APE Tag
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 , , , or , etc.), and associated with it is a corresponding value, namely, some information descriptive of this file, in terms of the attribute in question (e.g., for ). APE tags can be used with .ape-formatted recordings, as well as with sound files of other audio file formats. Essence A sound file, such as an .ape- or .mp3-formatted file, may, in addition to its payload audio data, also contain metadata that provide descriptive or statistical information about its audio content. When APE (v1) tags are used, they will appear at the end of the file, following the data; i.e., the digitized audio stream. Placing the tags at the end of the file, rather than at the beginning, ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

WavPack
WavPack is a free and open-source lossless audio compression format and application implementing the format. It is unique in the way that it supports hybrid audio compression alongside normal compression which is similar to how FLAC works. It also supports compressing a wide variety of lossless formats, including various variants of PCM and also DSD as used in SACDs, together with its support for surround audio. Features WavPack compression can compress (and restore) 8-, 16-, 24-, and 32-bit fixed-point, and 32-bit floating-point PCM audio files in the .WAV file format. It also supports surround sound streams and high sampling rates. Like other lossless compression schemes, the data reduction rate varies with the source, but it is generally between 30% and 70% for typical popular music and somewhat better than that for classical music and other sources with greater dynamic range. Hybrid mode WavPack also incorporates a "hybrid" mode, which still provides the features of ...

Sound Production Technology
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of acoustical e ...

Puddletag
Puddletag is a graphical audio file metadata editor ("tagger") for Unix-like operating systems. It is free and open-source software subject to the terms of the GNU General Public License (GPL) version 3. In most major desktop Linux distributions, it is available from standard package repositories. Under Arch Linux(-based ones) it can be obtained from community repositories. The user interface is modeled after the popular Windows freeware ''Mp3tag''. It uses a spreadsheet-like layout so that all the tags a user may want to edit by hand are visible and easily editable. All the other audio taggers available for Linux take a different approach to user interface design. The interface elements can be freely arranged. In July 2008, the first version (0.1) was released via SourceForge. The website counted several thousand downloads for each release before the project finally left the platform in early 2016 and was included in the package sources of most major Linux distributions. Version ...

Tag Editor
A tag editor (or tagger) 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 (for example Windows Media Player and iTunes), but can also be taggers for JPEG, PDF and TIFF metadata (for example iPhoto). A common purpose of tag editors is to correct or update metadata and enable sorting and grouping of multimedia files, for example music collections. This often happens in a batch processing mode so that one doesn't have to manually edit every file on its own. Audio files editing techniques Manual Media players such as iTunes, Foobar2000 or Winamp, as well as dedicated tag editing programs allow users to manually edit tag and song file information, including composer and release year. Dedicated tag editors may feature batch processing and creating tags from file names and vice versa. Online music databases One type of ...

Foobar2000
foobar2000 (often abbreviated as fb2k or f2k) is a freeware audio player for Microsoft Windows, iOS and Android developed by Peter Pawłowski. It has a modular design, which provides user flexibility in configuration and customization. Standard "skin" elements can be individually augmented or replaced with different dials and buttons, as well as visualizers such as waveform, oscilloscope, spectrum, spectrogram (waterfall), peak and smoothed VU meters. foobar2000 offers third-party user interface modifications through a software development kit (SDK). foobar2000 supports many audio file formats, has many features for organizing metadata, files, and folders, and has a converter interface for use with command line encoders.

Winamp
Winamp is a media player for Microsoft Windows originally developed by Justin Frankel and Dmitry Boldyrev by their company Nullsoft, which they later sold to AOL in 1999 for $80 million. It was then acquired by Radionomy in 2014. Since version 2 it has been sold as freemium and supports extensibility with plug-ins and skins, and features music visualization, playlist and a media library, supported by a large online community. Version 1 of Winamp was released in 1997, and quickly grew popular with over 3 million downloads, paralleling the developing trend of MP3 (music) file sharing. Winamp 2.0 was released on September 8, 1998. The 2.x versions were widely used and made Winamp one of the most downloaded Windows applications. By 2000, Winamp had over 25 million registered users and by 2001 it had 60 million users. A poor reception to the 2002 rewrite, Winamp3, was followed by the release of Winamp 5 in 2003, and a later release of version 5.5 in 2007. A now-di ...

OptimFROG
OptimFROG is a proprietary lossless audio data compression codec developed by Florin Ghido. OptimFROG is optimized for very high compression (small file sizes) at the expense of encoding and decoding speed, and consistently measures among the highest compressing lossless codecs. OptimFROG comes with three compressors: one lossless codec for integer LPCM format WAVE files, one for IEEE_754 floating-point WAVE files, and a ''DualStream'' format with a lossy part and a correction file for losslessness. OptimFROG DualStream OptimFROG DualStream is a lossy codec, aimed to fill the gap between perceptual coding and lossless coding as OptimFROG DualStream has an option to produce a correction file. This file can be used, in combination with the main lossy-encoded file, for lossless decoding, but not, unlike Wavpack hybrid for instance, for playback. This correction feature is also offered by MPEG-4 SLS and DTS-HD Master Audio. Technical details Metadata The OptimFROG file formats use ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Digital Audio
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced analog audio technology in many areas of audio engineering, record production and telecommunications in the 1990s and 2000s In a digital audio system, an analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital signal, typically using pulse-code modulation (PCM). This digital signal can then be recorded, edited, modified, and copied using computer ...
