Remediating Soundstudies the phenomena of remixing, mashup and recomposition: forms of reuse and sampling that have come to characterise much of YouTube's audiovisual content. Through collaborative composition, collage and cover songs to reaction videos and political activism , users from diverse backgrounds have embraced the democratised space of YouTube to open up new and innovative forms of sonic creativity and push the boundaries of audiovisual possibilities. Observing the reciprocal flow of influence that runs between various online platforms, 12 chapters position YouTube as a central hub for the exploration of digital sound, music and the moving image. With special focus on aspects of networked creativity that remain overlooked in contemporary scholarship, including library music, memetic media, artificial intelligence, the sonic arts and music fandom, this volume offers interdisciplinary insight into contemporary audiovisual culture.
