Hi, if the items are grouped like in your sample, try something like:
Code:
awk '
  function pr(i) {
    printf "%s", i A[i]
    print  i, "TOTAL", T[i]
  }
  {
    if(i!=$1 && NR>1) pr(i)
    i=$1
    $1=x
    A[i]=A[i] $0 ORS
    T[i]+=$3
    GT+=$3
  }
  END {
    pr(i)
    print "", "TOTAL", GT}
' OFS='\t' file

Otherwise, try something like this:
Code:
awk '
  {
    i=$1;
    $1=x
    A[i]=A[i] $0 ORS
    T[i]+=$3
    GT+=$3
  } 
  END {
    for(i in A) {
      printf "%s",i A[i]
      print  i, "TOTAL", T[i]
    }
    print "", "TOTAL", GT
  }
' OFS='\t' file

But then the items will not necessarily appear in the order of the input file

SYNOPSIS

       zita-resampler <options> <input file> <output file>.

       Zita-resampler is a simple resampling application written with the libzita-resampler library.

       Input  format  is  any  file  readable by libsndfile, output is either WAV (WAVEX for more than 2 channels)  or CAF. Apart from resampling,
       users can change the sample format to 16-bit, 24-bit or float, and for 16-bit output, add dithering.

       Available dithering types are rectangular, triangular and Lipschitz' optimised error feedback filter.

OPTIONS

       --help Display this text.

       --caf, --wav, --amb
	      Output file type.

       --rate <sample rate>
	      Output sample rate.

	      Output sample format.

       --rec, --tri, --lips

       The default output file format is wav, 24-bit, no dithering.  Integer output formats are clipped, float output is not.
