%F_RECORD: Record sound as an input vector

% Usage: [x,N,xm] = f_record (x,N,tau,fs,xm,xm_old,hc_type)
%
% Inputs: 
%         x    = an array of length N containing input samples
%         N    = number of input samples
%         tau  = duration of recording in seconds
%         fs   = sampling frequency
%         xm   = current value of input type
%         xm_old = previous value of xm
%         hc_type = an array of handles to input type radiou buttons
% Outputs: 
%          x    = an array of length N containing input samples
%          N    = number of input samples
%          xm   = current value of input type
