The present disclosure relates to a signal processing device, a signal processing method, and a program that allows for generating an input signal suitable for a multi-way speaker. A band dividing unit divides an audio signal into signals in a plurality of bands corresponding to respective bands of a plurality of speaker units of the multi-way speaker. A filter processing unit performs wave front synthesis filter processing on each of the audio signals in the respective bands having been divided into. The audio signal in each of the bands after the wave front synthesis filter processing is supplied to the speaker unit of the corresponding band in the multi-way speaker. The present disclosure is applicable, for example, to a signal processing device or other devices.

A signal processing device includes: a calculating unit performing calculation using signal levels of first and second acoustic signals; a determining unit, based on a result of a comparison between: the signal level of at least one of the first and second acoustic signals before the calculation; and a result of the calculation, determining whether a component of a third acoustic signal to be output from a position between a position from which the first acoustic signal is output and a position from which the second acoustic signal is output is included in the first and second acoustic signals; and a signal generating unit generating the third acoustic signal from the first and second acoustic signals when the determining unit determines that the component of the third acoustic signal is included in the first and second acoustic signals.

A system for listening to binaural audio through a plurality of speakers having at least two pair of speakers, incorporating applying at least two Crosstalk Cancellation Filter to a corresponding at least two binaural signals to create a corresponding at least two pair of speaker signals, and inputting the at least two pairs of speakers signals to a corresponding at least two pairs of speakers of a plurality of speakers. The invention also relates to a system and method for listening to binaural audio through a plurality of speakers by dividing the speakers into groups, generating a Crosstalk Cancellation Filter for each group, and distributing the binaural audio among the speaker groups. The invention also relates to a system for placing a binaural audio signal onto a plurality of pairs of cross talk cancelled loudspeakers.

Methods and systems for positioning audio signals on virtual soundstages. The mobile device may include one or more orientation components that are used to generate orientation data that track directional changes that are used to position an audio signal on a virtual soundstage. A listener of the sound from the audio signal may be associated with the orientation data such that the positioning of the audio signal provides virtual acoustic presence on the virtual soundstage. The audio signal is received, the audio signal may be associated with a plurality audio channels. The orientation data for positioning the audio signal is also received. A position for the audio signal on the virtual soundstage is determined based in part on the orientation data. The audio signal is then positioned on the virtual soundstage.

Example techniques involve outputting multiple audio channels using a multiple driver playback device. An example playback device receives a first and second channel of audio content. The playback device plays back play back the first channel via a first group of audio transducers such that the first group of audio transducers form, via superposition, a first response lobe having a maximum in a first direction. Further, the playback device plays back the second channel via a second group of audio transducers such that the second group of audio transducers form, via superposition, a second response lobe having a maximum in a second direction that is separated by an angle of at least 45° from the first direction.

Methods, systems, computer-readable media, and apparatuses for audio signal processing are presented. Some configurations include determining that first audio activity in at least one microphone signal is voice activity; determining whether the voice activity is voice activity of a participant in an application session active on a device; based at least on a result of the determining whether the voice activity is voice activity of a participant in the application session, generating an antinoise signal to cancel the first audio activity; and by a loudspeaker, producing an acoustic signal that is based on the antinoise signal. Applications relating to shared virtual spaces are described.

A virtual reproduction signal generation unit generates a virtual reproduction signal based on a sound pickup signal of a stereophonic sound at a listening position in a compartment, assuming that virtual speakers are respectively located at portions of Np positions in a vehicle, the virtual reproduction signal causing the virtual speakers of the Np positions to reproduce the stereophonic sound. A virtual prediction signal generation unit generates a virtual prediction signal based on the virtual reproduction signal and an information representing a change of acoustic characteristics when at least part of the portions of the Np positions is changed, the virtual prediction signal causing the virtual speakers of the Np positions to output a predicted sound at the listening position. An output signal generation unit generates an output signal based on the virtual prediction signal, the output signal causing speakers of a plurality of positions to output the predicted sound.
