Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder (codec) for lossy audio compression. Vorbis is most commonly used in conjunction with the Ogg container format and it is therefore often referred to as Ogg Vorbis.
Helix DNA is a project to produce computer software that can play audio and video media in various formats and aid in producing such media. It is intended as a largely free and open-source digital media framework that runs on numerous operating systems and processors and was started by RealNetworks which contributed much of the code. The Helix Community is an open collaborative effort to develop and extend the Helix DNA platform.
FLAC is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data.
A digital audio workstation (DAW) is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.
Rhythmbox is a free and open-source audio player software, tag editor and music organizer for digital audio files on Linux and Unix-like systems.
Airtime is a radio management application for remote broadcast automation, and program exchange between radio stations. Airtime was developed and released as free and open-source software, subject to the requirements of the GNU General Public License until it was changed to GNU Affero General Public License.
Sound Juicer is the official CD ripper program of GNOME. It is based on GTK, GStreamer, and libburnia for reading and writing optical discs. It can extract audio tracks from optical audio discs and convert them into audio files that a personal computer or digital audio player can play. It supports ripping to any audio codec supported by a GStreamer plugin, such as Opus, MP3, Ogg Vorbis, FLAC and uncompressed PCM formats. Versions after 2.12 implement CD playing capability. Last versions produce lossy formats with default GStreamer settings.
musikcube is a free and open-source cross-platform, terminal-based audio player software and streaming server.
FAAC or Freeware Advanced Audio Coder is a software project which includes the AAC encoder FAAC and decoder FAAD2. It supports MPEG-2 AAC as well as MPEG-4 AAC. It supports several MPEG-4 Audio object types, file formats, multichannel and gapless encoding/decoding and MP4 metadata tags. The encoder and decoder is compatible with standard-compliant audio applications using one or more of these object types and facilities. It also supports Digital Radio Mondiale.
Avidemux is a free and open-source software application for non-linear video editing and transcoding multimedia files. The developers intend it as "a simple tool for simple video processing tasks" and to allow users "to do elementary things in a very straightforward way". It is written in C++ and uses Qt for its graphical user interface, and FFmpeg for its multimedia functions. Starting with version 2.4, Avidemux also offers a command-line interface, and since version 2.6, the original GTK port has not been maintained and is now discontinued.
PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, various BSD distributions such as FreeBSD and OpenBSD, macOS, as well as Illumos distributions and the Solaris operating system.
LMMS is a digital audio workstation application program. It allows music to be produced by arranging samples, synthesizing sounds, entering notes via mouse or by playing on a MIDI keyboard, and combining the features of trackers and sequencers. It is free and open source software, written in Qt and released under GPL-2.0-or-later.
FluidSynth, formerly named iiwusynth, is a free open source software synthesizer which converts MIDI note data into an audio signal using SoundFont technology without need for a SoundFont-compatible soundcard. FluidSynth can act as a virtual MIDI device, able to receive MIDI data from any program and transform it into audio on-the-fly. It can also read in SMF (.mid) files directly. On the output side, it can send audio data directly to an audio device for playback, or to a Raw or Wave file. It can also convert a SMF file directly to an audio file in faster-than-real-time. The combination of these features gives FluidSynth the following major use cases:

The following comparison of audio players compares general and technical information for a number of software media player programs. For the purpose of this comparison, "audio players" are defined as any media player explicitly designed to play audio files, with limited or no support for video playback. Multi-media players designed for video playback, which can also play music, are included under comparison of video player software.
OBS Studio is a free, open-source, and cross-platform screencasting and streaming app. It is available for Windows, macOS, Linux distributions, and BSD. The OBS Project raises funds on the platforms Open Collective and Patreon.
GNOME SoundConverter is an unofficial GNOME-based free and open-source transcoder for digital audio files. It uses GStreamer for input and output files. It has multi threaded design and can also extract the audio from video files.
