NAME
     passthru - pass audio sample data from an input port to an output port

SYNOPSIS
     passthru [-h][-v][-n nchannels][-s samplefmt][-r rate]
	  [-b blksize][-q qsize][-e]

DESCRIPTION
     Passthru opens an audio input port and an output port, and connects them.
     Command line options allow the user to experiment with the various audio
     port parameters.

     -h	  help: print out a list of command line options and their
	  descriptions

     -v	  verbose: output to stdout

     -n	  number of channels: 1 = mono, 2 = stereo

     -s	  sample format: 8, 16, or 24 bit

     -r	  sample rate: 48000, 44100, 32000, etc

     -b	  transfer blocksize: specify value in sample FRAMES

     -q	  queuesize for each of the two audio ports: specify value in SAMPLES

     -e	  error reporting: display error status of audio ports

     Larger transfer blocksizes decrease the CPU load but they also cause
     larger latency from input and output.
