TemporalWeak signal
Micro-timing variation
The tiny deviations from a strict grid that characterise human performance.
A drummer pushing the backbeat by six milliseconds is expressive; a sequencer placing it exactly on the grid is not. Measuring this reliably from a mixed stereo file, without stems and without a known tempo map, is genuinely difficult, and claims about it should be treated with suspicion.
We list it here because it is frequently cited in popular explanations of AI music detection as though it were easy to measure. It is not, and this engine does not claim to measure it directly.
How this tool uses it
Not used as a standalone feature. Only its coarse consequences are visible, through transient density and segment agreement.
What else produces the same reading
- Quantised human productions have no micro-timing variation either.
- Tempo drift in live recordings complicates any grid-based measurement.
