jack-tools binary package in Ubuntu Bionic i386

 jack-tools is a collection of small tools for the JACK Audio Connection
 Kit.
 .
 JACK allows the connection of multiple applications to an audio device,
 as well as allowing them to share audio between themselves.
 .
 jack-dl loads dsp algorithms from shared libraries. Commands are sent
 as OSC packets over a UDP connection.
 .
 jack-record is a light-weight JACK capture client to write an arbitrary
 number of channels to disk.
 .
 jack-scope draws either a time domain signal trace or a self
 correlation trace. Multiple input channels are superimposed, each
 channel is drawn in a different color. jack-scope accepts OSC packets
 for interactive control of drawing parameters.
 .
 jack-osc publishes the transport state of the local JACK server as OSC
 packets over a UDP connection. jack-osc allows any OSC enabled
 application to act as a JACK transport client, receiving sample
 accurate pulse stream timing data, and monitoring and initiating
 transport state change.
 .
 jack-plumbing maintains a set of port connection rules and manages
 these as clients register ports with JACK. Port names are implicitly
 bounded regular expressions and support sub-expression patterns.
 .
 jack-udp is a UDP audio transport mechanism for JACK. jack-udp is
 obsolete: use net driver instead.
 .
 jack-play is a light-weight JACK sound file player. It creates as many
 output ports as there are channels in the input file.
 .
 jack-transport is a JACK session manager. It reads configuration
 information from a system wide and a user specific configuration file
 and manages sessions involving the JACK daemon proper and optionally a
 set of secondary jack daemons.
