Detection of Room Reflections from a Binaural Room Impulse Response
A novel analysis method for binaural room impulse responses (BRIRs) is presented. It is based on the analysis of ear canal signals with continuous wavelet transform (CWT). Then, the crosswavelet transform (XWT) is used for detection of the direct sound and individual reflections from a BRIR. The new method seems to time-localize the reflections quite accurately. In addition, the proposed analys...

متن کاملSpatial Impulse Response Assessment in Room Acoustics Auralization
Ambisonic impulse responses (also known as the Spatial Impulse Responses) are getting more and more popular in many applications of room acoustics. Measuring, modeling, synthesizing, or simulating acoustics of interiors with emphasize on their spatial features are the examples. The present article shows a methodology of room acoustics auralization assessment using the ambisonics technology. A c...
متن کاملA Non-linear Technique for Room Impulse Response Estimation
Most techniques used to estimate the transfer function (or impulse response) of an acoustical space operate along similar principles. A known, broadband signal is transmitted at one point in the room whilst being simultaneously recorded at another. A matched-filter is then used to compress the energy in the transmission waveform in time, forming an approximate impulse response. Finally, equalis...
متن کاملOn the Robustness of Room Impulse Response Reshaping
In room impulse response (RIR) equalization and reshaping, one of the difficulties is the spatial robustness, because RIRs are very sensitive to the movements of both the signal source and the receiver. For example, the reshaping filter designed for one pair of loudspeaker/receiver or source/microphone positions will be ineffective for another pair. In this paper, we concentrate on loudspreaker...
