Left/Right channel : Detect dual stereo (Mono) content in wav

[Dark-Cracker]

hi,

i want to know if a wav is a dual stereo (a mono content upmix to stereo).

For this i want to check is some left channel sample are the same than in the right channel.

my first question :

1) Do you think this way to detect dualstereo content is working ?

2) When i get my sample (by reading in binary the wav file) how to differenciate the left and right channel ?

i have heard it's interleaved, so the odd samples number are left channel and even samples number are right channel ?

any help is welcome :)

Bye.
