NAME

       trx-tx - real-time audio receiver over IP

SYNOPSIS

       trx-tx [-d DEV] [-m MS] [-h ADDR] [-p PORT] [-j MS] [-r RATE] [-c N] [-v N] [-v FILE]

DESCRIPTION

       trx-tx transmits real-time audio over IP from an ALSA audio device.

OPTIONS

       -d DEV The alsa device name. Default is 'default'

       -m MS  Set the buffer time. Default is 16 milliseconds

       -h ADDR
              Set the IP address to listen on. Default is ::

       -p PORT
              Set the UDP port to listen on. Default is 1350

       -r RATE
              Set the sample rate. Default is 48000Hz.

       -c N   Set the number of channels. Default is 2.

       -f N   Set  the frame size. Default is 960 samples. The allowed frame sizes are defined by
              the Opus codec. For example at 48000Hz, the permitted values are 120, 240,  480  or
              960.

       -b N   Set the approximate bitrate. Default is 128.

       -v N   Set the verbosity level. Higher N implies more verbosity. Default is 1.

       -D FILE
              Run the receiver as a daemon, writing the process ID to FILE.

NOTES

       The  Debian package has renamed the upstream binary tx to trx-tx as it is less generic and
       less likely to collide with other packaged binaries.

EXAMPLE

       To receive audio being sent to the local interface with the IP address 239.0.0.1  use  the
       following:

              trx-tx -h 239.0.0.1

                                                                                        TRX-TX(1)
