With the AR Spatial Analyzer module, you can instantly know how to accommodate for the depth difference and correct the time alignment. - Map The Volume The Volume Variance feature uses tagged locations to quickly map the sound level variations from tagged and labeled main speakers to your current position. The live values display in a 2D overlay allowing you to monitor the sound levels across the audience and keep the volume enjoyable for everyone. - Simplify Delay Timing The Delay Calc feature makes it simple to solve delay problems, calculating the delay timing between a tagged and labeled front speaker and delay stack. The displayed results give you the information needed to quickly sync your audio. 2) Diagnostic PEQ (in-app-purchase) Using the revolutionary real-time Diagnostic PEQ (parametric equalizer) module to listen to pink noise, receive recommended corrective EQ settings to implement for tuning your audio system, whether you’re in a large or small space.
