-% Can adjust levels of multichannel files (if comment is taken out). 
-% Does adjustment for mean power over channels. target_level defines 
-% the mean target level in dB.
-% Note that _no_ per-channel adjustment, but an overall adjustment is
-% achieved with this function.
-% Main functionality is calculating rms before and after adjustment.
