Manufacturers typically provide a spreadsheet or custom program to design arrays. Examples include L-Acoustics SOUNDVISION, Adamson Shooter, Electro-Voice LAPS (Line Array Prediction Software), D&B Audiotechnik ArrayCalc, and JBL Vertec Line Array Calculator. Renkus Heinz offers a program called EaseFocus. It is similar to EASE but has only features and calculations specific to Line arrays. EaseFocus has data for a large number of manufacturers allowing comparison of several loudspeaker systems. Other line array brands that use EaseFocus include Bose Professional, Community Professional Loudspeakers, Electro-Voice, QSC, RCF, and VUE Audiotechnik. Meyer Sound offers a different solution by providing an online system called MAPP Online Pro. Nexo offer their 3D modelling software, NS1.
