Pronunciation: [ˈadsə] (IPA) 
ADSR is an acronym used in music production which stands for Attack, Decay, Sustain, and Release. The IPA phonetic transcription of this word is /ædɛsɑr/. The first two letters "AD" are pronounced as the vowel sound /æ/ and the consonant sound /d/. The letters "SR" are pronounced as the vowel sound /ɑ/ and the consonant sound /r/. The correct spelling of ADSR is important in music production as it relates to the manipulation of sound waves.
ADSR is an acronym that stands for Attack, Decay, Sustain, and Release. It refers to the four main parameters that determine the envelope shape of a sound waveform in music synthesis and production.
Attack refers to the initial phase of a sound, during which the sound gradually builds up from silence to its maximum level. It determines how quickly the sound reaches its peak volume.
Decay refers to the decrease in volume after the attack phase. It represents the time it takes for the sound to reduce from its peak level to the sustain level.
Sustain refers to the level at which the sound remains after the decay phase. It represents the steady-state portion of the sound, where it holds its volume until the key is released.
Release refers to the final phase of the sound, starting from when the key is released until the sound completely fades out. It determines how long it takes for the sound to return to silence after the key is released.
ADSR envelopes are utilized in various electronic musical instruments and synthesizers to shape and control the characteristics and dynamics of sounds. By adjusting the parameters of ADSR, musicians and producers can manipulate the attack time, decay rate, sustain level, and release time of a sound, resulting in the creation of various textures, tones, and effects in music production. The ADSR model provides a concise way for sound designers to shape and control the temporal aspects of a sound waveform.
