摘要：
The present invention refers to a signal processing apparatus and its method of operation. The apparatus comprises a phonocardiogram interface adapted to receive a phonocardiogram signal captured according to a first set of capturing properties, a processor adapted to analyze the phonocardiogram signal to determine an analysis result for the phonocardiogram signal and a confidence value of the determined analysis result, and a flow control adapted to determine, whether a subsequent capture of the phonocardiogram signal according to a second set of capturing properties is likely to improve an accuracy of the determined analysis result. If applicable the flow control coordinates the subsequent capture of the phonocardiogram signal according to the second set of capturing properties The invention also refers to a corresponding computer program product. Also described is a signal processing apparatus comprising a user interface adapted to present the captured phonocardiogram signal to a user and to receive a user correction. Based on the user correction the phonocardiogram signal may be reanalyzed.
