Codecs are generally advised to accent assertive aspects of the media, or their use, to be encoded. For example, a agenda video (using a DV codec) of a sports accident needs to encode motion able-bodied but not necessarily exact colors, while a video of an art display needs to accomplish able-bodied encoding blush and apparent texture.
Audio codecs for corpuscle phones charge to accept actual low cessation amid antecedent encoding and playback; while audio codecs for recording or advertisement can use high-latency audio compression techniques to accomplish college allegiance at a lower bit-rate.
There are bags of audio and video codecs alignment in amount from chargeless to hundreds of dollars or more. This array of codecs can actualize affinity and obsolescence issues. The appulse is lessened for earlier formats, for which chargeless or nearly-free codecs accept existed for a continued time. The earlier formats are generally ill-fitted to avant-garde applications, however, such as playback in baby carriageable devices. For example, raw uncompressed PCM audio (44.1 kHz, 16 bit stereo, as represented on an audio CD or in a .wav or .aiff file) has continued been a accepted beyond assorted platforms, but its manual over networks is apathetic and big-ticket compared with added avant-garde aeroembolism formats, such as MP3.
Many multimedia abstracts streams accommodate both audio and video, and generally some metadata that admittance synchronization of audio and video. Each of these three streams may be handled by altered programs, processes, or hardware; but for the multimedia abstracts streams to be advantageous in stored or transmitted form, they have to be encapsulated calm in a alembic format.
