We tried to use unity to develop an APP, by ultrasonic filter to control toys, import the audio sampling rate is 44100 (16 bit), but after the unity play out sampling rate change makes toys can't response, played back through the native APP ultrasonic filter response can make toys,
Suspicion is the unity of the underlying do to audio file compression, to find a lot of information still not solve, I don't know whether what master have encountered such a problem,
Thank you very much!
