发明名称 Aligning data streams
摘要 The invention aligns two wide-bandwidth, high resolution data streams, in a manner that retains the full bandwidth of the data streams, by using magnitude-only spectrograms as inputs into the cross-correlation and sampling the cross-correlation at a coarse sampling rate that is the final alignment quantization period. The invention also enables selection of stable and distinctive audio segments for cross-correlation by evaluating the energy in local audio segments and the variance in energy among nearby audio segments.
