Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a sound source with an array of slit shaped waveguide exits. An example embodiment of the sound source includes one or more drivers configured to receive an audio signal current and to generate pressurized air. The sound source further includes one or more chambers coupled to the one or more drivers and configured to direct the pressurized air from the one or more drivers. The sound source further includes an array of two or more slit shaped exits coupled to the one or more chambers and configured to receive the pressurized air from the one or more chambers and to emit sound waves. The directivity of the sound waves is controlled.

Abstract: Disclosed herein are various embodiments for implementing audio enhancements based on video detection. An embodiment operates by receiving an audio clip corresponding to a video clip to be output simultaneously. A background of the video clip is detected. It is determined that the audio clip is to be output with one of wet sounds or dry sounds based on the detected background of the video clip. The audio clip is configured to enhance the determined one of wet sounds or dry sounds when the audio clip is output. The configured audio clip is provided to the audio output device to audibly output the configured audio clip with the enhanced wet sounds or dry sounds when the video clip is output.

Abstract: Embodiments included herein generally relate to managing low frequencies of an output signal. For example, a method may include: measuring a sound pressure level (SPL) of a speaker; dynamically selecting a cutoff frequency for operating a first filter configured to provide a first bass component of a bass element of an output signal and a second filter configured to provide a second bass component of the bass element; providing the cutoff frequency to the first filter to configure the first filter to generate the first bass component based on the cutoff frequency; providing the cutoff frequency to the second filter to configure the second filter to generate the second bass component based on the cutoff frequency; and generating an output signal based on at least one of the first and second bass components.
