### What’s new?

#### Are Early Reflections desirable for late reverberation?

My interest and research on the perception of acoustic spaces - Early Reflections in particular - is reflected on
a new subpage: psychoacoustic.html.

#### New slope matching algorithm

New slope matching algorithm for zita style fdn’s. I worked extensively on slope matching allpass filters and
ended up using the (expensive) quadratic equation to solve x = −g∕(1 − g^{2}) :

where d is the distance from the sound source; t1 and t2 are reflections.

A possible approximation, which proved to be useful in many contexts would be:
