Concluding Thoughts on Distortion

Module by: Elizabeth Gregory, Jason Buck

Summary: In our conclusion, we compare our original signal with our favorite distortion signal.

In the end, we found our perfect distortion (plus a bit of noise we couldn't quite get out). Taking a look at the spectrograms for our music sample and our distorted musical sample, we can see which harmonics were emphasized to create the distortion.

Music Sample: Everlong by the Foo Fighters

More importantly, we can hear the wonderful difference between the two sound clips, the original Foo Fighters' Everlong clip and the distorted version.

To test the overall quality of our distortion, we can also listen to how our distorted sample sounds in comparison to an Marshall AVT-50 amplifier.

All in all, this is a great method for simple distortion! The next step would be to map the pertinent terms from our Taylor Series to "nobs" in order to increase or decrease each coefficient to change the distortion.
