Comparison of video codecs. Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality ...
Audio codecs. FLAC – Lossless codec developed by Xiph.Org Foundation. LAME – Lossy compression (MP3 format). TooLAME / TwoLAME – Lossy compression (MP2 format). Musepack – Lossy compression; based on MP2 format, with many improvements. Speex – Low bitrate compression, primarily voice; developed by Xiph.Org Foundation.
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding ...
Multimedia. Multimedia is a form of communication that uses a combination of different content forms, such as writing, audio, images, animations, or video, into a single interactive presentation, in contrast to traditional mass media, such as printed material or audio recordings, which feature little to no interaction between users.
Some containers only support a restricted set of audio formats: DMF only supports MP3, AC-3, DTS and LPCM. EVO only supports MP3, AC-3, E-AC-3, DTS, MP2, MP1, DTS-HD, Dolby TrueHD, MLP and LPCM. F4V only supports AAC [g] and MP3. FLV only supports AAC, MP3, LPCM, A-law PCM, μ-law PCM, Speex, Asao and SWF ADPCM.
An audio coding format [1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus. A specific software or hardware implementation ...
An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is ...
