To help reduce listening fatigue caused by the unnatural stereo image provided by headphones, Crossfeed processes the left and right channels of stereo audio signals with a filter that mimics the sound absorption characteristics of the human head. After running through this filter, it then mixes a delayed portion of the left and right channels with each other to simulate the delay that occurs when listening to audio signals through stereo speakers positioned approximately 60 degrees apart from each other. The effect is subtle.

The most current version is version 0.92, released on January 17, 2005. Final version.

Currently in the development stage, Aurator will soon replace Crossfeed. It's based on a more refined and flexible version of the Crossfeed 0.92 engine. Check back soon!
