two. |

| | Posted: | | | | DVD Audio Extractor can read if it has a "surround flag" on the audio track. This is not always accurate however, since some studios even do that with Mono audio tracks. Anchor Bay is particularly bad about that. | | | | Corey |

| | Posted: | | | | Thanks guys,
Follow up question: I understand that it doesn't have to be Surround even if it is flagged as such, but does the opposite also hold true. That is, can it be Surround even if the flag says "no"?
If one can trust a "no flag", then at least half the battle is won... | | | My freeware tools for DVD Profiler users.

Stuart You are right, except that I'm exasperated by this guy that pursue me on all forums calling me Yves as if he was my friend, but whose only purpose is to denigrate my positions since he does not like them. I tried not to answer his attacks, but since they didn't stop, I went so far as to do the same... | | | | Images from movies |

He is pretty much omnipotent (or omimpotent some might say given recent form  ), and could do with showing more consideration, but that's the way it is. What's important is that you can see it was uncalled for, and that makes you a better man. I'd offer you a beer, but it's a long (and damp) walk.  Stuart | | | This is a sig... ... ... yay...

Yeah, I was going to add " how does everyone know your name ( Yves) when it isn't in your tagline or signature?? But getting back to the question.. How tro detect surround... ?? Two ways (easy off the top). 1. Sit between all five speakers and use your ears as referance. 2. Hook up to a 5.1/dolby surround amp; and most video-audio amps will 'flag' the rear speakers as 'on' when it is set in 5.1 mode, or dolby surround. If the sound is only DD2 the amp will only flag the front two speakers, as stereo or 2 channel mono output. | | | In the 60's, People took Acid to make the world Weird.

| | Posted: | | | | Thanks widescreen, but that's not really the answer I was looking for.
I do my Profiler work on my PC (obviously), and I don't want to run out to my living room and fire up my home theater just to find the correct audio configuration for a certain title. And unfortunately my Pioneer amp does not flag the rear speakers, so it would be ears only and that's not very reliable. | | | My freeware tools for DVD Profiler users.

| | Posted: | | | | PowerDVD doesn't see the Surround Flag. Use DVD Audio Extractor for that info, it will see the 3 channel flag and report it.  | | | In the 60's, People took Acid to make the world Weird. Now the World is weird and People take Prozac to make it Normal.

PowerDVD doesn't see the Surround Flag. Yes it does! But you need to open the/a VOB file directly, rather than playing the DVD from the drive. Just browse to the Video_TS folder on the DVD and double-click one of the large files. Then you should see the flag. Only minor annoyance is, that next time you open PowerDVD you need to switch the source back to the DVD drive. | | | Achim [諾亞信； Ya-Shin//Nuo], a German in Taiwan.

You mean it does detect the surround flag, but it just doesn't tell you in normal play??? Geez, how stupid is that!? | | | My freeware tools for DVD Profiler users.
