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.
