This opcode can be used for monitoring the output signal from csound. It should not be used for processing the signal further.
See the entry for the fout opcode for an example of usage of monitor.
Here is an example of the monitor opcode. It uses the file monitor.csd.
Example 524. Example of the monitor opcode.
See the sections Real-time Audio and Command Line Flags for more information on using command line flags.
