Computationally efficient data rate mismatch compensation for telephony clocks

摘要

Differing first and second audio signal sample rates from first and second audio signals are matched to each other. If signal sample rates are different, a frame of samples of the first audio signal is duplicated. The duplicate copies are multiplied by a window function and its inverse to produce “windowed frames” first and last samples of which can be deleted or added to increase or decrease a frame rate.
