  2. Binaural Recording • Binaural is to the ears what binocular is to the eyes • – Stereo recording, but better • – The highest fidelity recording system available • Far field recording challenge • – Binaural summation produces a 10dB boost…which is the perceptual equivalent of asking someone to speak up • Benefits of spatial audio • – 3-dimensional sound produces a strong sense of presence • – Allows the listener to distinguish voices based on location and to selectively tune out unwanted sounds • – Note: binaural microphones are required to record spatial audio, but any earphones can play the 3D recordings back

  3. Dot Positioning System • Two-Dimensional Barcode • Camera in pen tip reads 6 x 6 dot region • Each dot can have 1 of 4 positions • 4^36 = 4.72 x 10^21 • Practically speaking, that’s > 7 trillion unique notebook pages
