This is a set of scope images taken during an analysis of Reason’s Scream 4 Sound Destruction Unit. Original Signals - Sawtooth wave generated by a Thor Polysonic Synth in Reason 4.0

Overdrive Algorithm - Despite the transformation of the signal, the phase generally follows the sawtooth phase

Distortion Algorithm - The signal processing is slightly different from the overdrive algorithm. It’s difficult to see the difference on these small images.

Fuzz Algorithm - More harmonic characteristics introduced beyond that of the overdrive and distortion algorithms.

Tube Algorithm - Notice that this function also inverts the phase of the sawtooth wave.

Tape Algorithm - See the related post

Feedback Algorithm - The general phase of the sawtooth is normal with the feedback algorithm as ringing harmonics are introduced.

Modulate Algorithm - The sawtooth takes on characteristics of frequency modulation.

Warp Algorithm - Again the sawtooth characteristics are still in phase with the original as the signal is modulated.

Digital Algorithm - The staircase output is typical of the wordlength reduction effect aka bitcrushing.

Scream Algorithm - the sawtooth takes on formant characteristics after processing.
