01 — Device to Diagnose
02 — Symptom
Optional — hold still and quiet for 2 seconds before recording in a noisy space (running engine bay, road noise). Measures the constant background and subtracts it from what you record next, so the fingerprint reflects the actual fault, not the environment.

05 — Find Reference Sounds
Searches Freesound's CC0 (public domain) library for the currently selected patient category. Get a free API key at freesound.org/apiv2/apply. This is the one part of AUSCULTA that talks to an external server — your search text and key go to freesound.org.
06 — Search YouTube for Reference Sounds
Get a free API key from the Google Cloud Console (enable "YouTube Data API v3"). Important: this can't pull audio directly out of a YouTube video — that's against YouTube's terms of service, and there's no reliable way to do it across browsers even if it weren't. What this does instead: finds videos matching your search, so you can open one, play it near your microphone, and hit Record Live above — same as capturing any real-world sound.

No examples saved yet — diagnose, teach, upload, or search to start building your library.
Frequency Monitor
A standalone mic/setup test — works on its own, no matching or diagnosis involved. Run this to confirm your mic is clean before recording a symptom, or just to see what your recording environment looks like.
This tool can't run without mic access. Check your browser's site permissions and allow the microphone, then press Run again.
Real-Time Spectrum Analyzer
Click anywhere on the graph to pin a frequency and track its level continuously. Click again to release it.
No events yet — spikes, clipping, feedback, or elevated noise will be logged here with a timestamp as they happen.
Mic Test
Checks the microphone itself, separate from analyzing any particular sound — is it detected, does it sound clean, how noisy is it at rest, how much headroom before it clips.
This tool can't run without mic access. Check your browser's site permissions and allow the microphone, then press Start again.
Hear Yourself
Not run yetRecords 3 seconds, then plays it straight back — the fastest way to catch hiss, distortion, or a muffled/thin mic before you rely on it for a diagnosis.
Noise Floor
Not run yetStay quiet for 3 seconds — this measures how much self-noise and room noise the mic picks up with nothing happening.
Headroom
Not run yetMake the loudest sound you expect to record — clap, tap the mic, whatever's realistic — for 3 seconds. Checks how close to clipping it gets.
08 — Backup Your Library
Your whole library lives in this browser — download a backup regularly, especially before clearing browser data or switching devices.
