PROBLEM TO BE SOLVED: To provide a respiratory sound data processor which can acquire respiratory sound data wherein a flow rate and/or a flow velocity (or a respiratory time and/or a respiratory sound strength) are normalized without using a flowmeter, can support an effective diagnosis by analyzing the respiratory sound data, and is compact and has a simple constitution, and a program for analyzing the respiratory sound data by controlling the respiratory sound data processor. SOLUTION: The respiratory sound data for one respiration is acquired by a one-respiration sound extracting means 131, and the respiratory time and the respiratory sound strength are calculated from the acquired respiratory sound data for one respiration by a one-respiration sound normalizing means 132. The flow rate and/or the flow velocity for one respiration are calculated based on the respiration time and the respiratory sound strength, and whether the flow rate and/or the flow velocity are normalized or not is judged. By a subsidiary sound detecting means 133, the presence/absence or the like of subsidiary sounds contained in the respiration sound is detected based on the respiratory sound data of the normalized flow rate and/or the flow velocity.
