Grant's insight + proven on real session audio: we capture self (mic) and others (system) as separate tracks, then throw the separation away by mixing to mono — so the backend has to re-guess who's who. Analysis of a real call showed the channels are cleanly separated (envelope corr 0.015, NO echo); Caitlyn's 'Go Bitcoin' was 11.8x louder in system than mic, yet the mono mix + noisy visual named it 'Grant'. ChannelSelfVAD marks self-speech as windows where the mic is active AND louder than system (mic > system x1.5). Benefits: (1) self is identified by CHANNEL, not by the on-screen name — set one name in Settings, no per-platform matching; (2) a remote speaker (or room echo) can never be mislabeled as self. Computed at finalize from the two finished WAVs; the live capture path is untouched. Falls back to mic-VAD if tracks can't be read. SessionController feeds these spans to the backend timeline. Validated on the real session: 16 self spans; 'Go Bitcoin' (72-74s) correctly EXCLUDED, Grant's 49.9-53.3s / 62.6-64s correctly INCLUDED. 33/33 XCTest (5 new).
Ten31 Transcripts
Native macOS menu-bar app that auto-detects conference calls, records local audio,
builds a visual-derived speaker timeline, and hands audio + timeline to the
SparkControl backend for naming/transcription. See docs/ for the full spec.
This repo is at Phase 0 (scaffold, permissions, backend health check).
One-time setup
- Install Xcode from the Mac App Store (free; ~40 GB). Open it once and accept the license prompt.
- Install XcodeGen (generates the Xcode project from
project.yml):brew install xcodegen - Generate the project:
This creates
xcodegen generateTen31Transcripts.xcodeproj(git-ignored — regenerate any time). - Open it:
open Ten31Transcripts.xcodeproj - Signing is preconfigured:
project.ymlsetsDEVELOPMENT_TEAMto the free personal teamBK4Y6CXN35with automatic signing, so Signing & Capabilities should already show the team — no manual selection needed. (If you ever sign with a different Apple ID, updateDEVELOPMENT_TEAMinproject.yml, not in Xcode —xcodegen generateoverwrites Xcode-side changes.) - Press Run (⌘R).
Note: after adding files in a new phase, re-run
xcodegen generateand let Xcode reload the project. The signing team persists because it lives inproject.yml, so macOS permissions stay granted across rebuilds.
What Phase 0 does
- Launches as a menu-bar-only app (no Dock icon).
- Menu panel shows live status for the three permissions it needs — Microphone, Screen Recording, Accessibility — with Grant / Open Settings buttons.
- Shows a backend health check (
GET /api/status) against the configured host. - Settings: backend base URL, skip-TLS toggle (on by default for the self-signed cert), output folder, and adapter toggles (inert this phase).
No audio capture, call detection, screen reading, or backend hand-off yet — those
arrive in Phases 1–6 (docs/04_BUILD_PLAN.md).

Notes
- App Sandbox is off and Hardened Runtime is off — this is a personal, LAN-only tool that must observe other apps. Revisit only if distributing.
