The most basic wave of all is the sine wave, which contains no harmonic overtones at all, leaving just a single wave which goes up and down in a very symmetrical cycle. How frequent this wave ...

Sine-wave speech can be thought of as a sort of auditory illusion, a sensory edge case in which one’s experience has a clear “before” and “after” moment, like going through a one-way door.

The basic model for the waveguide uses a delay line of p samples ... introducing a noise burst whose spectrum decays to a sine wave at a rate proportional to the length of the delay line. The model ...
