Could anyone remove this from the audio?

Toyed around in FL Studio with the midi keyboard. Apparently I had used the wrong type of audio recording, since the melody was completely fine until I listened to the playback of what had been recorded; it sounds like an echo, a sort of white noise that layers the entire song and makes it hard to listen to.
The audio file is here: https://drive.google.com/open?id=0B00fbFb1XcMENUtEbXMwdXMxclU
I've attempted almost all the options in FL but none remove or even alter the high pitched squeaks that are coming from the audio, so is there any way to salvage the original melody? I'd appreciate it.
