👉 DSP stands for Digital Signal Processing, which in this context refers to signal processing technology used in digital audio, video, and multimedia applications. The LIRC (Listen In IRC) command sets the default server on your computer's network interface to listen for incoming connections from other computers. This is commonly used when you're playing music or broadcasting a podcast on an external device. DSP-A970.lircd.conf is a configuration file that defines how and where to listen for incoming connections, so that listeners can easily connect and enjoy your music or video content. The path "/etc/lircd" indicates the directory in which this file is located on your system.
