Move the Audio tab body into AudioTab: output-device picker (with the
canonicalize + list-refresh dance and the audio:device-changed / -reset
listener), Hi-Res toggle, embedded Equalizer, the normalization block
(off / replaygain / loudness with pre-analysis attenuation slider and
LoudnessLufsButtonGroup), Crossfade + Gapless mutual-exclusion toggles,
preserve-play-next-order, and Track Previews (locations + start ratio +
duration). The audio-devices state (audioDevices, osDefaultAudioDeviceId,
deviceSwitching, devicesLoading) and refreshAudioDevices useCallback move
into AudioTab; preAnalysisEffectiveDb useMemo moves with them.
Settings.tsx 2266 → 1761 LOC (−505). Drops 8 imports that only the audio
tab used (lucide Play/Waves; listen; effectiveLoudnessPreAnalysisAttenuationDb;
LoudnessLufsButtonGroup; Equalizer; audio-device label helpers; the
TRACK_PREVIEW_LOCATIONS / DEFAULT_LOUDNESS_PRE_ANALYSIS_ATTENUATION_DB
constants; TrackPreviewLocation type).
Pure code move — no behaviour change.
