This paper describes a method for estimating the amplitude characteristics of room resonance modes from musical audio signals received by two microphones. Room resonance mode information is useful for many audio applications including soundfield equalization and control of the spatial aspects of timbre. Since the proposed method is characterized by blind processing, it does not need signals radiated from a source position. Simulation results obtained by using popular, classical, and jazz musical pieces showed that the proposed method could provide resonance frequencies and Qs, vital information for controlling the effects of resonances.
