Hoover sound

The famous Dominator "hoover sound" first heard unaltered, then put through a phaser effect and the EG Attack levels altered.

Hoover sound refers to a particular synthesizer sound in electronic music, commonly used in rave techno, hardcore techno, gabber, breakbeat hardcore, trance, hard house and hard NRG. Originally called the "Mentasm", the name that stuck was the one likening the sound to that of a vacuum cleaner (often referred to via the genericized trademark "hoover" in the UK and Ireland).
