We used spectrogram cross‐correlation to compare notes within a song and used the output values to quantify song complexity. To evaluate the efficacy of the new method, we generated synthetic songs to caricature extremes in song complexity and compared selected conventional complexity methods along ...
The recently developed frequency-Bessel transformation (F-J) method is effective to extract multimode surface wave dispersion curves from ambient noise cross-correlation functions (CCFs). However, this method is currently limited to the vertical-vertical component CCFs, and only Rayleigh wave dispersion...
The method can search the cross correlation coefficient of two neighboring high-resolution range profiles with advance-retreat method in spectrogram,based on the principal of generating micro-Doppler effects with the frequency-stepped chirp radar and characteristics of birds. 基于线性调频步进体制雷达微多...
recall by 6% each, compared to the multichannel log-mel spectrograms with intensity vectors. For the MIC format, using SALSA features increased F1 score and localization recall by 16% and 7%, respectively, compared to using multichannel log-mel spectrograms with generalized cross-correlation spectra...

The utility model discloses a Chinese voice control system with a sonogram and a spectrogram in cross-correlation for a driver. The system includes a voice identification control device (1) special for Chinese, a silicon microphone (2), an infrared CCD camera (3) and an automobile vehicle ...
Vocal consistency is measured using spectrogram cross correlation (SPCC) to assess the acoustic similarity between subsequent renditions of the same note. To quantify how SPCC is sensitive to the acoustic discrepancies found in birdsong, we created a set of 40000 synthetic sounds that were designed ...

Cross-correlation provides a fast method to calculate similarities but it is sensitive to durational and spectral fluctuations. Dynamic time warping tolerates durational differences but requires that frequency components match. An extension to dynamic time warping is introduced where frequency is warped in...
