The samples are interlaced and alternate between left and right, yes. 0 
is left, 1 is right, 2 if left, 3 is right, etc.

Separate in what way? Do you just need to address the channels 
individually, or do you actually need to deinterlace the samples (so 
left and right go into separate buffers)? If you just need to address 
the channels individually, you can do:

l_buffer[(sample*2) + 0]; // left
l_buffer[(sample*2) + 1]; // right

to read the left and right channels of the given sample.
