If it's outside, perhaps it is a cicada?
I thought it might be an odd sort of cicada, or one making a different
sound, but I found a lot of cicada sound samples on the net and none
like this.
More data: This insect appears (or starts making its sound) in early
August and generally continues through September here in Pittsburgh. It
seems to only make its sound around dusk - from just after sunset until
around 9:30-10:00.
It really sounds like a couple of isolated "dogday" cicadas. Not to be
confused with the periodical 17-year/13-year cicadas. The dogday cicadas
have been chirping up a storm in my neighborhood this year. We get dozens
of them in chorus which is much louder and you can't really pick out
individuals.
This is a sound of a different type of cicada that sounds like yours:
