Hi

I've used audacity for some time now, I've also been purchasing/using subliminal messages for a while, however, my suspicion has been raised by the fact that the silent version of the subliminal tracks show no waveform in Audacity. I understand this could be due to the frequency they have been recorded at and that this may not display in Audacity - therefore appears as a flat line. The audible versions contain wave soundscapes as a background - or maybe that's all they are and there is no subliminal behind it? In which case, I've been ripped off.

I've also tried the above Nyquist function and there is no difference - the waveform is still a flat line.

This company may be legit and using advanced processing or just relying on the placebo effect caused by the power of suggestion coupled with the use of relaxing soundscapes. They do include a copy of the script they claim is encoded into each subliminal program - but that does not guarantee anything, other than potentially re-enforcing the scam.

I will contact them now to ask exactly what processes they are using to encode the message and what frequency they are recording at

Audacity's spectrogram display would show any frequencies present , even at a very low "subliminal" level.
