I generally try to be unbiased in answering this question, but I think that it is mainly matters if you believe in subliminal messages or not.ġ. I cannot promise that the “Subliminal” plugin (or any other subliminal message machine) produces any useful result. I only translated the electrical description in Lowry’s patent paper into Nyquist code. The “RFT” in edgar-rft is the german abbreviation for audio/video recoding equipment electrician. I have been listening to the silent subliminal messages for two weeks now. Original under Silent Subliminals with Audacity - text is in German but nothing you do not already know… The maximum modulation depth is at a carrier frequency of “track-sample-frequency / 2 / sqare-root-of-two”: (princ 'The track sample frequency must be minimum 44100Hz.') (let ((result (mult 2 (cut #'lowpass8 (hp sound 80) cutoff) (setf sound (funcall function sound frequency)))) otherwise the modulated carrier aliases. the difference between the carrier and *sound-srate*/2, because It must not be greater than carrier/2, but also not greater than

The CUTOFF is the maximum allowed frequency in the modulator. We have two Nyquist frequencies, carrier/2 and *sound-srate*/2. I cannot find any aliasing or mirror frequencies with the Audacity “Analyse > Frequency Analysis” and everything looks pretty well. It works with a cheap 44.1kHz standard soundcard. I think I have a finally working Silent Subliminal plugin producing an SSB modulated carrier like the original Lowerey machine.
