of course not ... but the point is that the demonstration is accessible by all with a smartphone, ... and if the demonstration is successful then that can only lead to the development of cheap and small 'clip-on' gyro gysmos (available for $12.99).. that clip on to headsets or ear buds ... and then ambisonics is suddenly available to masses of people, for very cheap, and with a consistent and quality spatial experience (assuming the HRTF decoding can be done right).
