SYSTEMS AND METHODS FOR PRE-FILTERING AUDIO CONTENT BASED ON PROMINENCE OF FREQUENCY CONTENT

摘要

A system is disclosed for processing electronic audio signals. The system includes an input process for receiving digital samples of an electronic audio signal; a frame division process for allocating sequences of the digital samples of the electronic audio signal to respective frames; a frequency transform process for processing the digital samples by frame thereby to register, for each of the frames, a respective frequency set; a filtering process for filtering frequencies of each frequency set into a respective one of a plurality of orders based on relative prominence; an amplitude sequence process for generating multiple amplitude sequences based on the orders, each amplitude sequence n respectively comprising a sequence of amplitudes of the nth-order frequency content in the frames; and an output process for generating user-apprehendable content for a user interface of the system based on the multiple amplitude sequences. Related systems, methods and computer-readable media are also disclosed.
