| For the study of vowels and consonants, the waveform is presented as a spectrogram, on which sounds appear as recognizable visual patterns. |
| Next, we build a KD-TREE to boost up the KNN search in all SIFT features of training spectrogram images. |
| Visualisation can vary according to the choice in the menu 'Voir ': display of the form of wave, of the spectrogram or of ondelettes. |
| Based on the disturbing images contained in the spectrogram, it is easy to see why some might come to this conclusion. |
| Someone immediately created a spectrogram of the audio, which helped to deepen the mystery even more. |
| The waterfall is a time vs. frequency spectrogram in which frequency increases upward, time to the right. |
