    I've been working on hand-tuned DSPs for spatial audio for VR and I ended up inventing a really, really precise crossfeed. I've been studying the human head and ears for over 2 years now trying to figure out what makes a HRTF do what it does and replicate it from scratch. When I finished my hand-tuned DSP, I realized that if you remove the phase positioning system that does positioning based on the sound source in game, it can be applied as an effect on a standard stereo audio signal and makes a pretty unique crossfeed.

    It's also super, super subtle. A Hi-Fiers dream! Subtly simulating ITD and reducing strain without massively (or sometimes even audibly) mucking with the source file's audible phase or soundstage.

    Stereo imaging is not super affected but he opposite ear never feels "hollow".

    Audibly, there is barely a difference:

    It's just a little tiny bit less fatiguing on your brain. That's it. It doesn't affect the sound in any meaningful way other than making long listening easier--especially with old songs that have heavy pans like The Beatles. I should put up some Beatles examples.

    So... how do we apply this to our own music :D

    Super duper subtle, but really interesting none the less! I'd like to apply it to some tracks I'm more familiar with to determine if it's having any effect on freq resp, soundstage, etc.
