VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. For more features including presets and unlimited recording see VOSIS Pro. Visit vosis.app for sound example, demo videos, and user guide!

Features
Read full description

Mobile Sonic Walks proposes a deambulatory listening experience of musical compositions created for and diffused in a chosen site through geolocalisation by the students of the Centre for Music and Technology of the Sibelius Academy at the Uniarts Helsinki. Wandering around in the area you explore the sonic walks with your headphones and mobile phone. You might very well discover hidden aspects of the environment revealed by the compositions and be surprised, although you have been walking there many times. Each sonic walk is different, and their number keeps growing. So, come back and enjoy the variety of styles, composition ideas and sonic worlds in relation to the site. Mobile Sonic Walks are produced with the SoundWays platform developed by the Collective MU.
