SYSTEM AND METHOD FOR SELECTIVE REMOVAL OF AUDIO CONTENT FROM A MIXED AUDIO RECORDING

摘要

Systems and techniques for removing a sound recording from an audio recording (e.g., an audio recording embedded in a media file) are presented. The system can include an identification component, a first subtraction component and a second subtraction component. The identification component identifies a sound recording in a mixed audio recording. The first subtraction component determines a local linear transformation of the sound recording and subtracts the local linear transformation of the sound recording from the mixed audio recording to generate a new mixed audio recording. The second subtraction component compares one or more segments of the sound recording with one or more corresponding segments of the new mixed audio recording and reduces a power level of the new mixed audio recording based at least in part on correlation of the one or more corresponding segments with the one or more segments.

1. A system, comprising:
a processor; and a memory communicatively coupled to the processor, the memory having stored therein computer-executable instructions, the computer-executable instructions when executed by the processor cause the processor to perform steps comprising:
identify one or more copyrighted sound recordings in a first audio file embedded in a media file;apply one or more signal processing algorithms to the media file to remove at least one of the one or more copyrighted sound recordings from the first audio file to generate a second audio file; andreplace the first audio file embedded in the media file with the second audio file.
