# $1 : input G.723.1 bitstream file
# $2 : synthesized output speech file
# $3 : channel bitrate configuration file (this ASCII file contains the 8 allowed channel bitrates)
# $4 : channel bitrate (either fixed channel bitrate (e.g. 12000) or binary file with 16 bit
#			channel bitrate values for each 30 ms frame)
# $5 : number of frames (either specify "/f=[number of frames]" or a number. In the latter case
#                        this number specifies the entry to the error pattern and the whole file
#			 is processed)
