About:
qjackctl provides a graphical user interface for the JACK Audio Connection Kit, allowing users to start and stop the JACK daemon, connect audio and MIDI ports between applications, and monitor audio routing visually. It serves as an essential control panel for managing low-latency professional audio workflows on Linux and other Unix-like systems.

Key Features:

Graphical patch bay for connecting audio and MIDI ports
Real-time monitoring of JACK server status and latency
Transport controls for synchronizing audio applications
ALSA, FireWire, and OSS backend configuration

Use Cases:

Setting up audio routing between a DAW and external synthesizers
Monitoring and managing professional audio recording sessions
Configuring low-latency audio for real-time processing

Alternatives:

Patchage – Lightweight patch bay focused purely on connections, lacks server controls
Carla – Advanced plugin host with built-in patch bay, more complex but feature-rich
