Bigfoot researchers, Corey and Tye, have been getting a lot of recordings of possible howls. The following audio is one of the best ones so far. It was recorded in April 2016. I have attempted to do some enhancement work on the Audio. The only issue with the recording was the dreaded wind noise. So, to combat some of this I focused on the howls with the least amount of wind noise.
The howls went on for well over 2 minutes.

Here is my attempt at enhancing the audio.
