Sounds enable us to hear things. But in what way? Source representationalism, as I will call it, is a view about how sounds can make other things audible. It says that sounds can fulfil a representational function in perception. In this paper I defend this position by reflecting on the possibility of sound reproduction. That possibility lies at the heart of all sound recording and playback technology. Because of this possibility, the sounds that reach our ears can act as perceptual representations of the sources that emit them, making those sources audible despite their absence from the perceptual situation.
