Abstract
Ambisonics audio such as may be used for computer simulations such as computer games is improved by improving the emulated spread of a sound source. A demanded spread for a sound object of a computer game is received, and using the spread one or more fractional Ambisonics orders are determined. Weights such as max-rE weights are derived for the fractional Ambisonics order using polynomial interpolation. An Ambisonics representation of the sound object is encoded using the weights for the fractional Ambisonics order for providing the sound object to an Ambisonics decoder to decode and play the sound object.
