This paper investigates the application of the technique of Nonnegative Matrix Factorisation (NMF) to the analysis of partial envelopes extracted from a variety of instrumental sounds. Firstly, the initialisation of the NMF method is shown to be important for obtaining useful results. This is followed by an experimental analysis of the bases produced by NMF that demonstrates how they represent prototypical signal features.
