Some Physical Audio Effects

Changing Loop Gain	The sound of manual plucks as the loop gain is increased from zero.
Vibrato	A plucked guitar string with electromechanically induced vibrato. (There is no decay of the tone due to the compressor in the feedback loop.)
Vibrato with decay	A plucked guitar string with electromechanically induced vibrato. (The decay is due to k_G being decreased toward zero over time.)
Sustained ring modulation	The first clip in this sample is the chromatic scale as in the paper. The second clip is a solo line being played with the effect.
