Real trumpet. Waveform shape in Wavelab.



Samplemodeling Trumpet. Very similar waveform shape.



Real trumpet. Plotted are: Amplitude (linear) (blue), Pitch (red) and Centroid (green).
The latter parameter represents the spectral tilt.



Samplemodeling Trumpet. Very similar time course of the three parameters.



Real trumpet. Harmonic amplitudes (Y) vs. time (X axis). Very sharp recruitment/derecruitment (progressive appearance/disappearance of the upper overtones) on most fast staccato notes.



Samplemodeling Trumpet. Very similar shape for the whole phrase.

Please note that all analyses are represented in a linear, rather than decibel scale. This approach actually emphasizes the differences with respect to the acoustic perception.

Analysis of the first two notes.



Real trumpet. Plotted are: Amplitude (linear) (blue), Pitch (red), Centroid (green).
Release completes in 10-20 msec. Fine fluttering of amplitude and centroid.



Samplemodeling Trumpet. Release completes in 10-20 msec. Less marked fluttering on the second note.
