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. ATTRIBUTES
