Signal processing apparatus and method of generating audio signal

An audio processing method comprising:

• obtaining sound data based on sound collection by one or more microphones, wherein the obtained sound data includes data of a sound in an area subject to image capturing from different directions by a plurality of image capturing devices;
• and
• generating, as audio data to be played with a virtual-viewpoint image that is a moving image representing a view of the area at one point of time from a moving virtual viewpoint, audio data of a sound collection period around the one point of time based on the obtained sound data, wherein the virtual-viewpoint image is generated based on a plurality of images obtained respectively by the plurality of image capturing devices.
