Tracking reflections on Room Impulse Responses

Here there are some functions related to the reflections on room responses.

Here you can download a function that calculates the reflection density, based on the formula proposed in [H. Kuttruff, Room Acoustics, Spon Press, London, 4th edition, 2000]
 
Here you can download a function that determines the onset time (in samples) of reflections in an acoustic impulse response. The method is based on the modified kurtosis approach proposed in [John Usher, "An improved method to determine the onset timings of reflections in an acoustic impulse response" JASA Express Letter, 3/2010]
