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: 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.
