ESS measurement with stereo analysis
ESS (Exponential Sine Sweep) provides much cleaner impulse response than claps. Take multiple measurements and average for best results.
Direction estimated from stereo phase difference. Distance from time delay. Brightness = intensity.
Save acoustic fingerprints of different rooms, then use "Identify" to recognize which room you're in based on acoustic signature.
Uses Exponential Sine Sweep (ESS) technique for impulse response measurement. Stereo microphones enable direction estimation via phase analysis. Based on research by Farina (AES 2007) and BatMapper (MobiSys 2017).
