PulseAudio: Open Source Sound Server for Linux
Open source sound server for Linux, routes audio from applications to audio devices, multiple app support, audio volumes control, network streaming, device hotplug detection
What is PulseAudio?
PulseAudio is an open source sound server designed for Linux operating systems. It serves as an intermediate layer between audio applications and the audio hardware, providing features like:
- Audio routing - Allows routing audio from applications to different audio devices like speakers, Bluetooth headsets, USB headphones etc.
- Concurrent access - Multiple applications can access the soundcard concurrently through PulseAudio.
- Volume control - Per application and per device volume can be controlled from a central location.
- Network transparency - Audio from one machine can be redirected to another machine easily using networked PulseAudio.
- Flexible device management - Devices like Bluetooth headsets can connect/disconnect transparently to applications.
- Low latency for applications like gaming voice chat.
Some key advantages of using PulseAudio include simplified audio management for both end users and application developers, avoiding hardware conflicts between multiple audio apps, network streaming support, low latency operation etc. It is used in many Linux distributions like Ubuntu, Fedora, Debian etc. as the default sound architecture.
