waveform - Can I measure distances with sound in an android app? -


i've got number of questions time, although relate same problem: wanted build rudimentary sonar in android, , have no clue how possible such thing.

  • is can work reasonably well?
  • what's best way (that makes sense in mobile app) compare waveforms?
  • can reliably measure delay between sending , receiving given waveform in small-ish enclosure(say, room)?
  • is there way (that makes sense in mobile app) discard noise created by, instance, uneven surfaces (say, open doors)?

just trying oriented here, i'm really new sound processing in mobile apps. in advance!
