Advanced Audio Coding (AAC) is a proprietary audio coding standard for lossy digital audio compression.
In mathematics and computer science, an algorithm is an unambiguous specification of how to solve a class of problems.
Apple Lossless, also known as Apple Lossless Audio Codec (ALAC), or Apple Lossless Encoder (ALE), is an audio coding format, and its reference audio codec implementation, developed by Apple Inc. for lossless data compression of digital music.
In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
An audio codec is a codec (a device or computer program capable of encoding or decoding a digital data stream) that encodes or decodes audio.
An audio file format is a file format for storing digital audio data on a computer system.
A codec is a device or computer program for encoding or decoding a digital data stream or signal.
The following tables compare general and technical information for a variety of audio coding formats.
A content format is an encoded format for converting a specific type of data to displayable information.
A standard is a custom or convention that has achieved a dominant position by public acceptance or market forces (for example, by early entrance to the market).
Digital audio is audio, or simply sound, signal that has been recorded as or converted into digital form, where the sound wave of the audio signal is encoded as numerical samples in continuous sequence, typically at CD audio quality which is 16 bit sample depth over 44.1 thousand samples per second.
A container or wrapper format is a metafile format whose specification describes how different elements of data and metadata coexist in a computer file.
Digital radio is the use of digital technology to transmit and/or receive across the radio spectrum.
Digital television (DTV) is the transmission of television signals, including the sound channel, using digital encoding, in contrast to the earlier television technology, analog television, in which the video and audio are carried by analog signals.
FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation.
ID3 is a metadata container most often used in conjunction with the MP3 audio file format.
LAME is a software encoder that converts audio to the MP3 file format.
The following is a list of compression formats and related codecs.
Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.
In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content.
Metadata is "data that provides information about other data".
MP3 (formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) is an audio coding format for digital audio.
MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images.
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors.
Psychoacoustics is the scientific study of sound perception and audiology.
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service.
A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of a group of affected adopters.
A technical standard is an established norm or requirement in regard to technical systems.
A video coding format (or sometimes video compression format) is a content representation format for storage or transmission of digital video content (such as in a data file or bitstream).
Vorbis is a free and open-source software project headed by the Xiph.Org Foundation.
