Audio jitter is the measurable variation in the timing of audio samples or frames relative to their expected positions. Parameters: frame-level timing deviation, sample-level timing deviation, and their statistical distribution (jitter variance, peak jitter). Persistence mechanism: measured and logged by digital audio equipment, audio analysis tools, and streaming protocols that monitor clock alignment.

Definition
Why it is in scope
A human-made concept mapping timing variation in digital audio transmission and playback, built to persist as documented measurement and compensation practice.

Relations from this entry
- audio-processingSERVES →
Audio-jitter is a measurement concept maintained for audio-processing practice: engineers monitor jitter to diagnose timing errors, design clocking and buffering strategies, and evaluate streaming quality. The concept is built for the sake of reliable audio processing; servant points to beneficiary per Law 8d.
- sample-clockDEPENDS_ON →
Remove-Y test: jitter is defined as measurable variation of sample/frame timing relative to their EXPECTED positions. Those expected positions (n·1/fs, the ideal grid) exist only because the sample clock stamps each sample position with a defined interval. Remove the sample clock — no periodic timing reference — and there is no sample position, no ideal grid, hence no expected position to deviate from: the construct loses its measuring reference and stops operating. The reverse does not hold: the clock needs no jitter; jitter is a property measured against the clock, not the clock against jitter. (The cluster's earlier target 'clock' carved a PUBLIC timekeeping device; this is the machine-internal grid the definition actually measures against.)

Audio-jitter measures timing variation in sample delivery/playback. Remove sampling (the discrete sample framework) and jitter as a measurable deviation from expected sample timing ceases to exist. Law 8b.
- signal-samplingDEPENDS_ON →
Audio-jitter's accepted body defines it as deviation of inter-sample intervals from the nominal clock period — its referent is a discrete sample stream. That stream is constituted by signal-sampling: the fixed rate and uniform time instants establish the nominal intervals from which jitter deviates. Removal test (Law 2b, object-level): remove signal-sampling and 'timing variation of audio samples' loses the object it describes — the referent vanishes, it is not merely unsayable. Pinned sense (Law 11d): dependency on the sampling practice that fixes the nominal inter-sample grid, not on the statistical-sense 'sampling' entry. (Seth's parallel edge targets statistical sampling — wrong entry; this is the correctly aimed claim.)
