Abstract: A signal processing device includes phase rotation units which rotate a phase of a signal A and generate two signals having a phase difference of θ, and a control unit which performs transition of θ over time. The control unit controls phases so that θ is approximately 0 degrees at a time point T0 and θ is approximately 180 degrees at a time point T1.

Abstract: An audio communication device includes: a sound position determiner that determines sound localization positions for N audio signals in a virtual space having first and second walls; N sound localizers each performing sound localization processing to localize sound in the sound localization position determined by the sound position determiner, and outputting localized sound signals; an adder that sums the N localized sound signals, and outputs a summed localized sound signal. Each sound localizer performs the processing using: a first head-related transfer function (HRTF) assuming that a sound wave emitted from the sound localization position of the sound localizer determined by the sound position determiner directly reaches each ear of a hearer virtually present at the hearer position; and a second HRTF assuming that the sound wave emitted from the sound localization position reaches each ear of the hearer after being reflected by closer one of the first and second walls.

Abstract: An audio signal processor includes: a first amplifier that amplifies a first audio content; a mixer that mixes an output signal of the first amplifier and a second audio content; a second amplifier that amplifies an output signal of the mixer; and a setter that sets an amplification amount of the first amplifier. The setter sets an amplification amount in the first amplifier so that the amplification amount in the first amplifier cancels an amplification amount in the second amplifier.

Abstract: An acoustic signal processing device includes: a front signal processor which generates first L and R signals by performing signal processing on a first signal which is a front channel signal; a first adder which generates a fourth signal which is a left channel signal by adding the first L signal and a second signal which is a left channel signal; and a second adder which generates a fifth signal which is a right channel signal by adding the first R signal and a third signal which is a right channel signal. The front signal processor generates the first L and R signals by signal processing in which the first signal is distributed and placed at predetermined positions when the first signal is a dialog signal, and distributed and placed at positions different from the predetermined positions when the first signal is not a dialog signal.
