PROBLEM TO BE SOLVED: To provide a multipath evaluation device capable of completing a multipath evaluation process in a short period of time.SOLUTION: A multipath evaluation device, for evaluating a multipath noise included in an audio signal, includes: a section identification part for identifying a multipath section having signal intensity indicating multipath occurrence, and a background level section having signal intensity indicating signal strength considered as a background level, on the basis of the signal intensity of each section within an evaluation target period for the audio signal; and a calculation part for acquiring a multipath evaluation value by calculating a signal to noise ratio for signal intensity at the multipath section using signal intensity at the background level section immediately before the multipath section. |
