Abstract:
1. A computer-implemented method to reduce noise in audio, wherein the method is implemented in a computer system that includes one or more physical processors and physical electronic storage, the method comprising: obtaining an audio segment that represents voiced audio, wherein the audio segment includes multiple samples having a sample duration; determining, by the one or more processors, for individual ones of a set of offsets that delay the audio segment, a correlation between the audio segment and an individual one of a set of delayed audio segments; selecting a particular offset from the set of offsets, wherein the particular offset corresponds to a greater correlation than other offsets from the set of offsets; determining a particular delayed audio segment based on delaying the audio segment by the particular offset; averaging the audio segment and the particular delayed audio segment to obtain a cleaned audio segment; and outputting the cleaned audio segment.
