Reparation of corrupted audio signals

摘要

Corrupted portions of an audio signal are detected and repaired. An audio signal, including numerous sequential frames, may be received from an audio input device. One or more corrupted frames included in the audio signal may be identified. A frame approximating an uncorrupted frame and corresponding to each corrupted frame may be constructed. Each corrupted frame may be replaced with a corresponding constructed frame to generate a repaired audio signal. The repaired audio signal may be outputted via an audio output device.

主权项

1. A method for repairing corrupted audio signals, the method comprising:
receiving an audio signal, the audio signal comprising a plurality of sequential frames; detecting corruption in a frame in the plurality of sequential frames, the detecting including forming a comparison between a subject frame and one or more frames proximal to the subject frame, the comparison based at least in part on a correlation between the subject frame and the one or more proximal frames; identifying, using at least one processor, a corrupted frame in response to detecting corruption in the frame; constructing a frame corresponding to the corrupted frame, the constructed frame approximating an uncorrupted frame; and replacing the corrupted frame with the corresponding constructed frame to generate a repaired audio signal.
