Blackmagic's support-listing notes mention three Voice Isolation fixes, all in Studio builds: short audio clips (18.1.1, 23 Nov 2022), playback on energy-efficient CPU/GPU systems (18.5.1, 14 Aug 2023) and audio sync when bouncing (18.6.3, 14 Nov 2023). The notes say 'improves' and do not describe the earlier behaviour or give thresholds, so what exactly went wrong in earlier builds is unknown. No later (19, 20, 21) update note in the listing mentions voice isolation.

Curator qualifications: Three version-labelled vendor fixes verified; reading 'improves' as a prior defect is inference, as the producer says.

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