it must be near the end of the file, because of the way it works. 
Furthermore if you use BruteFIR to perform the deconvolution you should 
consider that BruteFIR truncates the output to make it the same lenght of 
the input, where the full convolution of a signal of length N with a filter 
of length M would yeld a signal of length N+M-1. To avoid this truncation 
simply add some seconds of silence to the recorded signal before performing 
the convolution (the scripts I sent you already did it).
