Press the button and bliss out on languid semiharmonic ambient tones.
|Waveform||sine triangle sawtooth square|
The basic audio element of this demo is a pair of simple waves of different frequencies, which are played in unison. You can pick among a few options for the basic waveform:
The notes played by this demo are picked randomly from two octaves in an equal-tempered pentatonic scale. This is not a scale that is often encountered in Western music, however it happens to make for note pairs and transitions that are pleasing to human ears.
The waveform is intentionally level-quantized to simulate low bit-depth. You can see this quantization in the oscilloscope as "stair steps" which are most visible in gently-sloping portions of the waveform. (That is, the stair steps are not a visual artifact from the oscilloscope rendering, but rather an accurate reflection of the waveform being generated.) In terms of the sound you hear, this quantization causes a quiet high-pitched "shimmering" effect.
