When the host attaches to an already-running game it never saw the stream's Initialize, so the render-hook assumes the device mix format and measures only the sample rate from the render cadence -- which a jittery game can make wrong (intermittent pitch shift). But during the measurement window the game is still audible, so we have the same audio twice: the hook (pre-mix, unknown format) and a process-loopback (post-mix, the known device format). Cross-correlating them pins the true rate from ground truth. - common/include/coop/audio_correlate.hpp: the pure correlator. Resample the hook by each candidate standard rate up to the device rate and score how well it aligns with the loopback across the window (drift-detecting). audio_correlation_test recovers every rate (score ~1.0 vs ~0.01 for wrong ones), incl. 44100-vs-48000, and rejects unrelated signals. - Hook measurement tap: a host-set verify_capture ring flag makes the hook push a still-being-measured (guessed) stream's raw pre-mix bytes WITHOUT silencing, so the host can co-capture both signals (a silenced game's loopback is silent). Inert by default -- the shipping no-echo path is untouched. - host/src/audio/audio_format_verifier: co-captures hook + loopback and correlates, feeding a correction into the existing override channel. Wired into AudioMirror's measurement window (hidden in the gap loopback already covers, so exact streams pay nothing). audio_verify_test drives it end-to-end against coop_mock_game. Rate vs layout are coupled (correlating the waveform needs the right channel de-interleaving), so this step assumes the hook layout matches the device (the common stereo-on-stereo case); recovering a different channel count / bit depth is step b.
