Spatial audio processing apparatus
First Claim
1. An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured to with the at least one processor cause the apparatus at least to:
- determine a direction of each of at least two audio sources based on at least three microphone audio signals, wherein a respective direction of each audio source is relative to an actual position of a recording device comprising the at least three microphone audio signals;
cause to display a visual image for each audio source;
receive an indication to select a first audio source of the at least two audio sources based on the displayed visual image for each audio source;
generate a modified version of the selected first audio source, wherein the selected first audio source is modified at its determined direction with respect to a second audio source of the at least two audio sources;
process the at least three microphone audio signals based on the modified version of the selected first audio source and the second audio source, wherein the second audio source is unmodified; and
reproduce the processed at least three microphone audio signals in playback.

Abstract
An apparatus comprising: a directional analyser configured to determine a directional component of at least two audio signals; an estimator configured to determine at least one virtual position or direction relative to the actual position of the apparatus; and a signal generator configured to generate at least one further audio signal dependent on the at least one virtual position or direction relative to the actual position of the apparatus and the directional component of at least two audio signals.

17. A method comprising:
-
determining a direction of each of at least two audio sources based on at least three microphone audio signals, wherein a respective direction of each audio source is relative to an actual position of a recording device comprising the at least three microphone audio signals; causing to display a visual image for each audio source; receiving an indication to select a first audio source of the at least two audio sources based on the displayed visual image for each audio source; generating a modified version of the selected first audio source, wherein the selected first audio source is modified at its determined direction with respect to a second audio source of the at least two audio sources; processing the at least three microphone audio signals based on the modified version of the selected first audio source and the second audio source, wherein the second audio source is unmodified; and
reproducing the processed at least three microphone audio signals in playback. - View Dependent Claims (18, 19, 20)
