PulseAudio

PulseAudio is a sound server for POSIX and UNIX-like computer systems. It acts as a proxy to other sound servers, allowing for fine-grained control over sound devices and streams. It is commonly used in Linux distributions to manage audio input and output.

This software is designed for developers, system administrators, and advanced users who require a robust and flexible audio management solution. It enables features such as network audio, per-application volume control, and mixing of multiple audio streams.
