Envelope

Envelopes are useful in recreating more life-like sounds with variable characteristics.
They are responsible for sound being short and punchy or long and sustained!

An envelope does this by controlling 4 characteristics - Attack, Decay, Sustain and Release.

• Attack - Controls how quickly sound goes from zero to full volume when triggered

• Decay and Sustain - Control how quickly sound goes from full volume to sustained volume after the attack

• Release - Controls how quickly sound goes from any level to zero when triggered
