# Audio capture shim for Triple-C voice mode.
# Claude Code spawns `rec` or `arecord` to capture mic audio.
# Inside Docker there is no mic, so this shim reads PCM data from a
# FIFO that the Tauri host app writes to, and outputs it on stdout.

FIFO=/tmp/triple-c-audio-input

# Create the FIFO if it doesn't already exist
[ -p "$FIFO" ] || mkfifo "$FIFO" 2>/dev/null

# Clean exit on SIGTERM (Claude Code sends this when recording stops)
trap 'exit 0' TERM INT

# Stream PCM from the FIFO to stdout until we get a signal or EOF
cat "$FIFO"
feat: add voice mode support via mic passthrough to container Enables Claude Code's /voice command inside Docker containers by capturing microphone audio in the Tauri webview and streaming it into the container via a FIFO pipe. Container: fake rec/arecord shims read PCM from a FIFO instead of a real mic. Audio bridge exec writes PCM from Tauri into the FIFO. Frontend: getUserMedia() + AudioWorklet captures 16kHz mono PCM and streams it to the container via invoke("send_audio_data"). UI: "Mic Off/On" toggle button in the terminal view.
