function gowave2(wavefile,C)

%gowave2  
%
%   gowave2(wavefile,C) reads from a wavefile to simulate
%   a stream of audio data.  It breaks the signal into
%   blocks, processes them,  and displays the possible
%   source positions to a plot.  The blocks overlap by
%   half of a block size, so no impulse is lost because it
%   fell between blocks.
%
%   See also: maxt, fshift, go2, twomicplot, blargh3.

% NOTE: should take in a STEREO wavefile
% C is the distance between microphones
