title: Detection of early reflections using multifractals.
abstract: Early reflections are not always strong and sparse enough on the timeline to be easily identified when reviewing the impulse response diagram. This paper presents a method for the detection of early reflection in the room impulse response using multifractals. The proposed method uses the distribution of Hölder's exponent calculated for the acoustic impulse response for early reflection detection. The obtained results confirm the assumption that impulse response signals exhibit self-similarity, and that fractal theory can be used for the detection of early reflections.
