6SNT.ACD

Audio Chain Doctor is a compact desktop preflight tool for Windows radio stations.

It checks whether the local audio chain looks usable before operating: input level, peak level, clipping risk, noise floor, latency, endpoint routing, waveform and VU behavior.

What It Does

• Reads the selected Windows audio input in a local read-only meter.
• Shows VU, RMS level, peak level, clipping state and waveform.
• Lists and selects detected input/output endpoints inside the app.
• Supports EN/ES from the top bar.
• Saves a local diagnostic/profile report.
• Sends a short local 1 kHz tone only after explicit operator confirmation.

What It Does Not Do

• It is not a logbook.
• It is not a cloud service.
• It does not key PTT or control a transceiver.
• It does not change Windows default devices, volume or routing.
• It does not promise future versions or support windows.

Safety Model

Metering and device discovery are read-only. The only output action is the local tone test: it is short, visible and requires confirmation before playback.

The app is distributed AS IS. Use it as an operator aid, not as a guarantee that the complete radio chain is safe or correctly configured.

Run Locally

.\scripts\run_app.ps1

Deterministic demo mode:

.\scripts\run_app.ps1 --sample

Build Windows EXE

.\scripts\build_exe.ps1

Output:

dist\6SNT.ACD.exe

Build artifacts are intentionally ignored by Git.

Troubleshooting

• No level movement: verify the selected input endpoint is the one receiving audio.
• Wrong device shown: use the selector button beside INPUT or OUTPUT.
• Tone not audible: select the expected output endpoint and confirm Windows is not muted.
• Audio review state at -90 dB: the selected input is silent or not receiving the signal.
• USB Audio CODEC appears multiple times: Windows/PortAudio can expose the same hardware through multiple host APIs.

6SNT.ACD revisa la cadena de audio local antes de operar. Mide entrada, nivel, picos, clipping, ruido, latencia y forma de onda. Permite seleccionar dispositivos, cambiar EN/ES y emitir un tono local breve con confirmación.

No controla el radio, no hace PTT y no cambia la configuración de audio de Windows.
