Time alignment of recorded audio signals |
摘要 |
<p>Systems and methods for time-aligning a first and second media signals. The first and second media signals may be audio signals recorded for combining as one audio performance or as an audio portion of an audio-video recording. The system retrieves the audio signals as digital samples generated using a common sampling rate. The system includes at least one coarse alignment function for reducing an initial misalignment between the first and second signal. The coarse alignment function may be configured to generate a coarse-shifted second signal. A fine alignment function determines an aligning time shift between the coarse-shifted second signal and the first signal by performing a cross-correlation between the first signal and the coarse-shifted second signal.
