In a scheduled meeting the WebView owns the mic (the plugin has no LiveKit room), so
the native-call AudioRenderer tap didn't apply. Now the WebView reads its OWN local
mic PCM via Web Audio (the same non-intrusive tap the app already uses for
active-speaker metering — NOT a 2nd getUserMedia, which would fight the call's mic on
iOS and yield silence), downsamples to 16 kHz mono Int16, and forwards it to the
plugin's SFSpeechRecognizer via feedAudio(). Native calls keep the LiveKit tap.
Muted -> the local track carries silence -> nothing transcribed; the feed re-inits
when the mic goes live on unmute.
- Plugin: startTranscription({external:true}) runs the recognizer without a track;
feedAudio({pcm,rate}) decodes base64 LE Int16 -> Float32 buffer -> recognizer.
- Web: startSR now uses the native recognizer for ALL iOS meetings (native call =
LiveKit tap, scheduled = PCM feed); desktop/browser unchanged (Web Speech API).
Web deploys now; the plugin's feedAudio/startExternal ride the next Codemagic build.
