> Any suggestions on how to go about this? No audio domain specific related experience, so there may be something better for this, but, failing that, for format exploration at least, I'd think numpy/scipy+jupyter would be great for interactively mucking around with the bits/bytes e.g. np.where(x > ((max(x) - min(x)) / 2)) (roughly, am a bit rusty at the moment) basically gives you a boolean array containing approximate zero crossings in an array, and so on. similarly, you could subslice on range boundaries to ignore imagined 'marker' bits, index this through an ASCII table & display results, etc. if you're not up with numpy array syntax / dtypes it takes a bit of getting used to, but well worth the effort IMHO in terms of the overall data exploration skills gained
