If the function succeeds, the return value is a
floating-point similarity score indicating the extent to which the two
audio clips sound alike. This score ranges from 0.0 (least
similar) to 100.0 (most similar).
RemarksEach parameter identifies an array containing a signature that was obtained through a call of
Reversing the order of the parameters does not change the similarity score.
The two audio clips need not have been recorded with the same resolution or sample rate and need not have the same duration.
Generally, a similarity score of 70 or more indicates a good match, that is, the clips sound substantially alike. Comparing signatures derived from identical clips always yields a score of 100.0.
