Shannon's Journal Discussion

[Shannon]

As for mono speakers, both masked and ultrasonic formats use the same base audio, so they both suffer the same degradation through a mono speaker. I wouldn't use either one if it's possible, but it is equally damaged if you do.

Here is a question. An iPhone has only one speaker which means it's mono. But I noticed the iPhone mixes both channels of a stereo file into that one speaker. I also tested it with a self created short stereo file. I could definitely hear both channels. So would it be sufficient to use an iPhone in this case?

Mixing a left and right channel into a single channel is mono. One channel results. Left and right no longer exist. When both channels have very similar data it would be sufficient. But in this case, I use each channel as an exclusive transport for information, such that when the brain is presented with both channels, it is forced to use both hemispheres to make sense of the information. That results in a much more powerful subliminal, at the expense of having to use two channels. As a safety and backup, the information is eventually repeated in both channels such that even with a mono speaker it will work, but that is why it only gives about 45% of the full possible effect when you use mono instead of stereo.
