Crepuscule is an ecological sound art installation, bringing together livestreams of dusk soundscapes from around the globe into a centralised space. 

Drawing the model of Reveil (an annual 24-hour broadcast of dawn choruses on  International Dawn Chorus Day), Crepuscule opts for opposing dusk choruses,  tuning into publicly accessible livestreams on Locus Sonus (http://locusonus.org,  a global open microphone network) as the earth rotates toward night. 

The sonification of weather data from each soundscape location provides additional creative overlay, achieved through manipulating attributes of audio processing (such as filtering, reverberation, panning, granular synthesis) to result in altered acoustic environments parsed through the lenses of local circumstances. 

Through drawing together the sounds of dusk, Crepuscule offers a contemplative space to listen to commonalities and contrasts of twilight soundscapes the world over.
