Abstract: Systems and methods disclosed create one or more digital media presentations based on impact values. In particular, in one or more embodiments, systems and methods generate impact values based on a change in a measure of energy associated with digital audio content over time. For instance, systems and methods generate impact values by calculating a difference in a measure of energy over time in relation to the amount of energy at a particular time period. Based on the generated impact values, systems and methods identify transition points in the digital audio content. Specifically, systems and methods utilize a decaying masking threshold to identify transition points from generated impact values. Moreover, systems and method utilize identified transition points to modify digital visual content displayed in conjunction with the digital audio content.

Abstract: In one embodiment, a device-side audio handling input/output unit (DIO) of a microphone writes audio data generated by the microphone into a ring buffer.

The SIO provides the past audio data from the ring buffer to the software program. Other embodiments are also described and claimed.

Abstract: Examples described herein may include a computing device receiving, from a first playback device, a request for first media content associated with a first playback operation. The computing device sends, to the first playback device, the first media content, and while sending that content, receives, from a second playback device, a request for second media content associated with a second playback operation, this request including information characterizing the second playback operation. Based on that information, the computing device determines whether the second playback operation is higher priority or lower priority than the first playback operation. If the second playback operation is higher priority, then the computing device stops sending the first media content and sends, to the second playback device, the second media content. If the second playback operation is lower priority, then the computing device foregoes sending the second media content and continues sending the first media content.

Abstract: Audio signals are processed by a real-time digital-signal-processing system. A digital-audio-interface is arranged to be connected to a packet-based-network. A control-processor arranged presents a graphical-interface to a user and an audio-source is connected to the packet-based-network. The control-processor receives an instruction to connect the external-audio-source to the digital-signal-processing system via the packet-based-network. In response to receiving the instruction, the control-processor establishes a first-connection-node between the audio-source and the packet-based-network; creates a second-connection-node between the packet-based-network and the digital-audio-interface; and configures a third-connection-node between the digital-audio-interface and the digital-signal-processing system.
