1. An audio processing apparatus, comprising:
- an acquirer that acquires a surrounding audio signal indicating a sound surrounding a user;
an audio extractor that extracts, from the acquired surrounding audio signal, (1) a main sound that is output without delay, (2) a providing audio signal, including prioritized sounds other than the main signal, that is stored and selectably output with or without delay, and (3) sounds that are not stored and do not need to be output;
a selector that selects one of a plurality of output patterns of audio signals; and
an output that outputs a first audio signal indicating a main sound and the providing audio signal,wherein the selector selects any one of (i) a first output pattern in which the providing audio signal is output along with the main sound without a delay, (ii) a second output pattern in which the providing audio signal is output with a delay after only the main sound is output, and (iii) a third output pattern in which only the main sound is output.

11. An audio processing method, comprising:
-
acquiring a surrounding audio signal indicating a sound surrounding a user; extracting, from the acquired surrounding audio signal, (1) a main sound that is output without delay, (2) a providing audio signal, including prioritized sounds other than the main signal, that is stored and selectably output with or without delay, and (3) sounds that are not stored and do not need to be output; selecting one of a plurality of output patterns of audio signals; and outputting a first audio signal indicating a main sound and the providing audio signal, wherein the selecting selects any one of (i) a first output pattern in which the providing audio signal is output along with the main sound without a delay, (ii) a second output pattern in which the providing audio signal is output with a delay after only the main sound is output, and (iii) a third output pattern in which only the main sound is output.

12. A non-transitory computer-readable recording medium having a program to be used in an audio processing apparatus recorded thereon, the program causing a computer of the audio processing apparatus to perform a method comprising:
-
acquiring a surrounding audio signal indicating a sound surrounding a user; extracting, from the acquired surrounding audio signal, (1) a main sound that is output without delay, (2) a providing audio signal, including prioritized sounds other than the main signal, that is stored and selectably output with or without delay, and (3) sounds that are not stored and do not need to be output; selecting one of a plurality of output patterns of audio signals; and outputting a first audio signal indicating a main sound and the providing audio signal, wherein the selecting selects any one of (i) a first output pattern in which the providing audio signal is output along with the main sound without a delay, (ii) a second output pattern in which the providing audio signal is output with a delay after only the main sound first audio signal is output, and (iii) a third output pattern in which only the main sound is output.
