envelope modulation的意思|示意

Envelope modulation is a type of audio processing technique used in modern synthesizers and musical effects processors. It involves using an envelope, or a series of envelopes, to shape the timing, amplitude and overall sound of a signal.

Envelope modulation uses a series of five parameters to control the sound of a signal. The five parameters are commonly referred to as attack, decay, sustain, release and level. Each of these parameters controls a different aspect of the sound. The attack, or attack time, is the time it takes for the sound to rise from its initial level to its peak volume. The decay, or decay time, is the time it takes for the sound to fall from its peak volume to the sustain level. The sustain, or sustain level, is the point at which the sound remains for a set period of time. The release, or release time, is the time it takes for the sound to fade away after the sustain level is reached. The level is the overall volume of the signal.

Envelope modulation can be used to create a wide variety of sounds, from subtle sonic shifts to drastic sonic transformations. It can be used to emphasize certain frequencies, reduce the dynamic range of a signal, or even create new timbres. Envelope modulation is commonly used to create musical effects such as vibrato, tremolo, chorus, and flanging.

It’s also used to add motion to otherwise static sounds. For example, some synthesizers and samplers will use envelope modulation to vary the pitch or volume of a sound over time. This can be used to create some interesting and complex textures. Envelope modulation is also used to create transitions from one sound to the next.

Envelope modulation is a powerful tool for shaping audio. Whether you’re creating music, sound design or Foley effects, envelope modulation can help you create the perfect sound.
