Compression artefact | definition and usage
https://videocide.com/glossary/compression-artefact/
Block boundary discontinuities can occur at edges of motion compensation prediction blocks. In motion-compensated video compression, the current picture is predicted by shifting blocks (macroblocks, partitions, or prediction units) of pixels from previously decoded frames. If two neighboring blocks use different motion vec…

Sources of Audio Artifacts Compression. Sometimes, in the process of gain reduction, compressors can likely cause audible artifacts. In such a situation this can alter the timbre of sound thereby creating something unwanted. In other situations it may be intentional and may be done to contribute to the overall meaning of the sound recording.
Mastering For Compressed Audio Formats: MP3 Artifacts …

These audio examples accompany a blog article that illustrates the best practices when mastering for delivery to various compressed audio formats. Though SoundCloud streams all audio at 128kbps MP3, the source files are available for download, so that the sound quality of the WAV and MP3 examples can be evaluated.
Compression Artifacts in Perceptual Audio Coding - IEEE ...
https://ieeexplore.ieee.org/document/4490000
Abstract: Perceptual audio coding achieves a high compression ratio by exploiting the perceptual irrelevance and data redundancies. By using advanced and sophisticated signal processing methods, perceptual coding has generated artifacts that are quite different from the traditional distortions.

Common Artifacts Of Lossy Compression. The following examples, for which I've created audio examples, demonstrate some of the most common and obvious artifacts of various perceptual audio encoding technologies. • Loss Of Bandwidth. Not all encoders are created equal, and even those of the same format do not perform identically at identical ...

Answer (1 of 3): There are two types of compression that affect the sound of a recording. One is the use of audio compression, which is an amplifier that will affect the gain of a signal in a complex way. A threshold is set, and any part of the signal …
Compression artifacts : audioengineering
https://www.reddit.com/r/audioengineering/comments/5j79vo/compression_artifacts/
The hydrogenaudio.org forums are a good place to begin. They test and tune compression codecs using ABX testing, and I believe they have descriptions and demonstrations of these types of artifacts. Quantization noise (or quantization distortion) is not specific to MP3/AAC compression, but part of digital audio in general.
So what are these audio "artifacts" anyway? | AVS Forum

The codec artifacts do not sound anything like level compression. K-EARTH in LA, for instance, has ghastly level compression on both their analog and HD - pumps like crazy - but the sound quality on their 96 kbps stream is still vastly superior, and has negligible codec artifacts that I can't even hear without headphones.
