Using single-channel/multi-channel transitions to output an alert indicating a functional state of a back-up audio-broadcast system

摘要

In one aspect, an example method for outputting an alert indicating a functional state of a back-up audio-broadcast system involves: a computing device receiving a first audio-stream that represents first audio-content; the computing device generating a first signature based, at least in part, upon an extent of single-channel/multi-channel transitions included within the first audio-content; the computing device receiving a second audio-stream that represents second audio-content; the computing device generating a second signature based, at least in part, upon an extent of single-channel/multi-channel transitions included within the second audio-content; the computing device making a determination that the generated first-signature and the generated second-signature lack a threshold extent of similarity; and responsive to the determination that the generated first-signature and the generated second-signature lack the threshold extent of similarity, the computing device outputting an alert.

1. A method for outputting an alert indicating a functional state of a back-up audio-broadcast system, the method comprising:
receiving, by a computing device, a first audio-stream that represents first audio-content; generating, by the computing device, a first signature based, at least in part, upon an extent of single-channel/multi-channel transitions included within the first audio-content; receiving, by the computing device, a second audio-stream that represents second audio-content; generating, by the computing device, a second signature based, at least in part, upon an extent of single-channel/multi-channel transitions included within the second audio-content; making a determination, by the computing device, that the generated first-signature and the generated second-signature lack a threshold extent of similarity; and responsive to the determination that the generated first-signature and the generated second-signature lack the threshold extent of similarity, outputting, by the computing device, an alert.
