After long hours mixing or doing sound design it's good to get out and breathe some fresh air. Why not bring some mics along and record the ambient sounds of nature? I also compare CEDAR, iZotope Voice Denoise and Dialog Isolate, and Acon Dialog Extract on a noisy dialog sample recorded next to a waterfall.

In this video I used my iPhone for video, a Zoom F6, Sennheiser G3, Rode NT4, and some small stuff like batteries and accessories. For mono FX I will also record a Sennheiser MKH60 and Shure SM57 (yes, really!).
