An audio signal processing apparatus includes: an obtaining unit which obtains a stereo signal including an R signal and an L signal; a control unit which generates a processed R signal and a processed L signal by performing (i) a first process of convolving pairs of right- and left-ear head related transfer functions into the R signal so that a sound image of the R signal is localized at each of two or more different positions at a right side of a listener; and (ii) a second process of convolving pairs of right- and left-ear head related transfer functions into the L signal so that a sound image of the L signal is localized at each of two or more different positions at a left side of the listener; and an output unit which outputs the processed R signal and the processed L signal.

A sound field coding system and method that provides flexible capture, distribution, and reproduction of immersive audio recordings encoded in a generic digital audio format compatible with standard two-channel or multi-channel reproduction systems. This end-to-end system and method mitigates any impractical need for standard multi-channel microphone array configurations in consumer mobile devices such as smart phones or cameras. The system and method capture and spatially encode two-channel or multi-channel immersive audio signals that are compatible with legacy playback systems from flexible multi-channel microphone array configurations.

Systems and methods selectively mix a first and second song together during a live performance. The first song has a plurality of first stems, each having stereo audio that combine to form the audio of the first song. The second song has a plurality of second stems, each having stereo audio that combine to form the audio of the second song. A computer, with memory and a processor, executes machine readable instructions of a multiple channel audio mixing application with stored within the memory. The multiple channel audio mixing application plays and mixes audio of at least one of the first stems with audio of at least one of the second stems. The multiple channel audio mixing application is controlled in real-time during the performance to select the at least one first stem and the at least one second stem for the mixing.

A stereo signal processing method includes performing delay estimation on a stereo signal of a current frame to determine an inter-channel time difference of the current frame, identifying a sign of the inter-channel time difference of the current frame is different from a sign of an inter-channel time difference of a previous frame of the current frame, performing delay alignment processing on the first-channel signal of the current frame based on the inter-channel time difference of the current frame, and performing delay alignment processing on the second-channel signal of the current frame based on the inter-channel time difference of the previous frame.

A content reproduction apparatus includes: an information receiving unit that receives first information from a first user terminal capable of providing a first content, the first information including the first content, the information receiving unit receiving second information from a second user terminal capable of providing a second content, the second information including the second content; a list transmission unit that transmits a shared list to the first user terminal, the shared list being created based on the first and second information and including information indicating the first and second contents; a reproduction request receiving unit that receives, from the first user terminal, a request of one of the first and second contents; and a reproduction unit that acquires the requested content from a user terminal that is capable of providing the requested content that is one of the first and second user terminals, and reproduces the acquired content.

A sound signal processing device includes: a vocal remover which generates a first output signal based on first-channel and second-channel sound signals and a first coefficient indicating a vocal bandwidth to be removed; a surround sound processor which generates a second output signal by adding a surround sound effect to the first output signal; an amplifier which amplifies a signal at an amplification factor that is based on a second coefficient; a synthesizer which synthesizes the second output signal with one of the first-channel and second-channel sound signals, and synthesizes a signal that is the second output signal inverted with another one of the first-channel and second-channel sound signals; and a coefficient determination unit which sets the second coefficient such that the amplification factor, used when the vocal bandwidth to be removed is greater than a first bandwidth, is greater than the amplification factor for the first bandwidth.

Systems are disclosed including a television (TV) set having included audio system. The TV set permits control over various functions, at least including audio volume, via a remote control. When the viewer activates the remote volume control, a graphic appears indicating the state of the volume control and, optionally the mute status. The graphic can be presented on the TV screen. In alternate embodiments, the graphic may be presented on a display of the remote, or even some other location, e.g., a different remote control. If a mute button is provided on the remote control, when the viewer activates the mute button, a graphic appears indicating the state of muting and, optionally, the volume control status. The TV set also offers control over various aspects of the audio system, including settings which go beyond volume up/down, generally through some sort of menu system.

An image capture device includes a housing having a lens snout protruding from a front housing surface. A front microphone is mounted below the lens snout. A top microphone is mounted under a top housing surface. The top microphone is positioned to receive direct freestream air flow at a first pitched forward angle. The front microphone is positioned to receive turbulent air flow at a second pitched forward angle. The second pitched forward angle is greater than or equal to the first pitched forward angle. An audio processor receives a first audio signal and a second audio signal from the top microphone and front microphone, respectively. The audio processor generates frequency sub-bands from the first and second audio signals. The audio processor selects the frequency sub-bands with the lowest noise metric and combines them to generate an output audio signal.

A system for processing audio data of the present disclosure has an audio processing device for receiving audio data from an audio source. Additionally, the system has logic that separates the audio data received into left channel audio data indicative of sound from a left audio source and right channel audio data indicative of sound from a right audio source. The logic further separates the left channel audio data into primary left ear audio data and opposing right ear audio data and for separating the right channel audio data into primary right ear audio data and opposing left ear audio data applies a first filter to the primary left ear audio data, a second filer to the opposing right ear audio data, a third filter to the opposing left ear audio data, and a fourth filter to the primary right ear audio data, wherein the second and third filters introduce a delay into the opposing right ear audio data and the opposing left ear audio data, respectively. Also, the logic sums the filtered primary left ear audio data with the filtered opposing left ear audio data to obtain processed left channel audio data and sums the filtered primary right ear audio data with the filtered opposing right ear audio data to obtain processed right channel audio data. The logic further combines the processed left channel audio data and the processed right channel audio data into processed audio data and outputting the processed audio data to a listening device for playback by a listener.

An apparatus for generating an output downmix representation from an input downmix representation, wherein at least a portion of the input downmix representation is in accordance with a first downmixing scheme, includes: an upmixer for upmixing at least the portion of the input downmix representation using an upmixing scheme corresponding to the first downmixing scheme to obtain at least one upmixed portion; and a downmixer for downmixing the at least one upmixed portion in accordance with a second downmixing scheme different from the first downmixing scheme.
