m3resp.compute_offsets_from_timestamps

m3resp.compute_offsets_from_timestamps(reference_modality, timestamps)

Convert absolute per-device start timestamps into manual offsets (plan_stage2.md Sec 20, “timestamp alignment”).

Each modality’s events are relative to that modality’s own recording start. If a modality’s device started recording timestamps[modality] seconds after reference_modality’s device did, its events must be shifted forward by that same amount to land on the reference timeline. Feed the result straight into align_events_by_modality_offset.

Parameters:

• reference_modality (str)

• timestamps (Mapping[str, float])

Return type:

dict[str, float]
