AB  - Line source arrays (LSAs) are used for large-scale sound reinforcement aiming at sound fields that are as homoge-neous as possible over the whole audio bandwidth. The deployed loudspeaker cabinets are rigged with different tilt angles and/or are electronically controlled in order to provide the intended coverage of the audience zones and to avoid radiation towards reflective ceilings, sidewalls or residential areas. In this contribution, enhancements of the analytical polygonal audience line curving (PALC) approach are presented. PALC was introduced for finding appropriate LSA cabinet tilt angles with respect to the geometry of the receiver area and the intended coverage. The PALC extension includes methods to use discrete sets of inter cabinet tilt angles, to control the target coverage by using weighting factors and to deal with non-continuous audience lines, i.e., zones which are not to be reinforced. The extended PALC is evaluated in comparison with a typical standard LSA curving scheme. An implementation of PALC is provided as an open web application.
