Abstract
Examples disclose a method to receive a first audio signal at a first microphone positioned at an actual distance from a second microphone. Additionally, the examples disclose the method is further to receive a second audio signal at the second microphone, the second audio signal is associated with an actual time delay relative to the first audio signal. Also, the examples disclose the method is also to determine a virtual time delay corresponding to a virtual distance that is different from the actual distance and to obtain a spatial audio signal based the distances and the time delays.
