Based on the EDC Acoustics Pro app – which provides augmented reality loudspeaker configuration and set-up through visual confirmation of defined audience coverage areas and real-time acoustical analysis and loudspeaker optimisation – the new Rapid room tuning iOS app is designed for use exclusively with EDC Acoustics products.

Instead of using augmented reality, the Rapid app uses preset configurations to allow rapid analysis and optimisation of EDC Acoustic loudspeakers. Additionally, Rapid enables users to deploy custom dispersion configurations by simply 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 minutes.

The Rapid app uses the same backend as the Pro version, and still matches more than 40 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 ensures all audience spaces are matched in terms of both sound pressure levels and frequency response – typically within ±2dB of accuracy for all audience members. Equally notable, it does this while minimising energy directed outside the defined room/audience shape to addressroom reverberation, reflections and noise spill concerns.

Rapid also predicts the frequency response and level of more than 2,000 locations within the defined audience area, with the user able to 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 facilitates high accuracy, as the error is fed back through algorithms to ensure the highest level of precision. A real-world system FIR filter is provided, allowing the operator to tune the speakers to perfectly 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. It also supports no sub, mono sub, and stereo sub configurations. All EDC Acoustics algorithms and system optimisations work for both full range speakers and sub arrays of three or more boxes.
