Next Generation Sound System

PulseAudio is the current defacto standard audio system for Linux-based operating systems. It allows advanced operations on sound data as it is passed between applications and system hardware, such as on-the-fly redirection of audio output from speakers to a bluetooth headset, smart audio volume management, sample format or channel count conversion and combination of several sounds into one. This, and much more is easily achieved using PulseAudio.

Why PulseAudio?

With today's focus on convergence devices, where mobile phones, tablets, set top boxes, media servers and similar all seem to merge together, having an advanced high quality audio system is critical in order to launch a successful product.

Supported by top tier vendors and a vibrant community of developers, PulseAudio has established itself as the leading sound system standard on Linux and Unix-like systems. It has found adoption in all major Linux distributions as well as a number of embedded devices such as the Nokia N900/N9 and the HP Pre3 and Touchpad.

Key features that make PulseAudio a versatile choice for a host of products include:

• Dynamic latency adjustment to provide low-latency or low-power, as required by applications
• Flexible routing to deal with a spectrum of simple to complex devices and use-cases
• A powerful powerful module system to make extending PulseAudio for specific purposes easy
