Sound is that of a crescendo-decrescendo ejection murmur. The 6th beat in the sample is a ventricular premature beat (VPB). The 7th beat illustrates post-VPB potentiation of the murmur due to increased left ventricular filling during the post-VPB compensatory pause, which causes increased turbulent flow past the stenotic valve during the next ventricular contraction.
