PipeWire is a server for handling audio, video streams, and hardware on Linux. [ 2 ] [ 3 ] [ 4 ] It was created by Wim Taymans at Red Hat . [ 5 ] [ 6 ] It handles multimedia routing and pipeline processing.
The application originally used the Pulseaudio sound server as it allowed effects to be added to audio streams with ease, [4] however, now runs exclusively on the PipeWire sound server after a port in 2021. [5] It is published under the GPL-3.0-or-later license. [2]
It is possible for JACK and PulseAudio to coexist: while JACK is running, PulseAudio can automatically connect itself as a JACK client, allowing PulseAudio clients to make and record sound at the same time as JACK clients. [36] PipeWire is an audio and video server that "aims to support the use cases currently handled by both PulseAudio and Jack".
ALSA is part of the Linux kernel, while PulseAudio is middleware, a part of the lower levels of the desktop stack. So is SDL . Advanced Linux Sound Architecture ( ALSA ) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers .

On a low-end machine, such as a 600 MHz C3, the pulseaudio server can use 30% of the CPU. This converts a silent media-server from one which can (just) play DVDs into one which can't. Most pulseaudio-compliant applications such as mplayer will happily fall back to using ALSA natively if p.a. is uninstalled.

LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.
