That’s not how this works at all…
The craze about files being encoded in WAV was a result of the subliminal community’s poor understanding of technology. Specifically, makers were creating ultrasonic subliminals (which do work), but some of those makers then decided to upload them to YouTube, which immediately broke them because YouTube’s encoding process’s compression automatically removes all inaudible ultrasonic frequencies.
So, people needed a way to get these ultrasonic subliminals in a file-format that retained all the encoded sounds, not just the audible ones. Somehow people decided the best option was to use music technology originally released in 1991, the WAV format.
None of this has anything to do with audio that serves to anchor in energetic programming or morphic fields. Complete apples to oranges comparison.
