Abstract: In the more recent past, the area of semantic audio has become an object of special attention due to the increase in attractiveness of signal representations that allow manipulations of audio on a symbolic level. The semantics usually refer to audio objects, such as instruments, or musical entities, such as chords or notes. In this paper we present a system for making minor corrections to amateur piano recordings based on a nonnegative matrix factorization. Acting as middleman between the signal and the user, the system enables a simple form of musical recomposition by altering pitch, timbre, onset, and offset of distinct notes. The workflow is iterative, that is the result improves stepwise through user intervention.
