Original Abstract Submitted
A method for generating a spatial audio stream, the method including: obtaining at least two audio signals from at least two microphones; extracting from the at least two audio signals a first audio signal, the first audio signal including at least partially speech of a user; extracting from the at least two audio signals a second audio signal, wherein speech of the user is substantially not present within the second audio signal; and encoding the first audio signal and the second audio signal to generate the spatial audio stream such that a rendering of speech of the user to a controllable direction and/or distance is enabled.
