jack-netbridge 0.2.0

Send and receive Jack MIDI data as multicast streams over network.

jack_netbridge

jack_netbridge is a Python tool to send and receive Jack audio and MIDI as multicast network streams. This is useful for transmitting audio or MIDI over a network with minimal latency using the JACK audio system.

Installation

pip install jack-netbridge

Usage

usage: jack_netbridge [-h] [-c CONFIG]

jack_netbridge: send/receive Jack audio and MIDI as multicast streams

options:
  -h, --help                      Show this help message and exit.
  -c CONFIG, --config CONFIG      Path to the configuration file.

Configuration file example

By default jack_netbridge will look for the ~/.jack_netbridge.toml file to read configuration. Each section in the TOML file describes a client and a port with arbitrary names, separated by :.

Configuration example:

["audio_recv_L:out"]
type = "AudioReceiver"
multicast_group = "239.0.0.1"
multicast_port = 4023
multicast_ttl = 2
interface_name = "eth1"

["audio_recv_R:out"]
type = "AudioReceiver"
multicast_group = "239.0.0.1"
multicast_port = 4024
multicast_ttl = 2
interface_name = "eth1"

["midi_recv_R:in"]
type = "MidiTransmitter"
multicast_group = "239.0.0.1"
multicast_port = 4025
multicast_ttl = 2
interface_name = "eth1"

Troubleshooting

• Garbled audio: make sure that both sample rate and buffer size are identical for both receiver and transmitter.

• No data sent or received: check if the current multicast group is sent / received on the right interface, e. g by checking ip route output.
