The intriguing thing about recording EMF is that the frequency spectrum you get is much richer than what you get from a regular microphone (check the attached spectrogram).

This means that you can use extreme pitch shifts and get results that sound completely different from your original recordings.

Check out an example of some extreme pitch-shifted emf recordings on the attached .wav files, with which you can create music!
