TECHNOLOGY | Use Adobe Audition to spy on chatty demons

Even a cheap cellphone placed on the floor with the sound recorder on can pick up demonic/human conversation in almost any room in your house, including the basement and attic, with the help of sound-processing software, such as Adobe Audition (free for 30 days at
Adobe Audition can be downloaded and used for free for 30 days
This article helps you get started with spying on roommates or finding out what the ghosts in your attic are up to using a real-world audio file (made on a Huawei Ascend M860) of humans and demons collaborating in the basement of my current residence, and using Adobe Audition to cull conversation from the background noise.

So, here's how to get started on the path to a career in demon or human (or both) espionage:
  1. Download the 'before' audio file from MediaFire and, then, open it with Adobe Audition.

  2. In Audition, increase the volume by 30 dB by rotating the knob on this palette twice to the right:

  3. Select the region of the audio track as shown (approx. 2:20 to 3:50):

  4. On the Effects menu, point to Noise Reduction / Restoration, and then click Adaptive Noise Reduction; then, on the Effect - Adaptive Noise Reduction palette (below), adjust the settings as shown:

  5. Finally, press the space bar to start playing the file.
You will hear many overlapping voices, so adjust the various sliders on the palette until you have isolated one or two, and then listen. Experiment with the combinations that work best.

You can then download the 'after' file to compare your results with mine.

If you are unable to make this work for you, simply let me know at
