Music:
I've only just found out about this, but i started work on a song last night.

Binaural (3D) SFX:
Haven't made anything to post yet, but it will be coming.
Binaural sounds are recorded with microphones that act as ears. This technique allows the sound to sound as if it's coming from the right or the left, or even in front or behind you. Without the use of panning the sound left or right. Note: This effect really only works well with headphones. It can work with speakers, but not nearly as well.
Here is an example:

This would of course require the consent of the person that originally made the samples, and the credit is still theirs, but it's something i can do.
