摘要： Methods, apparatus and articles of manufacture to identify sources of network streaming services are disclosed. An example apparatus includes a coding format identifier to identify, from a received first audio signal representing a decompressed second audio signal, an audio compression configuration used to compress a third audio signal to form the second audio signal, and a source identifier to identify a source of the second audio signal based on the identified audio compression configuration.

摘要： Methods and apparatus to identify sources of network streaming services using windowed sliding transforms are disclosed. An example apparatus includes a windowed sliding transformer to perform a first time-frequency analysis of a first block of a first received audio signal according to a first trial compression configuration, and perform a second time-frequency analysis of the first block of the first audio signal according to a second trial compression configuration, wherein the windowed sliding transformer includes a multiplier to multiply a vector including a first frequency-domain representation and a matrix including a third frequency-domain representation, a coding format identifier to identify, from the received first audio signal representing a decompressed second audio signal, an audio compression configuration used to compress a third audio signal to form the second audio signal, wherein the audio compression configuration is the first trial compression configuration or the second trial compression configuration, and a source identifier to identify a source of the second audio signal based on the identified audio compression configuration.
