Audio signal processing device, audio signal processing method, and control program

An audio signal processing method for outputting an output signal data string in accordance with an input signal data string generated through sampling based on an audio signal string by using a neural network circuit that includes an input layer including a plurality of input units, an intermediate layer, and an output layer including a plurality of output units, the audio signal processing method comprising:

• executing simultaneous inputting of, at each of unit time intervals, each of pieces of unit data of a plurality of consecutive sampling units in the input signal data string into each of the plurality of input units on a one-to-one basis,
• wherein one of the pieces of unit data input into one of the plurality of input units at one of the unit time intervals is input into another of the plurality of input units at another of the unit time intervals in the simultaneous inputting at each of the unit time intervals;
• and
• outputting, in accordance with the simultaneous inputting over a plurality of the unit time intervals that are consecutive, a computation result at each of the unit time intervals as an element of the output signal data string, the computation result being based on pieces of data output from the plurality of output units at each of the plurality of unit time intervals.
