Abstract
An audio signal processing device includes a sound acquisition unit configured to acquire audio data generated by collecting a sound in a sound collection target space, a selection unit configured to select, based on a priority of each of a plurality of areas in the sound collection target space, one or more of the areas in the sound collection target space, and an output unit configured to output processed data, for which predetermined signal processing for the areas selected by the selection unit is executed on the audio data acquired by the sound acquisition unit, and the predetermined signal processing for an area not selected by the selection unit is not executed on the audio data.
Claims20
An audio signal processing apparatus comprising:
- at least one hardware processor;
- and
- a memory which stores instructions executable by the at least one hardware processor to cause the audio signal processing apparatus to perform at least:
- acquiring audio data generated by collecting a sound in a sound collection target space;
- determining a priority of at least one of a plurality of areas in the sound collection target space;
- and
- outputting, based on the audio data acquired in the acquiring, first processed data obtained by first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining;
- and
- outputting, based on the audio data acquired in the acquiring, second processed data obtained by second predetermined signal processing for sound of areas including an area different from the one or more areas selected based on the priority determined in the determining, after outputting the first processed data obtained by the first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining.
An audio signal processing method comprising:
- acquiring audio data generated by collecting a sound in a sound collection target space;
- determining a priority of at least one of a plurality of areas in the sound collection target space;
- and
- outputting, based on the audio data acquired in the acquiring, first processed data obtained by first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining;
- and
- outputting, based on the audio data acquired in the acquiring, second processed data obtained by second predetermined signal processing for sound of areas including an area different from the one or more areas selected based on the priority determined in the determining, after outputting the first processed data obtained by the first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining.
A storage medium storing a program for causing a computer to execute an audio signal processing method, the audio signal processing method comprising:
- acquiring audio data generated by collecting a sound in a sound collection target space;
- determining a priority of at least one of a plurality of areas in the sound collection target space;
- and
- outputting, based on the audio data acquired in the acquiring, first processed data obtained by first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining;
- and
- outputting, based on the audio data acquired in the acquiring, second processed data obtained by second predetermined signal processing for sound of areas including an area different from the one or more areas selected based on the priority determined in the determining, after outputting the first processed data obtained by the first predetermined signal processing for sound of the one or more areas selected based on the priority determined in the determining.
