Definition

Audio-clock-drift is a human-made measurement concept that maps the systematic deviation between the nominal rate of a digital audio clock and a reference time base. It is parameterized by drift rate in parts-per-million, by direction (fast/slow), and by accumulation over operating intervals, and persists through standards documents, test procedures, and compensation algorithms in audio engineering practice and software implementations. [formal: driftus horologicus | substrate: matter | horizon: hours | explicit: yes | epoch: 0.02]

Why it is in scope

A human-made concept mapping timing deviation between digital audio clocks and reference time, built to persist as documented measurement and compensation practice.

Names and aliases

Relations from this entry

  • audio-processingSERVES →

    Audio-clock-drift is a measurement concept maintained for audio-processing practice: engineers monitor drift to keep sample rates aligned across devices, compensate in playback/recording chains, and design clocking hardware. The concept is built for the sake of reliable audio processing; servant points to beneficiary per Law 8d.

  • sample-clockDEPENDS_ON →

    Audio-clock-drift measures the deviation of the sample-clock from its nominal rate. The drift concept operates against the sample-clock's timing reference: without the periodic grid that marks every sample position, there is no expected timing to deviate from. Remove the sample-clock and the concept of clock drift loses its measuring reference entirely — the removal test passes per Law 8b.

  • cmr784rhz003os1262yaiijpeDEPENDS_ON →

    Audio clock drift measures the deviation of audio device clocks from true time. It needs clocks to operate — removing the clock concept eliminates the very standard against which drift is measured. Clock (epoch 0.64) is far more foundational than audio-clock-drift (0.02).

  • cmrw0g7st02xt2ceiy2ihtwthDEPENDS_ON →

    audio-clock-drift is the phenomenon where a sampling clock varies from its nominal rate — it fundamentally depends on the sampling process to exist as a concept. Remove sampling and there is no clock to drift, no sampling instants to misalign. The drift is a property of the sampling mechanism's timing.
