21. Uses acoustic analysis, including spectrograms and formant measuring and plotting, to describe the vowels. 22. Now we specialize to the case where one transform from an arbitrary representation to the spectrogram . 23. The graphic image of an audio recording in the frequency domain is called a spectrogram or sonogram. 24. Even relatively distant earthquakes are visible in the recorded spectrograms and must also be excluded from analysis. 25. The Wigner distribution gives better auto term localisation compared to the smeared out spectrogram ( SP ). 26. The spectrograms were created from carefully edited recordings of each instrument playing each note of their range. 27. Good strings nearly sound like steel strings, and in spectrograms they show about 7-8 harmonics. 28. A plot of the interaction is referred to as a spectrogram , or, informally, a spectrum. 29. Shazam identifies songs based on an audio fingerprint based on a time-frequency graph called a spectrogram . 30. The machine converts pictures of the acoustic patterns of speech in the form of a spectrogram back into sound.
