How to get rid of that bathroom sound

Where does that ugly metallic sound originate from?

As is well known, a room can only develop reverberation on frequencies where room resonances (»modes«) are available. The less of the useful signal “slips through the cracks”, the lower the coloration of the reverb sound. A feedback delay line of 1 sec has a natural frequency density of 1 Hz, so it can form reverberation at e.g. 98, 99, 100, 101, 102 Hz. For a delay loop with just 0.1 sec, i.e. one tenth of the delay,, the natural frequency density would be 10 times more patchy,  e.g. 80, 90, 100, 110, 120 Hz. Continue reading
