A method to classify heart murmurs as benign or pathologic. A digitized acoustic heart signature of a patient is captured on a computing device and processed using Fast Fourier Transformation to identify a plurality of component frequency waveforms, each having a power value. Based on the waveforms' power values, they are classified into a primary frequency waveform, harmonic frequency waveforms, and non-harmonic frequency waveforms. The heart murmur of the patient is classified using a ratio of the power values of the harmonic waveforms as a portion of the composite power value of all the waveforms, and an interface indication is provided to the user of the computing device. A computing device and software program per the invention are also disclose.
