Abstract
A sound signal processing device includes a plurality of sound signal processing units and a plurality of buffers. Each of the plurality of sound signal processing units belongs to one of a plurality of groups and executes a predetermined process by using a supplied sound signal. The plurality of buffers are provided with mutually different buffer sizes where each of the plurality of buffers is associated with one of the groups and supplies an accumulated sound signal to a sound signal processing unit that belongs to an associated group.
Claims5
A sound signal processing device, comprising:
- a plurality of sound signal processing units where each of the plurality of sound signal processing units belongs to a respective group of a plurality of groups and executes a predetermined process by using a supplied sound signal;
- and
- a plurality of buffers that are provided with mutually different buffer sizes where each of the plurality of buffers is associated with one of the groups and supplies an accumulated sound signal to a respective sound signal processing unit of the plurality of sound signal processing units that belongs to an associated group of the plurality of groups, wherein
- two or more sound signal processing units of the plurality of sound signal processing units belong to a first group of the plurality of groups, and
- a first buffer of the plurality of buffers that is associated with the first group supplies the accumulated sound signal to the two or more sound signal processing units.
A sound signal processing method that is executed by a sound signal processing device that includes a plurality of sound signal processing units where each of the plurality of sound signal processing units belongs to a respective group of a plurality of groups and a plurality of buffers that are provided with mutually different buffer sizes where each of the plurality of buffers is associated with one of the groups, the method comprising:
- supplying, by each of the plurality of buffers, an accumulated sound signal to a respective sound signal processing unit of the plurality of sound signal processing units that belongs to an associated group;
- and
- executing, by each sound signal processing unit, a predetermined process by using a supplied sound signal, wherein
- two or more sound signal processing units of the plurality of sound signal processing units belong to a first group of the plurality of groups, and
- a first buffer of the plurality of buffers that is associated with the first group supplies the accumulated sound signal to the two or more sound signal processing units.
A sound signal processing device, comprising:
- a plurality of sound signal processing units that execute predetermined processes by using supplied sound signals;
- and
- a plurality of buffers that accumulate sound signals with mutually different sizes and supply accumulated sound signals to the plurality of sound signal processing units, wherein
- each of the plurality of sound signal processing units receives a respective accumulated sound signal from a respective buffer of the plurality of buffers that accumulates the sound signal with a size that is needed for the predetermined process of each of the plurality of sound signal processing units, and
- two or more sound signal processing units of the plurality of sound signal processing units that execute the predetermined process by using the sound signal with an identical size, receive the sound signal with the identical size from one of the plurality of buffers.
