* **ntfy**: server (default `https://ntfy.sh`), **topic** (pick something unguessable: anyone who knows it can read it),
optional heartbeat topic and interval (hours, 0 = off). Subscribe to the topic in the ntfy phone app.
* **Hardware**: pins, I2S slot, `Right shift` (default 14 = 4x digital gain for the quiet INMP441).
* **Detector defaults**: threshold, loudness gate, N/M, cooldown (default 5 ms). The existing N-of-M sliding window smooths frame matches; because frames arrive every 32 ms, cooldown/re-arm timing is effectively frame-granular. All can also be changed live with `set` and persist in NVS.
* **Detector defaults**: threshold, loudness gate, N/M, and a 500 ms quiet tail for grouping intermittent matching frames into one buzz. Each new match within that tail extends the event; its reported duration runs from the first qualifying match through the last, excluding the final quiet tail. Duration is frame-granular (32 ms hops), and is included in the alert notification and `status`. Settings can also be changed live with `set` and persist in NVS.
* Console: defaults to the **UART** USB port. For the native USB port set *Component config > ESP System Settings > Channel for console output*
to *USB Serial/JTAG*.
