The audio from our PAX East panel was a little overcooked (in addition to being muffled by masks).
Here’s a lil’ look at the effects pipeline to clean that up.
The only missing step is a destructive process prior to the rack to “unclip” distorted parts of the audio.
After processing, you can see a bunch of new “stuff” has appeared where it was black before.
I used an exciter to essentially create synthetic harmonics at the upper end, replacing what was “lost” at record-time.
Higher frequencies tend to have more noise anyway, so the synthetic harmonics derived from the lower frequencies is actually “close enough” for the human ear and brain.
