Modulations of Amplitude in Mobile Acoustical Heritage

Nowadays, cultural heritage has been preserved digitally more than physically. However, most of the research works have been focusing more on preservation of video elements even though preservation of audio is equally important. In this paper, the possibilities of generating different sounds in an acoustical heritage through the modulations of sound characteristics are explored on mobile devices. The modulations of the amplitude are based on tiles. In the proposed method, the user uses the one-tap gesture to initiate the start of sound changes on the physical interface of an immersive panoramic view on mobile platform by altering the amplitude of recorded audio piece and consequently producing different audible results. User interactions happen along the x and y-axes following the standard iOS system coordinate. This paper also demonstrates the programming method based on tiles and direct modulations of acoustical heritage in panoramic view with the interaction of the users in order to provide enhanced sensorial audio experience and acoustical engagement in action space on mobile platform. The result of the evaluation has shown that the volume playback has different amplitudes from the different coordinates that the users have tapped on.
