Rain Sound for Masked Subliminal

[Shannon]

Hi Shannon,
Could you please explain why we couldn't simply blend your "ultrasonic" silent track with a recording of rain?

In thread-2290 you say

You're welcome to do spectral analysis on my mp3's and see for yourself that the audio on the ultrasonics exists in a band between about 14.5 and 20 to 23 kHz.

and

it assumes that all subliminal audio is ultrasonic (pitch differenced), when masked subliminals are volume differenced instead.

From that I assume your masked subliminals are volume-differenced too (and indeed from a quick look at the spectrum in Audacity there doesn't appear to be anything above 19 kHz on your trickling stream masked subliminal of Absolute Self Confidence). Does that mean simple addition (of the silent + rain tracks) won't actually work? Even though playing each track separately (on 2 different audio devices) does work?

You are welcome to blend the ultrasonic track with a "cover sound" if you like. But, in doing so, you need to be mindful of two things.

1. You must not alter the original audio of the ultrasonic.
2. You must set the volumes properly in tandem.

If you want to create a rain track with ultrasonics in it, it's easy to do. But saving your mixdown must be done in a lossless file format, such as .WAV, .AIFF or .FLAC or you will strip out or damage the subliminal audio.
