How to make terrible audio quality when there is loud audio?

I would like to make audio quality similar to this (at 0:12) in Audacity.

Try playing with the “Distortion” effect:

The “Hard Clipping” setting will probably be close, but you may like to try other settings.

Also, reducing the sample rate (“Tracks menu > Resample”) will make the sound more muffled. Try resampling down to 8000 Hz (the smaller the number, the more muffled it will be).

“Helmet radio” plugin gives good clipping, without the result being deafeningly loud
severe clipping (without being deafeningly loud).png
