Currently I use sound measuring distance is such that the measured sound velocity of sound propagation time * == distance
Currently doing the subject, this theory is absolutely feasible.
My problem is not familiar to the API, ask to receive sound api which ah?
I know the transmission is AudioTrack, or receiving a MediaRecorder AudioRecorder, or other?
Someone has done a similar procedure?
Thank you

Theory is indeed feasible practical problems pile Bangding expect results

This feasible?

Certainly feasible, ah, there are generally mic noise reduction

It is not feasible, how do you know the phone receives voice is the sound you want to receive it, perhaps it outside noise
