Abstract

The authors previously introduced the measurement software EASERA SysTune which can be used for measurements with live music and speech signals. In this work, we discuss specifically the use of real-time measurements for the time alignment of loudspeaker arrays and distributed systems and for the optimal adjustment of their phase relationships. Being capable of deriving impulse responses of up to 12 seconds length, the measuring process with EASERA SysTune is simpler and more accurate as the real-time function provides a more immediate view on the tuning process. Because measurements can be performed with standard stimulus signals as well as with external speech and music signals, fine-tuning loudspeaker settings becomes possible even during the rehearsal time of the musicians. Required measurement conditions and limitations are given.
