发明名称 Systems and methods facilitating selective removal of content from a mixed audio recording
摘要 Systems and methods facilitating removal of content from audio files are described. A method includes identifying a sound recording in a first audio file, identifying a reference file having at least a defined level of similarity to the sound recording, and processing the first audio file to remove the sound recording and generate a second audio file. In some embodiments, winner-take-all coding and Hough transforms are employed for determining alignment and rate adjustment of the reference file in the first audio file. After alignment, the reference file is filtered in the frequency domain to increase similarity between the reference file and the sound recording. The frequency domain representation (FR) of the filtered version is subtracted from the FR first audio and the result converted to a time representation of the second audio file. In some embodiments, spectral subtraction is also performed to generate a further improved second audio file.

主权项 1. A system, comprising: a memory storing computer-executable components; and a processor configured to execute the following computer-executable components stored in the memory: a communication component that: facilitates a display of information indicative of an option to select one or more sound recordings for removal from a first audio file to generate a second audio file; andfacilitates a display of indicia of the second audio file; anda processing component that generates the second audio file by removing the selected one or more sound recordings from the first audio file based on winner-take-all coding.
