AttackDecay

Attack Decay is a technique used in electronic music production to create dynamic sounds and textures. It refers to the combination of two envelopes used in signal processing: the Attack envelope and the Decay envelope.

The Attack envelope controls the rate at which a sound levels up to its maximum amplitude after a key press or note onset. This allows for the creation of sharp, percussive sounds or gradual, gentle increases in volume.

The Decay envelope controls the rate at which a sound levels down to its sustain level after the Attack phase. This allows for the creation of subtle, nuanced sounds or dramatic, dynamic declines in volume.

By adjusting the speed and shape of the Attack and Decay envelopes, musicians can create a wide range of timbres and textures. This technique is commonly used in synthesizers, drum machines, and other electronic instruments.

Attack Decay is a fundamental concept in electronic music production and has been used by a wide range of artists to create distinctive sounds. It is often combined with other techniques such as Sustain and Release (S/R) to create more complex and dynamic sounds.

The use of Attack Decay in music production dates back to the early days of electronic music. It has been popularized by artists such as Kraftwerk, Tangerine Dream, and many others. Today, it remains a key element in the sound design process and is used by musicians across a variety of genres.
