Embedded Subluminals

I have two questions dealing with Subliminals that I couldn’t find on this forum.
Recently, I bought 4 Subliminals from 2 different websites.
2 are .wav files
2 are mp3’s.
1st question. If I merge the two .wav files into one in Audacity, and export it to my laptop (Windows 10) and then download it to my phone, will the embedded recordings (Subliminals) and the binaural beats still be present?
2nd question. If I merge the two mp3’s into one in Audacity and export them as a .wav file to my laptop, and then download it to my phone, will the Subliminals and the binaural beats still be present?
Sorry if I has been asked before, I couldn’t locate it if it was.

I don’t know anything about “subliminal binaural beats” but the MP3 is able to make a file 1/5th or 1/10th the size of the original is by throwing-away sounds that you can’t hear. So if you want to preserve something that you can’t hear it’s best to avoid lossy compression.

If I merge the two mp3’s into one in Audacity

What do you mean by “merge”? If you combine them so they play in sequence and stick with a lossless format, nothing in the audio should be changed. If you mix them so they play at the same time… Who knows???
