fixed a lil' "feechah":
Code:
# if the number of fields is 6
NF == 6 {
   # add to running tally of sum the value of the last (NF) field
   sum+=$NF
   # concatenate the current line to the running record of the previously encountered lines of 6 fields
   rec=(rec)?rec ORS $0 :$0
   # go to the NEXT line
   next
}
{
   # if the running record (rec) is NOT empty
   if (rec) {
   # print the 'summary line' (the line with 5 fields) followed by the sum
   # (sum) and followed by ORS (new line by default)
     print sumLine OFS sum
   }

   # reset the sum to 0 and rec to empty string
   sum=0; rec=""
   # assign the current line ($0) to a variable sumLine
   sumLine=$0
}
END {

# take of the trailing record - same logic as before
  if (rec)
    print sumLine OFS sum
}

play

play(1) 						      General Commands Manual							   play(1)

NAME

       play - play any sound file to audio device

       rec  - record audio to any sound file format

SYNOPSIS

       play [fopts] infile [effect]

       rec [fopts] outfile [effect]

DESCRIPTION

       This manual page briefly documents the play and rec commands.

       play  and  rec are programs that allow you to play and record different types of sound files from the command line.  They are front ends to
       the more general sox(1) package.  Normally, the play command will automatically detect the type and other parameters of the  soundfile.	If
       it can't do so, the parameters can be changed through options.

OPTIONS

       A summary of common options are included below.	For a complete description of options and their values, see the sox(1) man page.

       -c [channels], --channels=[channels]
	      Define the number of channels in the file.

       -d [device], --device=[device]
	      Specify a different device to play the sound file to.

       -f [format], --format=[format]
	      Specify bit format of the sample. One of s, u, U, A, a, or g.

       -r [rate], --rate=[rate]
	      Specify the sample rate of the audio data (samples per second).

       -s [size], --size=[size]
	      Specify the width of each sample.  One of b, w, l, f, d, or D.

       -t [type], --type=[type]
	      Specify audio file format to use.  Useful if it can not be automatically determined.

       -v [volume], --volume=[volume]
	      Change the audio volume

       -x , --xinu
	      Reverse the byte order of the sample (only works with 16 and 32-bit data).

       -h, --help
	      Show summary of options.

       --version
	      Show version of play/rec.

       Description of effects are described in the
	      sox(1) man page.
