Loudspeaker manufacturer EDC Acoustics has announced the introduction of Rapid, a new system tuning program designed for use exclusively with the company’s products.
Rapid is based on the EDC Acoustics Pro app, which provides for augmented reality loudspeaker configuration and setup through visual confirmation of defined audience coverage areas and real-time acoustical analysis and loudspeaker optimization. Instead of using augmented reality, the new Rapid app utilizes straightforward preset configurations to allow for faster analysis and optimization.
Additionally, Rapid enables users to deploy custom dispersion configurations by entering the room or audience dimensional information (back audience width, front audience width, back row distance, first row distance, speaker height, offset etc.). This allows users to define and commission an EDC loudspeaker system in short order.
The Rapid app uses the same backend as the Pro version, and matches more than 40 different energy curves for each cross section of audience, applying the most appropriate energy skew, dispersion angle and non-symmetrical offset to match each cross-section in both the horizontal and vertical axis. This is intended to ensure all audience spaces are matched in terms of both sound pressure levels and frequency response, stated to be typically within +/-2 dB of accuracy for all audience members. It does this while minimizing energy directed outside the defined room/audience shape to help lower room reverberation, reflections, and environmental noise spill.
Rapid also predicts the frequency response and level of more than 2,000 locations within the defined audience area, and the user can send a test sweep signal to be measured by the inbuilt iOS microphone that allows for comparative analysis of predicted VS measured frequency response and sound pressure level. This is designed to facilitate higher accuracy, as the error is fed back through algorithms to ensure the highest level of precision. An FIR filter is provided to allow the operator to better tune the loudspeakers to match the acoustics of any space and automatically deploy a FIR filter within seconds that is naturally phase linear.
Rapid supports mono and stereo EDC Loudspeaker arrays of any size, and it also supports no sub, mono sub, and stereo sub configurations. All EDC Acoustics algorithms and system optimizations work for both full range loudspeakers and sub arrays of three or more boxes.
Rapid is available for $35 at the Apple App Store.
