I was wondering if anyone out there who has ever worked with holographic subliminal messages in audio, or hemi-sync (where slightly different frequency tones are played in each ear through headphones) have experimented with, or at least read of a study done to see if lossy audio encoding has a destructive effect on these technologies.

I'm concerned that subliminal audio and hemi-sync might partly be based on sounds that the human brain doesn't readily perceive, and thus the encoding process might "throw away" sound that is required for subliminal audio to be effective.

I'm especially concerned about whether joint stereo will wreck the effect of these techniques, since they are based on stereo separation of sound. Would it? Should I force encoding to actual stereo, or is Joint Stereo okay for this stuff?

I try to use lossless for this stuff wherever possible, but obviously that's not always practical.

Any informed responses much appreciated!

Why cant LAME just rename joint-stereo to "smart stereo" and the current "stereo" to "dumb stereo" so that these kinds of misunderstandings finally stop? :)
