Recorded on a Zoom H4n with the built-in mics (120º spread).
* Low pass filter (cut everything 800Hz and below) to get rid of some unwanted ambient human noise and some accidental knocks of the recorder.
* Hi pass filter (cut everything above 10kHz) to remove some recording noise.
* Played with some of the midrange to reduce some noise (in the gap of quiet between 2-3k)
