This is wrong. There are many uses of 6dB/octave or lower
response slopes, such as in areas of feedback stabilization,
line equalization, signal processing, etc. And a -3dB/octave
filter is the easiest way to make pink noise from white noise.
Although it may not seem so to some, pink noise generation is
an important capability to many audio experts. Plus it makes
a great background-masking sound for sleeping.
You still missed the point, in audio, you don't use filter slopes less than 6db/octave,
read up on professional audio, in fact, speakers themselves naturally taper off
(attenuate), when they reach the limit of their frequency response.
Typically, a 24db/octave Linkwitz or Butterworth passive networks are used when you are
crosing over speaker components in professional loudspeakers, and most good home audio
uses at least 12db/octave.
So what was your point? read the threads, it is relating to passive crossover networks.
