Pulse Waves

One of Evolver's analog oscillator shapes is a "pulse wave". A pulse wave goes immediately and abruptly from zero to full, stays there, then abruptly drops back to zero.

Evolver offers a range of pulse waves, with increasingly longer "pulse" periods. At P-01, the pulse period is so short it's basically nothing, and at P-99, the pulse period is so long, the "off" period is basically nothing. This is why at the extremes you don't hear any sound...it's like the oscillator isn't making a wave at all.

At P-50, the “on” period and “off” period are of equal duration. If this sounds like a square wave, that's because it is. A square wave is a pulse wave where the "on" and "off" portions are of equal size/duration. In other words, all square waves are pulse waves, but not all pulse waves are square waves.

Square waves have a particular bright and hollow sound (they only contain odd harmonics). They can be used to create a wide range of sounds.

Пила

Пилообразная волна — "типичный синтезаторный" звук. Пилообразные волны содержат все гармоники, они яркие и бурные в своём первичном состоянии. Производя все гармоники, они производят широкий спектр частот и очень хорошо фильтруются. Это одна из причин, по которой они стали настолько популярны за эти годы у производителей синтезаторов и программистов.
