The acoustics research institute will help verifying the proposed mathematical concepts’ usefulness for applications in acoustics and will cooperate on frame theory research. We aim in solving special phase retrieval problems using low-dimensional projectors and semidefinite programming. We aim at reducing the measurement time of the head-related transfer functions of human listeners, a filter function that is used for human 3D sound perception. Furthermore we will investigate how accurate the statement is, often used in speech recognition, that reconstruction from Mel-Frequency Cepstral Coefficients (MFCCs) is impossible.
