Hi guys, I dont know that much about audio , I am more a video guy. I am making a video for a friend in costa rica and I hired a costa rican sound guy to make the audio..... It is terrible.

He recorded the levels VERY low and there are some sort of cicada's or locusts making a high pitch hiss in the background. I am now back in the states and looking for any way I can salvage this audio to be used for an online only video. Keep in mind I work in final cut and only have the audio filters that come stock (apple & fcp)

here is a sample audio clip so you guys can here it, what filters should i use?
