Equalization can be of benefit in the post-processing of most field recordings. Here are some of my commonly-used equalization schemes and reasoning. I will update this periodically as I make changes to my workflow or learn new methods.
I like recording ambient sounds of nature, locations, equipment, and other assorted noises. When I play my recordings back, I want them to sound exactly like when I was there. Here is my technique, equipment, and settings I use.
Dolby HX Pro Headroom Expansion was a method used in tape recordings in the 80’s to give an improved signal-to-noise ratio. As a result, the recordings were much more powerful-sounding with clarity and presence as well as low-end strength. It did this by introducing a bias signal at the high frequency to push the recording out of the inherent non-linearities of tape.
I had one of the tape decks that could record in HX Pro and it made every recording just shine. I wanted to achieve this with today’s vst plugins and I believe I finally have with the U-he Satin tape simulating plugin.
