Exchangeable image file format is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras, scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing encoding formats with the addition of specific metadata tags: JPEG lossy coding for compressed image files, TIFF Rev. 6.0 for uncompressed image files, and RIFF WAV for audio files. It does not support JPEG 2000 or GIF encoded images.
ID3 is a metadata container most often used in conjunction with the MP3 audio file format. It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself.
Discogs is a website and crowdsourced database of information about audio recordings, including commercial releases, promotional releases, and bootleg or off-label releases. While the site was originally created with a goal of becoming the largest online database of electronic music, the site now includes releases in all genres on all formats. After the database was opened to contributions from the public, rock music began to become the most prevalent genre listed.
The following comparison of video players compares general and technical information for notable software media player programs.
ReplayGain is a proposed technical standard published by David Robinson in 2001 to measure and normalize the perceived loudness of audio in computer audio formats such as MP3 and Ogg Vorbis. It allows media players to normalize loudness for individual tracks or albums. This avoids the common problem of having to manually adjust volume levels between tracks when playing audio files from albums that have been mastered at different loudness levels.
Amarok is a free and open-source music player. It is available for Unix-like, as well as for Windows and macOS systems. Although Amarok is part of the KDE project, it is released independently of the central KDE Software Compilation release cycle. Amarok is released under the terms of the GPL-2.0-or-later.
APE tags comprise one extant convention used to store information (metadata) about a given digital audio file. Each APE tag constitutes a discrete element that describes a single attribute of the file's contents. Each consists of a key/value pair; the key is simply a label that names the attribute, such as Year, Title, Artist, or Track Number, etc.), and associated with it is a corresponding value, namely, some information descriptive of this file, in terms of the attribute in question. APE tags can be used with .ape-formatted recordings, as well as with sound files of other audio file formats.
M3U is a computer file format for a multimedia playlist. One common use of the M3U file format is creating a single-entry playlist file pointing to a stream on the Internet. The created file provides easy access to that stream and is often used in downloads from a website, for emailing, and for listening to Internet radio.
Music Player Daemon (MPD) is a free and open music player server. It plays audio files, organizes playlists and maintains a music database. In order to interact with it, a client program is needed. The MPD distribution includes mpc, a simple command line client.
Flash Video is a container file format used to deliver digital video content over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. There are two different Flash Video file formats: FLV and F4V. The audio and video data within FLV files are encoded in the same way as SWF files. The F4V file format is based on the ISO base media file format, starting with Flash Player 9 update 3. Both formats are supported in Adobe Flash Player and developed by Adobe Systems. FLV was originally developed by Macromedia. In the early 2000s, Flash Video was the de facto standard for web-based streaming video. Users include Hulu, VEVO, Yahoo! Video, metacafe, Reuters.com, and many other news providers.
A Vorbis comment is a metadata container used in the Vorbis, FLAC, Theora, Speex and Opus file formats. It allows information such as the title, artist, album, track number or other information about the file to be added to the file itself. However, as the official Ogg Vorbis documentation notes, “[the comment header] is meant for short, text comments, not arbitrary metadata; arbitrary metadata belongs in a separate logical bitstream that provides greater structure and machine parseability.”
A tag editor is a piece of software that supports editing metadata of multimedia file formats, rather than the actual file content. These are mainly taggers for common audio tagging formats like ID3, APE, and Vorbis comments, but can also be taggers for JPEG, PDF and TIFF metadata.
Jaikoz is a Java program used for editing and mass tagging music file tags.
MP3Gain is an audio normalization software tool. The tool is available on multiple platforms and is free software. It analyzes the MP3 and reversibly changes its volume. The volume can be adjusted for single files or as album where all files would have the same perceived loudness. It is an implementation of ReplayGain. In 2015 Debian and Ubuntu removed it from their repositories due to a lack of an active maintainer.
Mp3tag is a metadata tag editor that supports many audio file formats. It is freeware for Microsoft Windows, while it costs €20 for Apple macOS.
aTunes is a free and open source audio player with MPlayer as its playback engine. aTunes supports MP3, Ogg Vorbis, FLAC and other formats. aTunes allows users to edit tags, organize music and rip audio CDs easily.
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.
Puddletag is a graphical audio file metadata editor ("tagger") for Unix-like operating systems.
Kid3 is an open-source cross-platform audio tag editor for many audio file formats. It supports DSF, MP3, Ogg, FLAC, MPC, MPEG-4 (mp4/m4a/m4b), AAC, Opus, SPX, TrueAudio, APE, WavPack, WMA, WAV, AIFF, tracker modules.
fre:ac is a free audio converter and CD extractor for Windows, Linux, macOS, and FreeBSD, distributed under the GPL-2.0-or-later.
