Abstract

One embodiment of the invention provides a recording audio device source determination method and device, wherein the method comprises the steps of: obtaining an device noise signal of a recording to be determined; comparing the obtained device noise signal with device noise signals of a plurality of known recording devices; and using the known recording device, whose comparison result is matching, as a device source of the recording to be determined. The recording audio device source determination method and device solve the problem in the prior art that the device source of a segment of audio recording cannot be accurately determined.

Description

technical field [0001] The invention relates to the technical field of audio analysis, in particular to a method and device for identifying the source of recording audio equipment. Background technique [0002] Recording device detection plays an important role in today's society. In the judicial industry, determining whether a specific piece of audio was recorded by the claimed device can be used to judge the validity and legality of the recording; in copyright disputes, determining the original recording device of a recording can assist in dispute resolution; and so on. At the same time, in the field of audio processing, the detection of audio recording equipment can also provide assistance in important areas such as recording originality and recording tampering detection, because forged recordings are often combined from recordings from different sources. Therefore, there is an urgent need for a method and device for identifying the source of recording audio equipment. ...
