Noise left after dithering and phase canceling a tone. A tone was created with Audacity's tone generator. Another version of the tone was made by downsampling and dithering the original tone in Ableton Live. I then phase cancelled the two sounds by switching the polarity of one of the tones and blending them back together in Audacity. Because of the phase canceling, none of the original tone can be heard. Only the noise added during dithering remains.
