AM Encoding is the most popular technique for creating “Silent Subliminal” recordings, which advocates claim can bring about positive shifts in one’s mindset. The technique was largely based on the 1989 US Patent US5159703A by Oliver M. Lowery for a “Silent subliminal presentation system”.
This plugin is an audio frequency AM encoder / decoder for speech. As I’ve lost so many links on this forum, I’ve decided to host the plugin on my own blog. More information, and the plugin itself may be downloaded HERE.
