Bitwise Logical Modulation

XOR Sound Examples

The samples are 44.1 kHz 16 bit mono WAVs, normalized to -6 dB level (be careful, some of the sounds are a bit buzzy). Each indivudal sample is 4 seconds long, unless otherwise stated.

• figure 1: additive, AM, XOR -- additive [pause] AM [pause] XOR
• figure 3: constant XOR -- A2=25 [pause] A2=49 [pause] A2=100 [pause] A2=100/A1=1
• figure 4: rectified sine
• figure 5: distorted waveshape plotted in fig. 2
• figure 6: morph between pulse - sawtooth - pulse (14 seconds)
• section 3.7: fat XOR distorted waveshape of above with S1/S2 detuning
• section 3.7: fatter XOR fat XOR of above with additional AM
