AB  - Reverberation time is the most important acoustic parameter that describes the acoustic behavior of a room. To measure this parameter, test signals such as pink or impulse noises are usually employed. However, despite its importance, there are few methods aimed at estimating reverberation time from natural signals such as music and speech. In this paper, we propose a method for estimating reverberation time from monophonic instrument recordings by detecting decay parts in the performance using a Non-Negative Matrix Factorization (NMF) algorithm with a Basic Harmonic Constrained (BHC) model. Preliminary results using different databases and instrument models are given for mid-long reverberation times.
