The one or more computer processors generate a cognitive sound mask base on the first information. The one or more computer processors produce a sound cone based on the cognitive sound mask and directing the sound cone at a distracting sound. The one or more computer processors adapt the sound cone based on changes to the surrounding environment.
Dynamic player selection for audio signal processing
A set of signal measures is sent, wherein each signal measure in the set of signal measures corresponds to a respective audio signal received by a playback device in a media playback system and is processed based on a first set of audio processing algorithms. A plurality of signal measures is identified in the set of signal measures. Audio signals corresponding to the identified plurality of signal measures are processed by one or more devices in the media playback system to improve a signal measure of each of the audio signals. The audio signals are processed based on a second set of audio processing algorithms. The processed audio signals are combined into a combined audio signal.
