Paper short abstract:

In a world aiming to reach the holistic understanding of the basic phenomena through multidisciplinary approaches Sound and Music are revealing their hidden emotional weight and shaping memories abilities through experimental lab research techniques of the 21st Century.

Paper long abstract:

The last decades allowed significant progresses on spectral and biometric studies of the Voice, so now it can be shown through analytical means the uniqueness of each individual's "voice signature". Beyond this property the preliminary spectral analysis performed on the registered voices revealed the existence of some certain features. For example, for a notorious singer (the main case study of this presentation -Amália Rodrigues) there are notable differences between the measured values of the characteristic parameters of the same song recorded in the studio or during live performances. The presence of an active audience (having an established dialogue through applauses /sings or shared language) or of a less reactive one leads to significant changes on singer's performing parameters, these changes being quantifiable through the registered lab researches on microstructural patterns.

Some of the available recordings were digitized, analyzed and quantified with dedicated voice analyze and modeling software, the preliminary data showing the evidence of an energy exchange between the artist and the public over the performances otherwise, the evidence of the shared emotion .

The intensity of this exchange can be determined through the rate of the frequency's increase on the audio signal of the same type of songs or more obvious through the increases on the frequency level between the first interpretation of a song in the show and its second performing during encores. The density of energy, as one of the possible metrics of shared emotion, is spectacularly shaping different patterns of the sound microstructural "fingerprints.
