Abstract: A communication system establishes a communication session with a communication device via a network and captures, via one or more cameras, a local area within a field of view of the one or more cameras. The local area includes one or more audio sources. The communication system receives, from the communication device, a selection of a respective audio source from the one or more audio source in the local area. The selection indicates that audio originating from the respective audio source is to be prioritized over other audio sources in the local area. The communication system tunes one or more microphones based on a depth of the respective audio source relative to the communication system to optimize reception of audio originating at the respective audio source by the one or more microphones.

Abstract: A system and process for producing a more harmonious musical accompaniment for a musical compilation, the process comprising determining a plurality of probable key signatures for the musical compilation, creating an interval profiling matrix for each of the probable key signatures, finding products of a major key interval profile matrix with each of the interval profiling matrices, summing each of the major key interval products into a running major key sum, finding a product of a minor key interval profile with each of the interval profiling matrices, summing each of the minor key interval products into a running minor key sum, and selecting the most probable key signature from the plurality of probable key signatures by comparing the minor key sum and the major key sum.
