             | The human ear is sensitive to phase correlation. It stems
             | from the physiological fact that our ear is effectively a
             | multiresolution filter. So with an overtone-rich tone, the
             | time constant with which we perceive the uppermost
             | harmonics is significantly less than the period of the base
             | harmonic. So if the sonic energy of those harmonics is
             | correlated into small "packets", we hear that as a
             | "buzzing". This is true of raw synthesis waveforms:
             | sawtooth, square, etc. It's also true of any short
             | transients: clapping, hi-hats, etc.
             | 
             | If you "mess with" the phase information of the harmonics
             | relative to the base harmonic, this is the same thing as
             | changing where the sonic energy of those harmonics falls in
             | the wavecycle. So notably, in the cases listed above where
             | the sonic energy falls into small "packets", if you
             | randomize that phase information relative to a much lower
             | tone (as Paulstretch does), you now have spread that energy
             | throughout the full wavecycle. This eliminates any
             | sensation of "buzzing" or "clicking" and makes transients
             | "mushy".

               | I'm not sure any literature on this beyond my own
               | experience.
               | 
               | In the context of synthesizers, "buzzing" quality is
               | associated with unfiltered basic waveforms: sawtooth,
               | square, triangle (to a lesser extent), pulse (notably
               | so). A sawtooth wave is used, for example, as the bass
               | sound in Gorillaz' "DARE".
               | 
               | More generally, in my personal experiments, "buzzing" is
               | associated with the presence of discontinuities in the
               | waveform (i.e., the Dirac delta and its antiderivatives).
               | Any discontinuity is associated with sonic energy at all
               | frequencies, at a highly localised point in time. (See
               | the Fourier transform of Dirac delta (anti)derivatives
               | here [1].) Higher antiderivatives of the Dirac delta have
               | progressively less energy at higher frequencies; beyond
               | the 2nd antiderivative buzzing is not really audible.
               | 
               | Aside - a pulse wave is a series of Dirac deltas; a
               | sawtooth is the 1st-order antiderivative thereof; a
               | square wave is a series of sign-alternating 1st-order
               | Dirac delta antiderivatives; and a triangle wave is
               | alternating 2nd-order Dirac delta antiderivatives. Hence
               | - buzziness in these waveforms.
               | 
               | The human ear has a Q of about 15 (very approximate) -
               | meaning its response at any frequency lasts for about 15
               | cycles of that frequency. So, when presented with a
               | periodic discontinuity (e.g. sawtooth wave), the sonic
               | content below about 15 times the base frequency will tend
               | to cohere together into a tone, while the sonic content
               | above 10 times the base frequency will tend to be
               | perceived independently of frequency - as a buzzing. (See
               | Bell, "A Resonance Approach to Cochlear Mechanics".)
               | 
               | So, if you want to increase the amount of buzzing in a
               | waveform, you can add localized "packets" of high-
               | frequency sonic energy up to a rate 1/15 that of the
               | lowest frequency content of said packets. You can
               | experiment with this in Audacity by generating sawtooth
               | waves of various frequencies (between 25-250 Hz, where
               | buzzing is easily audible) and low- and high-passing them
               | appropriately to separate the "tonal" (low-frequency)
               | content from the "buzz" (high-frequency) content. Then
               | mix and match the two from different frequency waveforms
               | two create a waveform at your desired base frequency with
               | your desired rate of buzzing.
               | 
               | Finally, a more pedestrian - and very common - way that
               | the above is achieved is the synthesis technique known as
               | "supersaw", by which a handful of slightly-detuned
               | sawtooth waves are mixed together. Beside giving a
               | "shimmering" effect which one gets from mixing any
               | slightly-detuned sounds together, this also results in
               | increased "buzziness". This effect is very common in pop
               | electronic music. E.g. the bass sound in Lady Gaga's
               | "Just Dance" is a good example.

             | 
             | The effect is most noticeable on raw synthesized tones:

             | The ear can hear this, as a "buzzing sound".
             | 
             | Run these tones through Paulstretch (even with 0 stretch),
             | and the sonic energy is distributed throughout the
             | wavecycle. These tones retain their spectral character, but
             | noticeably lose the buzzing character.
             | 
             | I've uploaded a demo here:
             | https://chris.pacejo.net/temp/phase.wav It is a 55 Hz

             | tone, and the tone fed through Paulstretch with no
             | stretching.
             | 
             | There was even a paper written on this. Laitinen, Disch &

             | Spectrum". [1]
             | 
             | Paulstretch muddies up percussive transients (like hi hat
             | strikes) as well.
             | 
             | Anyway it's the reason things like gammatone filters exist
             | for analyzing audio. They reveal phase correlations in the
             | same way the ear is able to. Windowed Fourier transforms
             | (used by e.g. Paulstretch and Audacity for various
             | purposes) obfuscate these relationships.

       | it doesn't preserve pitch) plus things like reverb and delay
       | effects
       | 
       | Here's some slowed-down ambient music:

         | Fun fact: it seems to be somewhere around 33 beats per minute
         | that people lose the connection between one beat and the next

         | It's not exactly for 1/1, but scroll down to "Deconstructing
         | 2/1" or "Deconstructing 1/2", then down to the music staves
         | section - Hit "Start All", then roll the dice, and it will
