The concatenative real-time sound synthesis system
    CataRT plays grains from a large corpus of segmented and descriptor-analysed
    sounds according to proximity to a target position in the descriptor
    space. This can be seen as a content-based extension to granular
    synthesis providing direct access to specific sound characteristics .Explorative real-time synthesis from heterogeneous sound da-
    tabases allows to exploit the richness of detail of recorded sound
    while retaining efficient control of the acoustic result by using per-
    ceptually meaningful descriptors to specify a target in the multi-
    dimensional descriptor space. If the selection happens in real-time,
    this allows to browse and explore a corpus of sounds interactively
