drop grunting + dead synth module
Three lung sounds that were Web-Audio syntheses now play real clinical
recordings sourced from the HLS-CMDS manikin dataset (MIT license):
- normal-vesicular.ogg
- rhonchi.ogg
- pleural-rub.ogg
Dropped expiratory grunting from the library entirely — no
openly-licensed clinical recording located across Wikimedia, Freesound
CC0, SPRSound, Pixabay, Internet Archive, or Littmann/EasyAuscultation
(all proprietary). Card is honest by omission rather than hiding a
synth behind a Play-only UI.
All seven remaining entries now use the same native <audio controls>
player (pause, seek, volume). The synth fallback branch in
renderSoundCard, the stopAllExcept synth reset loop, the script tag,
and the entire public/js/respiratorySounds.js (332 lines of Web Audio)
are removed since nothing references them anymore.
Four changes rolled together:
1. REAL AUDIO from Wikimedia Commons (CC BY-SA 3.0, attribution to follow
in privacy policy per Daniel). Embedded in /public/audio/ — synthesis
stays as fallback for sounds not available from Wikimedia.
respiratorySounds.js now tries the real OGG first; falls back to Web
Audio synthesis if file missing.
2. REAL APTM IMAGE from Daniel's Nextcloud share, placed at
/public/images/pe-guide/aptm.png (134 KB PNG). Replaces the inline SVG.
Kept the side legend with A/P/E/T/M colour-coded points.
3. INNOCENT MURMUR REFERENCE PANEL below the APTM diagram with the 5
classic innocent murmurs (Still's, pulmonary flow, venous hum, carotid
bruit, PPS) — age, location, character, confirming maneuver — plus
the 7 "S" criteria summary.
4. ALL-AGE RESP + CV DATA. Before: only adolescent. Now every age group
has age-appropriate resp + cv content (newborn through adolescent).
Newborn: Silverman, pre/postductal sats, duct-dependent lesion screen.
Infant: bronchiolitis, CHF diaphoresis, VSD, early CHD.
Toddler: croup/FB/epiglottitis, innocent murmur peak age.
Preschool + school-age: adult-pattern transition, sports screening.
