Caution if you are wearing headphones: extremely loud sounds
To perform on any device with a web browser, ideally on a smartphone. Variable duration.
Uses HTML5 Web Audio API. It is currently compatible with most modern desktop
browsers, Chrome on Android phones and Chrome or Safari on iPhones.
Develop the performance by subsequently adding individual notes to the repeating sound mix.
Specify the individual note to be added by setting its relation to the given ground frequency.
This you do by changing the multiplier and divisor. The new note will be M/D*F, where M
is the multiplier, D the divisor, and F the main frequency. Generally you should increase
or decrease either multiplier or divisor in turn, always in a different order. For example:
1/1, 2/1, 3/1, 3/2, 4/2, 4/3, 5/3, 5/2, etc. Thus the growing sound mass should increase
according to some variation on the harmonic series of the ground frequency. Each new note
is added to the tone mix at a randomly selected place inside the repeating time cell.
Each change is introduced to the sound mix by pressing the Submit button or swiping right on
the Swipe panel. Occasionally, do one of the following changes:
When the overall sound becomes close to noise and the component frequencies become
barely recognizable, change the Overwrite switch from 0 to 1 for several notes in a
row, then change it back to 0. When the Overwrite switch is 1, the new notes overwrite the
existing sound mix, otherwise they are added to the existing sound mix.
Change the tonality by changing the Ground Frequency. It can be done in
a smaller or bigger steps, or though a combination of smaller or bigger steps. An entire section
can be created by changing tonality stepwise, instead of changing the multiplier and divisor.
Double or halve the length of the repeating time cell, by doubling or halving either the
Meter or the Duration. This impacts the tempo. Do have slower and faster sections in your
performance.
Change the tone color and length of the newly added notes by altering either the Reverb
or the Inverse Decay Rate or both.
The sound resolution is 44100 samples per second, but only 1 bit per sample, which, apart from
the characteristic noisy sound, creates a direct link between tone intervals and resulting
sound color.
