What is the interval type of the diapason? Closed or open at each side?
Related to the above: there should be an edge case where the result is of the form
(x, x), and depending on the answer above, either this orNoneshould be returned. (Also half-frequencies on both sides should be tested for this edge case.)thx for advice, fixed
It is not mentioned that the returned frequency range should also be integers, only the inputs.

Actual and expected are swapped in random tests
Wrong results in random tests, .eg.:
Expected result:
(1601, 4000), but1601-1467 = 134,1736-1601 = 135-> 1736 is not closer.fixed this problem by float numbers (now 1601.5 - 1467 = 134.5, 1736 - 1601.5 = 134.5 -> equal, in this way closer or further have no sense)
for what its worth, the
triangleis a poor choice of instrument for your description because it has no definite pitch...thx for advice, fixed
Noneall the timesolve a problem with random tests, thx
But what can I do with first issue?
I think it would be good to have a worked example. I tried reasoning out the problem but I still can't figure out how the closer/further info affects the range. I do not even know what a "diapason" is.
