How do I get the audio of an in-engine cinematic out as a file in Godot and Unreal, and what format and sample rate will it be?

Godot Movie Maker records audio non-real-time at a 48 kHz default; the PNG writer writes a stereo WAV whose header declares format code 1 (integer PCM) at 32 bits per sample, while OGV/AVI embed audio. Unreal MRQ WAV parameters are not stated in the pages the producer read. Curator qualifications: Docs/code read 2026-10-22; no engine run; drift figures are arithmetic. Unreal MRQ/legacy render pages (S34-S38) from producer reading. 32-bit integer PCM WAVs are not accepted by every editor; check the target tool (curator note, not from sources). Limitations: Docs/code read 2026-10-22; no engine run; drift figures are arithmetic. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
