A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...
Blocking – low bitrate artifacts; Ringing – low and medium bitrates artifact, especially on animated cartoons; Blocks (slices) damage in case of losses in digital transmission channel or disk injury (scratches on DVD) Different suppression methods are used to remove all these artifacts from video.
When sampling is performed without removing this part of the signal, it causes undesirable artifacts such as black-and-white noise. In signal acquisition and audio, anti-aliasing is often done using an analog anti-aliasing filter to remove the out-of-band component of the input signal prior to sampling with an analog-to-digital converter.
Often audio engineers and sound editors use DAWs to manually remove "pops and ticks" from recordings, and the latest spectrographic 'retouching' techniques allow for the suppression or removal of discrete unwanted sounds. DAWs are capable of removing the smallest of anomalies, often without leaving artifacts and other evidence of their removal.
The compression ratio (that is, the size of the compressed file compared to that of the uncompressed file) of lossy video codecs is nearly always far superior to that of the audio and still-image equivalents. Video can be compressed immensely (e.g., 100:1) with little visible quality loss

Aliasing is a major concern in the analog-to-digital conversion of video and audio signals. In the creation of computer music and electronic music in the past decade, particularly in glitch music, software is used to create sonic artifacts of all stripes.
