Time Frequency Analysis, Modeling and Equalization of Room Impulse Response Functions

Document Thumbnail

Rooms are modeled as linear time invariant systems, where the room impulse response (RIR) describes the transmission characteristics for a specific source receiver pair. Concepts of time frequency analysis are used to decompose the RIR in the time frequency domain, where parametric models are employed to model the different subband signals. The evaluated models perform exact modeling of the early reflections, whereas the decay rate of the reverberant part is sufficiently approximated. Equalization is performed in the time frequency domain, where someone can selectively equalize frequency subbands. Two different rooms are studied as example cases.
