ChirpHound

About ChirpHound

That periodic chirp is real. ChirpHound helps you work out which device and which room it is coming from.

Choose a frequency preset, start a hunt, and walk through the space. ChirpHound learns the local noise floor, isolates tonal energy in the selected band, and gives you a live warmer/colder signal as you approach the source.

FIELD TOOLS
• Live relative-dB warmth gauge and optional directional estimate
• Narrow-band detector with adaptive room calibration
• Scrolling spectrogram and dominant-frequency matching
• Room Finder for comparing readings across locations
• Live chirp log with timestamps, intervals, and burst grouping
• Sweep Plan that turns captured evidence into practical next steps
• Local hunt history, notes, CSV export, and PDF field reports
• Offline reference guide for common alarm and household beep patterns

SAFETY-FIRST PATTERN GUIDANCE
ChirpHound recognizes repeated groups as well as periodic single chirps. A three-beep alarm pattern is treated as possible smoke or fire. A four-beep alarm pattern is treated as possible carbon monoxide. Maintenance codes vary by manufacturer and model, so two- and five-chirp patterns prompt you to verify the exact device manual instead of making a universal claim.

PRO AUDIO DIAGNOSTICS
See detector calibration, active microphone route, sample rate, channel count, tonality, and relative signal level while you work. Audio interruptions and unavailable routes are handled with visible recovery guidance.

BUILT FOR PRIVACY
• Audio is analyzed live on this device.
• Audio is not recorded or uploaded.
• No account is required.
• No advertising, analytics, tracking, or third-party SDKs.
• Hunt data remains in the app container unless you explicitly export it.

ChirpHound is a locating and reference aid. It is not a smoke alarm, carbon-monoxide alarm, calibrated sound-level meter, or substitute for emergency action. If an alarm is sounding, follow its instructions and contact emergency services from a safe location.
