Abstract:
1. An apparatus, comprising: one or more processors; and one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus at least to: create one or more first data streams by processing one or more first audio signals from at least a first microphone and a second microphone receiving an acoustic signal from a sound source, wherein the at least the first microphone and the second microphone receive the acoustic signal at a respective time dependent on a corresponding distance of each microphone from the sound source and the one or more audio signals contain a directional component of the acoustic signal dependent on the corresponding distance of each microphone from the sound source; create one or more second data streams by processing one or more second audio signals from the at least the first microphone and the second microphone receiving the acoustic signal from the sound source, wherein the processing of the one or more second audio signals comprising detecting phase information from at least one of the one or more second audio signals, wherein the one or more second audio signals contain an ambient component of the acoustic signal, and wherein at least one of the one or more second data streams are created without the phase information to remove at least a portion of phase information from the ambient component from said at least one of the one or more second data streams to reduce a number of data bits required to transmit the ambient component of the acoustic signal; and output the one or more first data streams and the one or more second data streams, wherein the output includes a representation of the acoustic signal dependent on the directional component and the ambient component.
