REAPER's version history documents preserving the source start offset on render (v7.16, adjusted for take offset), a batch-converter choice between keeping the BWF start or using item position (v5.985), clearing offset data on consolidate/glue with source metadata (v7.35), and adjusting the written position after trimming silence (v7.37). No entry or API text says how a stored sample-count start is rescaled when the sample rate changes (no pull-up/pulldown terms). Pro Tools and Resolve remain unresolved here.

Curator qualifications: Docs read 2026-10-22; no file imported, rendered or converted. Sample-rate-conversion behaviour unknown (would need a fixture test).

Limitations: Docs read 2026-10-22; no file imported, rendered or converted.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
