Fig. 7From: Detecting fingering of overblown flute sound using sparse feature learningMel spectrogram, feature activations, mean mel spectrum, and selected basis of all possible C#6 fingerings. Mel-spectrogram and feature activations of C#4, C#6, and F#4 fingerings are separated by red vertical lines. Unique feature activations for each fingering and important spectral peaks of basis are annotated with circlesBack to article page
