Tethertone 0.2.0 — formerly AudioBridge

AudioBridge is now Tethertone. Same app, same features, new name, and new identifiers on both platforms.

Tethertone installs as a new app on both devices, so:

1. Delete AudioBridge from Applications on the Mac and uninstall it from the phone.
2. Install Tethertone from the files below.
3. Press Start on the Mac, approve the permission once more, and scan the new QR code.

Highlights

• Two capture methods on the Mac: ScreenCaptureKit (nothing to install) or BlackHole via AVAudioEngine (Microphone permission only).
• USB and Wi-Fi at once — the phone races every route and keeps the fastest.
• Uncompressed 16-bit PCM, 10 ms packets, adjustable jitter buffer, and continuous glitch-free clock-drift correction.
• Background playback with a foreground service.
• Live diagnostics on both sides: RTT, buffer depth, underruns, packet loss, drift ppm.
