Abstract
A sound processing method obtains first audio data representing first sound, obtains second audio data representing second sound created in advance, analyzes the first audio data, compares the second audio data with an analysis result of the analyzing, reproduces third audio data from the second audio data by omitting a type of sound from the second sound that matches a type of sound in the first sound, based on a comparison result of the comparing, and outputs an audio signal representing the reproduced third audio data.
Claims15
A sound processing method for headphones, the method comprising:
- obtaining first audio data representing first sound from a microphone;
- obtaining second audio data representing second audio sound created in advance;
- analyzing the first audio data;
- comparing the second audio data with an analysis result of the analyzing;
- identifying a matching sound type in the second audio sound that matches a sound type in the first sound, based on a comparison result of the comparing;
- generate third audio data from non-matching sound types in the second audio sound by omitting the matching sound type in the second sound;
- and
- outputting an audio signal representing the generated third audio data.
A sound processing apparatus comprising:
- a memory storing instructions;
- and
- a processor that implements the instructions to:
- obtain first audio data representing first sound;
- obtain second audio data representing second audio sound created in advance;
- analyze the first audio data;
- compare the second audio data with an analysis result of the first audio data;
- identify a matching sound type in the second audio sound that matches a sound type in the first sound, based on a comparison result of the compare;
- generate third audio data from non-matching sound types in the second audio sound by omitting the matching sound type in the second sound;
- and
- output an audio signal corresponding to the generated third audio data.
A sound processing system comprising:
- a headphone;
- and
- a sound processing apparatus comprising:
- a memory storing instructions;
- and
- a processor that implements the instructions to:
- obtain first audio data representing first sound;
- obtain second audio data representing second audio sound created in advance;
- analyze the first audio data;
- compare the second audio data with an analysis result of the first audio data;
- identify a matching sound type in the second audio sound that matches a sound type in the first sound, based on a comparison result of the compare;
- generate third audio data from non-matching sound types in the second audio sound by omitting the matching sound type in the second sound;
- and
- output an audio signal corresponding to the generated third audio data to the headphone.
