your text comparing doesn't makes sense to me. Please elaborate more
If you like to perform some action based in text value following code will help you
Code:
for var in none low medium high;
    do
        case $var in   
             none)      
                    <your statements here>
                    ;;   
             low)       
                     <your statements here>
                     ;;   
             medium)  
                    <your statements here>
                    ;;
             high)       
                    <your statements here> 
                    ;;

	    const mlib_f32 *low, const mlib_f32 *high, mlib_s32 n);

DESCRIPTION

       Each of these functions performs hard limiting.

       For monaural signals, the following equation is used:

	 dst[i] = low[0]	   if src[i] < low[0]
	 dst[i] = src[i]	   if low[0] <= src[i] < high[0]
	 dst[i] = high[0]	   if src[i] >= high[0]

       where i = 0, 1, ..., (n - 1).

       For stereo signals, the following equation is used:

	 dst[2*i] = low[0]	   if src[2*i] < low[0]
	 dst[2*i] = src[2*i]	   if low[0] <= src[2*i] < high[0]
	 dst[2*i] = high[0]	   if src[2*i] >= high[0]

	 dst[2*i+1] = low[1]	   if src[2*i+1] < low[1]
	 dst[2*i+1] = src[2*i+1]   if low[1] <= src[2*i+1] < high[1]
	 dst[2*i+1] = high[1]	   if src[2*i+1] >= high[1]

       where i = 0, 1, ..., (n - 1).

PARAMETERS

       Each of the functions takes some of the following arguments:

       dst	 Destination signal array.

       src	 Source signal array.

       srcdst	 Source and destination signal array.

       low	 Lower input limit. In the stereo version, low[0] contains the lower limit for channel 0, and low[1] contains the lower limit  for
		 channel 1.

       high	 Upper	input  limit.  In the stereo version. high[0] contains the upper limit for channel 0, and high[1] contains the upper limit
		 for channel 1.

       n	 Number of samples in the source signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
