[Meeting Intelligence] iOS Native Audio Recorder & Whisper.cpp Integration

[ucguy4u]

Problem

Real-time microphone capture and on-device transcription are missing on iOS.

Scope

• Implement iOS Swift platform channel handler.
• Configure AVAudioSessionCategoryPlayAndRecord and background audio mode.
• Integrate whisper.cpp iOS library.
• Handle audio session interrupts and Bluetooth routing.

Acceptance Criteria

• Audio session handles phone call interrupts gracefully.
• Whisper transcribes audio chunks locally on device.

Estimate

12 hours

Required Before Implementation: Use Cases + Automation Flow

Before coding this ticket, add a deterministic implementation note or child task covering:

• Primary user journey: actor, preconditions, trigger, happy path, success state.
• Alternate/failure paths: offline, missing model, permission denied, runtime/tool failure, cancel/retry, background/foreground.
• Automation flow: Given/When/Then steps, fixtures, mocks/stubs, UI assertions, state/database assertions, notification/tool-trace/memory assertions where relevant.
• Hardening checks: privacy redaction, accessibility, timeout/performance bounds, cleanup/reset.
• Delegation prompt: Ask a QA/test agent to write the automation flow before implementation begins.
