Telling one murmur from another is hard — for students, residents, nurses, advanced practice nurses and experienced physicians alike. Most heart-sound libraries let you listen to a recording again and again, but you can't take the sound apart. Auscultation Lab lets you slow a heartbeat down without changing its pitch, silence S1, S2 or the murmur one at a time, play only the moment around S1 or S2, and compare two sounds on the same time axis until the difference becomes obvious.

Every sound in the library is synthesized in your browser from published timing, frequency and envelope characteristics of heart sounds and murmurs. Building each layer separately is what allows slowing down, isolating layers and simulating bedside maneuvers. These are teaching models; confirm what you learn on real patients and real recordings.
The Chest tab lets you move a virtual stethoscope across the chest and hear each sound grow louder or softer along its radiation path. The Spectrum tab morphs a lesion from mild to severe, or mixes two lesions, with a schematic echo and Doppler view kept in step with the sound. In the Sculpt tab you draw the murmur a case describes and compare your version with the answer. The echo views are teaching schematics, not real ultrasound.
The Recordings tab separates recordings you load into S1, S2, murmur and noise tracks using automated signal processing, and measures murmur timing and shape. Those measurements can be wrong and are for learning only.
