Fast way to detect STEREO / DUAL MONO?

[kypec]

I've been searching through the forums but couldn't find the answer.
Is there any tool or easy way to tell whether WAV audio track contains true stereo or just enhanced mono channels?
I have converted pile of old VHS tapes (TV series) with audio track being recorded as stereo. My father wanted to help me and did the same with his equipment, however, he messed a lot with settings and in the end he wasn't able to tell me which recording has been done as proper stereo and which as mono only.:stupid:
The only way I found so far is by trying to encode the track as Joint stereo MP3. If Lame reports both channels as 100% equal I know I have dual mono file.
Any comments and suggestions on better approach are welcome!:thanks:

Hi!

Load the videos (that contain the audiostreams) into GSpot...

I tell mono and stereo apart by ear... You may want to load the audio in audacity, it will show each channel and their profiles.

Maybe I'll try that. Anyway, I do not believe GSpot will be so clever that it will recognize both Left & Right channels as being 100% identical straight away.

Yes, I'm using Audacity for editing and post processing of audio material. I just wasn't able to find anything in there which could quickly analyze stereo track for channels (in)differences. Am I blind or Audacity has really no such feature?

don't read my answer as a joke, is easy to know if is stereo or mono:
open S.Forge or A.Audition(any audio editor or winamp)and see the file information...ok, can be stereo where Left channel is equal Right channel but opening the file in any program and using headphones if you hear something different between channels...no way, all doubts will go, is really stereo :)

With Goldwave is easy, maybe there are a equivalent method with Audacity.

Goldwave method:
1) Open the wav file and select all the Left channel (Edit -> Channel -> Left)
2) Edit -> Copy
3) Select all the Right channel (Edit -> Channel -> Right)
4) Effect -> Invert
5) Edit -> Mix (default)

Now you have the difference in Right channel.
