 | Julesomega SUBS Member since Nov 2015 102 Points Moderator | Nothing is muted on records, but with CDs the noise floor is so much lower than vinyl media, where the noise is dominated by surface imperfections and damage. It is lowest on digitally recorded CDs, the alternative being CDs of older material recorded on tape, or even dubbed from vinyl. Digital noise manifests at medium sound levels, appearing as 'artefacts' related to the wanted sounds. |

 | Gill Sans SUBS Member since Apr 2014 1117 Points Moderator | No! Records, tapes, CDs are never made with muting applied. Muting is unknown in the world of audio. It is de rigeur in the world of CB and private radio. Not sure where you get this idea of 'muting'. Edited by Gill Sans on 15th Dec 2024, 11:55 AM |

| scrough No picture 'cos I'm not into 45rpm :( Member since Jan 2013 3444 Points Moderator | Any digital signal is limited in accuracy depending on the bit depth. CDs have a 16 bit range, and 'noise floor' refers to to the accuracy obtained in the signal. See the begining of https://en.wikipedia.org/wiki/Audio_bit_depth. |

| Julesomega SUBS Member since Nov 2015 102 Points Moderator | The noise floor can be reduced by oversampling, which was fashionable on up-market CD players for a while. |
