The latest version of the Linux sound server and multimedia framework, Pipewire 1.4, has been released by lead developer Wim Taymans. It is already available in distributions such as Arch Linux and Fedora Rawhide, also expected to be included in Debian’s upcoming version "Trixie". While it missed the cutoff for Ubuntu 25.04, Debian users can look forward to its enhancements, particularly for MIDI sequencers and hard disk recording.
Initially developed as a video stream processing framework, Pipewire has evolved to replace Pulse Audio and JACK Audio, providing a streamlined setup for audio management. With version 1.4, it introduces a control API compatible with applications utilizing JACK. This version enhances MIDI support by offering an interface for Universal MIDI Packet (UMP), allowing for real-time conversion from MIDI 1.0 to the newer protocol.
Pipewire 1.4 offers significant benefits for general audio playback as well. It prioritizes audio players as real-time clients and combines their configuration with ALSA plug-ins. New high-resolution audio codecs like DSD are now supported, as well as Bluetooth codecs for VoIP systems, enabling complex audio routing.
The inclusion of new features extends to video streaming, where users can now apply filters via FFmpeg. A new processor platform based on RISC-V has also been added, promising improvements for users on this architecture.
