  2. Compression artifact - Wikipedia

    en.wikipedia.org/wiki/Compression_artifact

    Compression artifacts in compressed audio typically show up as ringing, pre-echo, "birdie artifacts", drop-outs, rattling, warbling, metallic ringing, an underwater feeling, hissing, or "graininess". An example of compression artifacts in audio is applause in a relatively highly compressed audio file (e.g. 96 kbit/sec MP3).

  3. Sonic artifact - Wikipedia

    en.wikipedia.org/wiki/Sonic_artifact

    A good example of the deliberate creation of sonic artifacts is the addition of grainy pops and clicks to a recent recording in order to make it sound like a vintage vinyl record. Flanging and distortion were originally regarded as sonic artifacts; as time passed they became a valued part of pop music production methods.

  4. Record restoration - Wikipedia

    en.wikipedia.org/wiki/Record_restoration

    Record restoration, a particular kind of audio restoration, is the process of converting the analog signal stored on gramophone records (either 78 rpm shellac, or 45 and 33⅓ rpm vinyl) into digital audio files that can then be edited with computer software and eventually stored on a hard-drive, recorded to digital tape, or burned to a CD or DVD.

  5. Audio restoration - Wikipedia

    en.wikipedia.org/wiki/Audio_restoration

    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.

  6. Spatial anti-aliasing - Wikipedia

    en.wikipedia.org/wiki/Spatial_anti-aliasing

    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.

  7. Transparency (data compression) - Wikipedia

    en.wikipedia.org/wiki/Transparency_(data...

    Transparency, like sound or video quality, is subjective. It depends most on the listener's familiarity with digital artifacts, their awareness that artifacts may in fact be present, and to a lesser extent, the compression method, bit rate used, input characteristics, and the listening/viewing conditions and equipment. Despite this, sometimes ...

  8. Gapless playback - Wikipedia

    en.wikipedia.org/wiki/Gapless_playback

    Gapless playback is the uninterrupted playback of consecutive audio tracks, such that relative time distances in the original audio source are preserved over track boundaries on playback. For this to be useful, other artifacts (than timing-related ones) at track boundaries should not be severed either.

  9. Video denoising - Wikipedia

    en.wikipedia.org/wiki/Video_denoising

    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.
