A processor of a filter generation device according to an embodiment includes an extraction unit that extracts a first signal having a first number of samples from samples preceding a boundary sample of a sound pickup signal, a signal generation unit that generates a second signal containing a direct sound from a sound source and having a second number of samples larger than the first number of samples based on the first signal, a transform unit that transforms the second signal into a frequency domain and generates a spectrum, a correction unit that increases a value of the spectrum in a correction band and generates a corrected spectrum, an inverse transform unit that inversely transforms the corrected spectrum into a time domain and generates a corrected signal, and a generation unit that generates a filter based on the sound pickup signal and the corrected signal.
A filter generation device comprising:
A filter generation method of generating a filter in accordance with transfer characteristics by picking up a measurement signal output from a sound source with use of a microphone, comprising:
A non-transitory computer readable medium storing a program causing a computer to execute a filter generation method of generating a filter in accordance with transfer characteristics by picking up a measurement signal output from a sound source with use of a microphone, the filter generation method comprising:
